Another opportunity to reflect on the progress made and the challenges that remain in our objective of improving the lives of people with Myalgic Encephalomyelitis (ME, sometimes referred to as ME/CFS). We approach the twentieth anniversary of Invest in ME Research and continue to emphasise the urgent need for real, lasting change for people with ME. Our work has spanned pragmatic advocacy, raising standards in education and clinical care, and facilitating and funding biomedical research. The vision of a Centre of Excellence for ME - an integrated hub for research, clinical trials, and patient care - has been a core element of our strategy. Over the past fifteen years, this vision has taken root at Norwich Research Park, where we have supported pioneering researchers, funded multiple PhD and postdoctoral positions, and enabled the UK’s only clinical trial for ME. This progress has only been possible through the dedication of our supporters and the collaborative spirit of the leading researchers. Norwich Research Park provides a unique environment, combining university, medical school, hospital, clinical trials unit, genomics institute on a single site, with a nearby ME clinic supporting research. This impressive setting has allowed us to lay the groundwork for sustainable progress. Our collaborations with researchers such as Dr Ian Gibson and Professor Simon Carding have resulted in a unique momentum and innovative projects that address the biomedical basis of ME, while support from The Hendrie Foundation, LunaNova and our wider community of supporters. Recognising that meaningful progress depends on collaboration, we established European networks to enhance research capabilities and promote greater cooperation among scientists across Europe, allowing harmonisation of methodologies and facilitating joint projects. This also included initiating a European network to strengthen the link between clinical experience and research priorities, ensuring that patient needs are central to our efforts. With the launch of Young EMERG (YEMERG), we are facilitating development of the next generation of ME researchers, providing mentorship and resources to ensure this momentum continues. Invest in ME Research Page 1 of 43 ׉ 7cassandra://FyywSeX-sdz7FkJVQhliGc39-cIbT8RoyJNF181KNPM$`̵i$BPv׉E Journal of IiMER May 2025 Over nearly two decades, our charity has worked tirelessly to advance ME research and facilitate meaningful collaborations. Whilst being thankful for the foundations our supporters have enabled and established - evident in the growth of research networks at Norwich and across Europe - we must also acknowledge the persistent challenges that have tempered progress. Our recent experience with the DHSC working group, where our proposals to accelerate research and collaboration were regrettably ignored, serves as a reminder of the obstacles that arise when the same incumbent influences consistently dictate the pace of change, steering outcomes towards predetermined conclusions. As highlighted in our article Déjà vu?, published even before we were invited to be involved, such patterns risk perpetuating a status quo in which opportunities for genuine progress are repeatedly missed. Despite these setbacks, our resolve remains undiminished. The robust research infrastructure and partnerships built through the dedication of our supporters and the wider ME community now offer an invaluable platform for meaningful advancement. It is vital that this momentum is not lost - nor that existing efforts are overlooked, unnecessarily duplicated, and especially not reinvented at the expense of real progress. Instead, we should support the foundations already established, ensuring that the groundwork laid by our collective efforts can be fully realised for the benefit of people with ME. To new researchers joining our field: you are entering a community that values innovation, collaboration, and the resolve to challenge inertia. In these challenging times for researchers, your commitment is welcome. We invite you to build on these foundations and work with us to improve this critical situation for people with ME and their families. Our annual international conferences and colloquia have become important platforms for knowledge exchange, setting research priorities, and fostering new collaborations. This year’s BRMEC14 colloquium and IIMEC17 conference, focused on translating research into diagnostics and treatments, demonstrate our intent to bridge the gap between scientific discovery and meaningful patient outcomes. Systems biology, which integrates multiple layers of biological data, remains a key focus for discovery of the complex nature of ME. As we come together for this week of learning, discussion, and collaboration, we invite all delegates to engage fully, share ideas, and forge new partnerships. The collective expertise and dedication within this community are vital to our shared goal: a future where people with ME receive the care, understanding, and hope they deserve, and where a sustained strategy of biomedical research ultimately leads to effective treatments.

