Cytokines in the cerebrospinal fluids of patients with chronic fatigue syndrome/myalgic encephalomyelitis.
Peterson, D, Brenu, E W, Gottschalk, G et al.·Mediators of inflammation·2015
Researchers tested cerebrospinal fluid (the fluid around the brain and spinal cord) from ME/CFS patients and healthy controls to see if immune chemicals called cytokines were different. Out of 27 different immune chemicals tested, they found that only one—called IL-10—was lower in ME/CFS patients. This suggests that immune system problems in the brain and nervous system may play a role in ME/CFS symptoms.
