As discussed in the paper, there is more evidence for abnormal immunometabolism in ME/CFS. Maya utilized her expertise in flow cytometry and Seahorse flux analysis to demonstrate this dysfunction. She isolated natural killer (NK), helper T (CD4), and cytotoxic T (CD8) cell populations from both healthy donors and people with ME/CFS. These immune cell populations were studied in their circulating state and after stimulation. The stimulation process aims to mimic an immune response. Maya’s findings showed that all three of the cell types have an increased use of fats to power their activities when compared to healthy donors. Her results show that ME/CFS immune cells have a greater reliance on fats for energy when they are stimulated. Overall, these findings support the presence of an altered metabolic state in certain immune cells in individuals with ME/CFS.
Maya outlines these findings in her graphical and video abstracts inserted below.
On September 23, 2020, a CDC ME/CFS Stakeholder Engagement and Communication (SEC) call took place, featuring a presentation by Dr. Maureen Hanson, ENID Center Director, on “Immune Dysfunction in ME/CFS”. Dr. Elizabeth Unger, Branch Chief of CDC’s Chronic Viral Diseases Branch, provided CDC programmatic updates. The SEC call transcript, audio, and presentation slides are now available on the CDC’s website. Direct links to specific content, including Hanson’s slideshow presentation, are below.
On November 4-5, 2020, Cornell University and Weill Cornell Medicine held a COVID-19 Summit to exchange information about research into the disease ongoing at both institutions. Dr. Maureen Hanson presented a “flash” talk with three slides to introduce Cornell COVID-19 researchers to the similarity between long-haul COVID-19 and ME/CFS. Content from Hanson’s talk is below.
At the Swedish RME annual ME/CFS conference on Oct. 14, 2020, Clinical Core Co-Director, Dr. Betsy Keller, presented virtually on post-exertional malaise (PEM). Keller goes into detail on PEM by covering what it is, ways to assess impairment due to PEM, and strategies to minimize PEM. Her full talk “PEM: Strategies for determining and managing the cardinal symptom of ME/CFS” can be viewed below and is also available on YouTube here.

Center Director Dr. Maureen Hanson will be presenting current scientific research on ME/CFS during a panel session hosted by New York State Department of Health (NYS DOH). The session titled “Scientific Research on Myalgic Encephalomyelitis/Chronic Fatigue Syndrome in the Age of COVID-19” will be moderated by Dr. Charles Gonzalez. Dr. Ian Lipkin (Columbia University) and Dr. Avindra Nath (NIH) will be joining Hanson as panel presenters.
UPDATE: In case you missed the panel discussion, NYS DOH released a recording along with each presenter’s slides. Direct links to the recording and Dr. Hanson’s slides are below. Visit the NYS DOH ME/CFS website for more information.
Jessica Maya, a graduate student in the Genetics, Genomics, and Development Program at Cornell University in Maureen Hanson’s lab, talks about ME/CFS, the immune system response, and the fuels that energize immune cells to properly defend the body. This talk was adapted from Cornell University’s 3 Minute Thesis Finalists Round Competition, where she was tasked to explain her thesis work in under 3 minutes in an engaging form that could be understood by an intelligent audience with no background in the research area.
For the ME International Awareness Day, Director Maureen Hanson is providing a Pecha Kucha on ME/CFS. This is a short video presentation in which 20 slides are presented, automatically changing every 20 seconds. This format has been developed to convey information quickly in a visual manner (see https://www.pechakucha.com/ for more information).
IACFSME held a virtual medical and scientific research conference on July 27-30, 2022. Our Center presented several talks and participated in the poster session at the conference. Center members Andrew Grimson, Arnaud Germain, Betsy Keller, Geoff Moore, Jessica Maya, and Katie Glass gave oral presentation on topics ranging from immune cell exhaustion to post CPET recovery. Postdoctoral associate, Ludovic Giloteaux, presented a poster on extracellular vesicle proteins in plasma. Details about the conference agenda can be found on the event’s website.
We would also like to announce that Candace Receno, a new collaborator at Ithaca College, and Jessica Maya received the NIH NINDS travel award at this year’s meeting. Congratulations to Candace and Jessica!
The Massachusetts ME/CFS & FM Association held their annual meeting on Oct. 23, 2021. The meeting’s title, Advances in Our Understanding of ME/CFS and the Effects of Long COVID, highlights the theme of this event. Dr. Maureen Hanson, Center Director, was invited to speak at this meeting. Hanson’s talk provided a summary of ongoing work at the ENID Center. Mass ME/CFS & FM has uploaded the talks from this meeting to YouTube. You can watch Hanson’s full talk below, and the complete playlist of all talks from the meeting can be found here.
Maureen Hanson, Center Director, and Betsy Keller, Clinical Core Co-lead, presented at the Beyond the Symptoms: The Biology of Fatigue workshop. The workshop was co-sponsored by the NIH Neuroscience Blueprint Research Program and Sleep Research Society, and it took place on September 27-28, 2021. Hanson provide insight into fatigue from the perspective of immune dysfunction in ME/CFS. Keller drew from her experience in exercise physiology to elaborate on post-exertional malaise in ME/CFS.
Detailed meeting information including the agenda can be found on the event website. Recordings of the meeting are freely available on NIH VideoCast for Day 1 and Day 2, separately.