This vital contribution continues a longstanding partnership that has significantly advanced biomedical research into Myalgic Encephalomyelitis (ME) since the conference series began in 2006. The charity dedicates substantial resources to organising the conference week, which includes not only arranging the main events but also supporting the European ME Research Group (EMERG), the Young EMERG early-career researcher network, and an increasing number of researchers and clinicians. This support fosters collaboration, brings new expertise into the field, and helps overcome barriers to research progress at a time when funding is increasingly threatened by political and societal challenges. Thanks to supporters like IMET, Invest in ME Research has been able to sustain and augment these efforts each year. IMET’s commitment is especially notable for its longevity and selflessness; for over twenty years, they have supported Invest in ME Research without seeking promotion or special recognition. As a founding member of the European ME Alliance, IMET has played a key role in building a pan-European research community. Their past donations have helped fund important projects such as research at the UK/European Centre of Excellence for ME at Norwich Research Park. This year, IMET’s sponsorship frees Invest in ME Research resources to focus on building research capacity by subsidising attendance for early-career researchers at the IIMEC17 conference, the 14th Biomedical Research into ME Colloquium (BRMEC14), and the Young EMERG Workshop. These events nurture the next generation of ME researchers by reducing financial barriers, encouraging participation, and fostering connections with established experts. Supporting emerging researchers is crucial for sustaining momentum and encouraging innovative, cross-disciplinary approaches. IMET’s support also reflects a broader tradition of generosity from Irish organisations and individuals towards the charity’s efforts in facilitating research into ME, funding fellowships, clinical trials, and international CPD-accredited scientific meetings. These efforts have created opportunities for healthcare professionals, patients, and carers to engage with the latest developments in ME research. The conference week continues to attract and expand a family of international researchers from Europe, North America, and beyond, including representatives from the NIH and CDC, providing a unique platform for advancing biomedical research into ME through open, collaborative dialogue. Invest in ME Research extends its sincere thanks to the Irish ME Trust for their enduring generosity and partnership.

The group is linked to the European ME Research Group (EMERG) The Young EMERG 2025 Symposium for Promoting the Advancement of Research Knowledge in ME (SPARK ME) is another a unique gathering tailored for young and early career researchers, and medical students, passionate about advancing research in ME and post-viral illnesses. Organised by Young EMERG and Invest in ME Research, YE SPARK ME aims to facilitate collaboration, knowledge exchange, and networking among early career researchers in the field of ME. At SPARK ME, early career researchers have the opportunity to showcase their work through oral and poster presentations. The event offers a safe space for early career researchers to discuss challenges and gain valuable insights into pursuing ME research. Through engaging talks, participants will be equipped with knowledge of postdoctoral research funding opportunities, career development and ME/CFS study design and much more! For this year’s event the different nationalities and career stages of those attending the workshop consist of 25% of attendees being UK-based, 45% are based in other European countries, and