A new publication from the Center on fatty acid oxidation in immune cells has appeared today. Jessica Maya is the lead author of Altered Fatty Acid Oxidation in Lymphocyte Populations of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome published in the International Journal of Molecular Sciences.

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.