around 20% are US-based. Then there are a few people from other countries, such as Australia and South Africa. Around half of them are PhD students, the rest are post-docs, other academic researchers, undergraduate students, and some other various job descriptions. The attendees represent a wide range of research fields, primarily within the biological sciences, including electrophysiology, immunology, neuroscience, genetics, metabolomics, and metagenomics. Additionally, participants from the medical sciences, such as medicine, cardiology, and public health, and from computational and data sciences, including biomarker mining, bioinformatics, and statistics, contributed to the vibrant interdisciplinary atmosphere. The event even attracts PIs – although not always with the approval of the younger researchers! “The most helpful aspect of the conference was] … giving perspectives from other fields and learning how they connect to my own” Young EMERG published a well-received paper last year – Advancing Research and Treatment: An Overview of Clinical Trials in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Future Perspectives - https://www.mdpi.com/2077-0383/13/2/325 Invest in ME Research Page 4 of 43 ׉ 7cassandra://lVr06nkKuyFEQMfzgA0OIhzAtAfWJZyxafwdTL0jc5w#`̵i$BPvi$BPv{בCט{u׉׉ 7cassandra://NuGokIBiShM0Ru4zMwv3WjmQBcGKZSnwzW8hTI3VEfw` ׉ 7cassandra://KVbNO4h7K4afa5EJa5NCMGQd954GbZwj6H09tv7OwJMr``S׉ 7cassandra://_ou3y27twEvxLH4Kuy5CyFZsiX5MYBKYHmttXLjk55E`̵i$EPvט{u׉׉ 7cassandra://WLJICIgXX7qMmvHu6W6hk8r4oyQNcny429-W4EtP7r0:` ׉ 7cassandra://tO3lFDzrNIAnlQHG4ZKsxxCxCabzykPKPVwprjO2Kmgv`S׉ 7cassandra://djWZSX75O_E37jsV4sPVcAFTeFisJgs3ESxmhBtA1_M!`̵i$EPvנi$EPvCS?9׉H(https://www.investinme.org/iimec10.shtmlGׁ ׁ r׉E7Journal of IiMER May 2025 Young EMERG Joins WHO Youth 4 Health In 2023, the European ME Alliance (EMEA) achieved Non-State Actor accreditation from WHO’s Regional Office for Europe, enabling active participation in WHO meetings and ensuring ME representation in WHO initiatives. In 2024, as part of the EMERG/EMECC/EMEA/YE strategy, we facilitated the connection of Young EMERG to the WHO Youth4Health network, strengthening ties between ME advocacy and European health initiatives. Johanna Rohrhofer from the Medical University of Vienna has been the representative for YE and passes that role to another in YE this year. At last year’s WHO Regional Committee for Europe, key groups including the European ME Research Group (EMERG), and Young EMERG (supported by WHO’s Youth4Health) convened in Copenhagen to highlight ME as a major health challenge and promote youth engagement in European health policy. Their shared priorities include:  Official recognition of ME/CFS as a somatic illness by WHO  Implementation of WHO ICD codes for ME/CFS in national health systems  Ensuring timely physical, financial, medical, and social support for sufferers  Incorporating the latest scientific evidence into medical curricula  Developing disease registries using current diagnostic criteria  Securing funding for biomedical research  Rapidly advancing Centres of Excellence for MES During the NSA event, Young EMERG represented youth perspectives in a private meeting with Dr Hans Kluge, WHO Regional Director for Europe. As our first Youth4Health focal point, Young EMERG connects early career researchers, fostering long-term commitment to ME research, care, and policy improvements. Through Youth4Health, WHO offers young people a platform to influence health policy, amplifying ME issues within WHO discussions and promoting understanding among youth and healthcare stakeholders. The partnership equips young researchers with resources to build collaborative, interdisciplinary networks and advocate for funding during critical career stages.

These bursaries are designed to support undergraduate students in gaining practical experience in biomedical research, with a focus on Myalgic Encephalomyelitis (ME). This initiative aligns with the charity's objective of raising education and fostering the next generation of doctors and researchers. The discovery of new treatments relies heavily on research into the causes of the disease. The Summer Student Bursaries provide a unique opportunity for students to contribute to this vital research while developing their skills and knowledge in biomedical science. Simultaneously, it raises awareness of ME and influences the next generation of the medical community, which in turn influences peers. This is not the first time Invest in ME Research has funded summer students, having done so in recent years. Three eight-week bursaries are being offered, with involvement in various research projects at the Quadram Institute. These projects include investigating the virome in mucosal cavities, exploring fungal and yeast diversity, identifying microbes driving inflammation, analysing the prevalence of fungal infections, and studying gastrointestinal viruses in ME patients. Each project offers hands-on experience with advanced molecular and microbiological techniques, providing a solid foundation for future careers in biomedical research. There have been over 50 applications for these Invest in ME Research Summer Student bursaries. Quadram Institute had interviewed candidates and offered three applicants these awards, and they have all been accepted. The successful applicants will begin in July.

These fellowships are designed to advance biomedical research into myalgic encephalomyelitis (ME), focusing on understanding disease mechanisms and developing new treatments. Both fellowships address the critical need for dedicated ME research funding and expertise in the UK. They strengthen the research base at the centre, and support ongoing clinical trials and PhD studentships. Ian Gibson Fellowship Launched in 2022 and named in honour of Dr Ian Gibson, this is the first postdoctoral fellowship in the UK dedicated to ME research. The fellowship supports fundamental biomedical studies, particularly in gut health, microbiology, and immunology. It is part of the broader strategy to develop further a UK Centre of Excellence for ME at Norwich Research Park, ensuring continuity and growth of ME research in a collaborative, multidisciplinary environment. LunaNova Fellowship Introduced in 2023 and funded by the technology company LunaNova, this two-year fellowship further expands ME research capacity at the Quadram Institute. The LunaNova Fellowship focuses on the gut-immune-brain axis and the search for biomarkers, with strong links to international partners, including the European ME Research Group. This collaborative approach brings together expertise from across Europe and supports the development of a robust research ecosystem for ME. Our LunaNova fellowship – Krishani Perera Dr Krishani Perera, PhD, was awarded the Invest in ME Research Luna Nova Fellowship and joined Professor Simon Carding’s laboratory at the Quadram Institute of Bioscience (QIB) in Norwich in July 2024. As a recent entrant to the field of ME research, Krishani is highly motivated to contribute to ongoing investigations into the causes and treatment options for ME/CFS at QIB. Her two-year fellowship will focus on understanding the link between the reactivation of human endogenous retroviruses (HERVs)-genes embedded within our genome, usually kept inactive-and the accelerated ageing of immune cells in ME/CFS patients. This work is based on clues from previous studies which have shown either dysfunctional immune cells, signs of premature ageing, or the reactivation of different HERV families in people with ME/CFS. Krishani’s project aims to demonstrate a causal link between these findings, exploring whether the reactivation of HERVs plays a key role in cellular and immunosenescence, which could help explain the origins of Page 7 of 43 Invest in ME Research ׉ 7cassandra://Yh6Bfgfhm1fHoALN-fzK7tQg8zP4mmZkFp5gDKvM5ys&`̵i$BPv׉E Journal of IiMER May 2025 ME/CFS. Her research will also contribute to the RESTORE-ME clinical trial, a phase IIb, placebocontrolled study investigating microbiota replacement therapy in ME/CFS patients at the Quadram Institute. Krishani brings a strong background in virology and molecular biology, having completed her PhD in Pathobiology and MSc in Veterinary Biomedicine at Kansas State University, USA. Her research there focused on discovering and characterising antiviral compounds against animal and human coronaviruses, including SARS-CoV-2, and studying how viruses develop resistance to these treatments. She also worked on animal caliciviruses and explored host susceptibility to SARS-CoV-2 during the COVID-19 pandemic. Following this, Krishani undertook postdoctoral research at Irset in Rennes, France, where she investigated immune responses and the persistence of viruses such as Zika, Chikungunya, and Mumps in immune-privileged sites in the human body. At the Quadram Institute, Krishani is examining ME/CFS through a microbial lens, focusing on the detection of microbes-especially viruses-that may be involved in the condition. She explains, “My research focuses on detecting microbes, particularly viruses, that may be involved in ME/CFS.” ME/CFS is a serious and often disabling condition, affecting an estimated 17 to 24 million people worldwide, including around 250,000 in the UK. Despite its prevalence, ME/CFS remains underrecognised and is frequently misunderstood and misdiagnosed. Those affected experience a wide range of symptoms, including extreme exhaustion following minimal mental or physical activity (postexertional malaise), immune dysfunction, and digestive issues. These symptoms can make daily life overwhelming, and many people with ME rely on carers for basic activities such as eating and personal hygiene. As Krishani notes, “Many individuals with ME/CFS face severe mobility issues. This means we must prioritise patient accessibility and comfort when collecting samples, ensuring our studies are as inclusive and accommodating as possible.” Currently, there is no cure for ME/CFS and the exact cause remains unknown. Krishani explains, “We believe it’s due to a combination of factors, including viral or bacterial infections, immune system dysfunction, and persistent immune activation.” In Professor Carding’s group, Krishani and her colleagues are striving to bring scientific clarity to ME/CFS and to help those affected by this debilitating condition. While no single virus has been definitively linked to ME/CFS, several are suspected to play a role, with many patients reporting viral infections such as SARS-CoV-2 prior to the onset of symptoms. Some viruses can persist in the body long after the initial infection and may contribute to ongoing immune dysfunction, but research to date has not provided a clear picture and conclusions remain elusive. Krishani is investigating the links between microbes present in mucus and blood and the development of ME/CFS. At the Quadram Institute, a study funded by Invest in ME Research-the COMPASS ME Study-will analyse the mucosal microbial communities, including viruses, bacteria, and fungi, in individuals with and without ME/CFS. She is also examining the communities of viruses in the bloodstream of people with ME/CFS to determine whether they play a role in immune dysregulation.

Her path to researching the role of viruses in ME/CFS is grounded in her extensive experience in molecular virology. She says, “My expertise spans from identifying antiviral compounds to understanding how viruses develop resistance.” Her work has deepened her interest in how certain viruses evade immune responses and contribute to long-term health issues. Looking ahead, Krishani hopes to develop future diagnostics for ME/CFS. “Longer term, I want to understand ME/CFS pathology and disease progression. By identifying potential causes and underlying mechanisms, I hope to contribute to the development of better diagnostic tools for early and accurate detection. Ultimately, my goal is to explore effective and targeted treatments to improve patient outcomes and quality of life.” She stresses the complexity of ME/CFS: “Because there is no one known cause for ME/CFS and it’s a complex condition with interconnected biological mechanisms, we need to be cautious when interpreting data on potential links between symptoms, immune dysfunction and microbes. A simplistic approach could overlook crucial factors, so a comprehensive, interdisciplinary perspective is essential when studying ME/CFS.” Krishani concludes, “At the end of the day, it’s not just about scientific rigour but about raising awareness-not only to improve research and treatment options but also to foster empathy and respect for those living with this invisible illness. By understanding ME/CFS, we can help create a more supportive and inclusive world for those affected.” She expresses her gratitude: “I am very grateful to the Invest in ME Research charity and the LunaNova fellowship for their support with funding for the research I am conducting.” Further information: https://tinyurl.com/Quadram-Krishani Light ME Up: Red Light Therapy Study for ME at Quadram Institute The Quadram Institute, in partnership with the University of East Anglia (UEA) and with support from Invest in ME Research, is conducting a feasibility study called Light ME Up to explore the potential of red light therapy for ME. Launched in 2024, this study investigates whether photobiomodulation can help relieve symptoms of ME. By targeting mitochondrial dysfunction, thought to contribute to ME’s debilitating fatigue, the study aims to open new avenues for treatment. Light ME Up was set up initially to involve ten participants with ME, recruited through the charity’s network. This has now been expanded.

The Light ME Up study is a modest yet significant step in ME research, reflecting IiMER and Quadram’s commitment to exploring novel interventions. By testing PBM’s feasibility and refining remote research methods, the study lays groundwork for scalable trials and enhanced patient engagement. From Broken Wings to Clearer Skies: Finding New Paths for Connection Invest in ME Research has been active on Twitter (now X) since the early days of the platform's existence. Twitter has long served as a valuable tool for raising awareness about the charity’s work, including the research being funded and facilitated at the Norwich Research Park centre. Yet it will not have escaped many people's notice that times have changed. The last thing people with ME, or their families and carers, need is added stress or an environment that many now consider toxic and unproductive. Despite this, a platform is still necessary for learning, sharing, and discussing ME-related issues and progress. Invest in ME Research has been active on Bluesky for some time, and we are gradually sharing more of our news on this platform.

ME, classified as a neurological disorder (ICD-11: 8.E49), presents with diverse symptoms affecting immune, neurological, endocrine, and metabolic systems. Despite decades of research, its mechanisms remain unclear, with hypotheses including viral triggers, immune dysregulation, and mitochondrial dysfunction. The disease’s complexity and patient heterogeneity have hindered progress in identifying causal pathways and targeted treatments. Systems biology offers a holistic framework by integrating genomics, proteomics, metabolomics, and environmental data to model complex biological networks. This approach reveals emergent properties and dynamic processes often missed by traditional methods, making it well suited to ME’s multisystem nature. Key features include multi-omics integration, computational modelling, and network analysis, which together help identify crucial biological interactions and therapeutic targets. A core strength of systems biology is its ability to bridge laboratory discoveries with clinical observations. By integrating patient data with experimental findings, researchers can stratify patients into meaningful subgroups, aiding biomarker discovery and personalised medicine, as well as informing clinical trial design.

Computational Modelling: Dezso Modos applies advanced models to decipher complex biological networks and signalling pathways, enhancing understanding of disease dynamics and supporting novel therapeutic target identification. Recent studies show that ME/CFS, Gulf War Syndrome, and Fibromyalgia share metabolic disruptions, especially in lipid metabolism and energy production, alongside increased oxidative stress driving cellular damage and inflammation. Identifying reliable biomarkers is essential for earlier diagnosis and targeted therapies, with comprehensive metabolomic and proteomic analyses playing a vital role. Invest in ME Research’s focus on systems biology at BRMEC14 aims to help solve this continuing and devastating medical puzzle. By integrating computational, experimental, and clinical perspectives, systems biology stands to transform understanding of ME-from pathogenesis to treatment innovation. This holistic approach is crucial for addressing the variability and elusive nature of the disease. Long Covid and ME/CFS: Overlapping symptoms, shared research, and implications for diagnosis and treatment Long Covid and ME/CFS share striking similarities, necessitating research into their overlapping symptoms, shared biological mechanisms, and implications for diagnosis and treatment-hence their inclusion in the BRMEC14 colloquium. Both conditions, often triggered by viral infections, present with post-exertional malaise (PEM), profound fatigue, cognitive dysfunction, and autonomic issues, complicating differential diagnosis. Recent studies suggest common pathophysiological pathways, including immune dysregulation, mitochondrial dysfunction, and neuroinflammation, driving collaborative research. A 2023 study in Nature Reviews Microbiology noted that up to 50% of Long Covid patients meet ME/CFS diagnostic criteria, with PEM as a hallmark. Shared biomarkers-such as elevated cytokines, reduced natural killer cell function, and altered metabolomic profiles-point to common immune and metabolic deficits. For example, a 2024 NIH study identified T-cell exhaustion in both conditions, while metabolomic analyses reveal hypometabolism, suggesting potential diagnostic markers. These findings underscore the need for precise diagnostic tools to distinguish or co-diagnose the conditions, as misdiagnosis risks inappropriate treatment. Research synergies are accelerating progress. Long Covid’s global attention has boosted funding for ME/CFS. Trials targeting mitochondrial function, such as photobiomodulation (Quadram Institute, 2024), and immunomodulators like rapamycin (Mayo Clinic, 2025) show promise for both. BRMEC14 brings together researchers, clinicians, and patient advocates to discuss these advances. The focus on immunology, metabolomics, and patient-involved research provides a platform for sharing data, refining hypotheses, and planning multicentre studies, strengthening the ME/CFS research ecosystem. The implications are significant. Improved diagnostics could emerge from validated biomarkers, while shared treatment strategies may alleviate symptoms like PEM and fatigue. However, challenges remain, including heterogeneous patient cohorts and limited funding. BRMEC14 aims to foster collaboration and support efforts to translate research into better care for those with ME/CFS and Long Covid.

Artyomov and Tomas Paulenda (Washington University in St. Louis, USA) BRMEC14: Itaconate modulates immune responses via inhibition of Peroxiredoxin 5 Professor Maxim N. Artyomov and Dr Tomas Paulenda are leading researchers in immunometabolism and systems immunology. Their recent work demonstrates that itaconate-a metabolite produced during inflammation-inhibits peroxiredoxin 5 (PRDX5), an antioxidant enzyme critical for managing mitochondrial oxidative stress in immune cells. This non-covalent inhibition alters mitochondrial peroxide levels and the redox environment in activated macrophages, significantly affecting immune signalling pathways and fine-tuning inflammatory responses. This discovery builds on Artyomov’s earlier work exploring itaconate’s role in modulating macrophage behaviour and inflammation. In light of their recent important research, the charity is delighted to announce the addition of Maxim N. Artyomov and Tomas Paulenda to the BRMEC14 programme. These findings are highly relevant to ME, a condition marked by immune dysregulation, mitochondrial dysfunction, and persistent oxidative stress. The study links itaconate’s regulation of mitochondrial redox balance to mechanisms often impaired in ME, suggesting that by inhibiting PRDX5, itaconate may influence the handling of reactive oxygen species in immune cells. This could contribute to the mitochondrial dysfunction and abnormal oxidative stress observed in ME patients.

With over 35 years on the Harvard faculty, he is internationally recognised for his research into exercise intolerance in ME/CFS and related conditions. Dr Systrom’s work focuses on invasive cardiopulmonary exercise testing (iCPET), which measures cardiovascular, respiratory, and metabolic responses during maximal exercise. He has shown that many people with ME/CFS experience impaired cardiac preload, reduced peak cardiac output, and poor systemic oxygen extraction during exercise. These abnormalities reflect neurovascular dysregulation and autonomic dysfunction rather than deconditioning, and his studies indicate that small fibre neuropathy may contribute to these circulatory and metabolic problems. His research helps explain the profound fatigue, post-exertional malaise, and orthostatic intolerance in ME/CFS. He is currently leading a major study using muscle biopsies to investigate skeletal muscle mitochondrial dysfunction in ME/CFS and has completed the first randomised controlled trial of pyridostigmine in ME/CFS, which improved exercise capacity by increasing cardiac output and right ventricular filling pressures.

Dr Oltra’s research explores how iPSCs can be used as “sensors” to detect disease-specific metabolic imbalances and responses to environmental cues. By exposing healthy iPSCs to plasma or serum from ME/CFS patients, her team studies changes in cell morphology, differentiation, growth, and metabolic activity. These changes can reveal the presence of disease-related factors in patient body fluids and provide evidence of altered cellular metabolism in ME/CFS. This approach offers several advantages over traditional cell lines or primary cell cultures. iPSC-based assays can be standardised, are highly sensitive to metabolic and environmental changes, and allow for high-throughput screening.

He has published more than 140 scientific papers in peer reviewed journals, mainly on the autonomic nervous system and more recently on complex diseases possibly resulting form HPV-vaccination. For over 35 years, he has worked clinically and in research with dysfunction of the autonomic nervous system. Such dysfunction may lead to symptoms from a number of different organs often dominated by diminished control of blood pressure and heart rate. Over the past 5 years, he has worked clinically and in research with patients who suspect side effects due to HPV vaccination to be the cause of a number of symptoms, common to those seen in chronic ME. Dr Mehlsen is co-chair of the European ME Research Group (EMERG). Dr Mehlsen ran a clinic for ME patients in Copenhagen, Denmark, until recently where he provided clinical care and applies his research insights to patient management. He has been actively involved in developing a European consensus on treatment protocols for ME/CFS, aiming to establish standardised approaches that can be adopted across clinical settings. His research interests include methods for studying autonomic cardiovascular control, mathematical modelling of cardiovascular responses, and the neuroinflammatory reflex. Dr Mehlsen is also involved in discussions on clinical trials and standards within the ME research community, including chairing sessions at the Biomedical Research into ME Colloquium (BRMEC13). His work integrates clinical observation with advanced physiological and mathematical analyses to explore the underlying mechanisms of ME and related disorders.

Professor Ron Davis Professor of Biochemistry and Genetics at the Stanford School of Medicine in Stanford, California, USA IIMEC17 - Diagnostic Breakthroughs and Therapeutic Horizons for ME Ron Davis, PhD, is Professor of Biochemistry and Genetics at Stanford School of Medicine and Director of the Stanford Genome Technology Center. He is internationally recognised for his leadership in developing innovative technologies and for his longstanding commitment to advancing research into ME/CFS. Professor Davis’s recent work has focused on identifying reliable diagnostic biomarkers and exploring new therapeutic avenues for ME/CFS. His team developed the “nanoneedle” diagnostic platform, which distinguishes ME/CFS patients from healthy controls by measuring changes in the electrical properties of blood cells exposed to stress. This technology has shown high accuracy in early studies and is now being tested in larger cohorts to confirm its utility as a clinical diagnostic tool. The platform is also being used to screen potential drug treatments by observing whether candidate compounds can normalise the abnormal cellular responses seen in ME/CFS samples. In addition to the nanoneedle, Professor Davis’s group has pioneered a neutrophil assessment platform, revealing that neutrophils from ME/CFS patients move more slowly than those from healthy individuals. This work is ongoing and may yield further diagnostic markers. His research has also highlighted the role of factors in blood plasma that may drive the illness, with ongoing investigations into possible infectious or metabolic contributors. Professor Davis collaborates widely with international research teams and is involved in developing animal models to study disease mechanisms and test therapeutic candidates. At IIMEC17, he will summarise progress in biomarker discovery, the development of new diagnostic tools, and early results from therapeutic screening. His work is closely aligned with the goals of Invest in ME Research, aiming to accelerate the path toward effective diagnosis and treatment for ME/CFS. He is a world leader in biotechnology, especially in recombinant DNA and genomic methods applied to biological systems. As Director of the Stanford Genome Technology Center, he focuses on integrating nano-fabricated solid-state devices with biology.
