Alterations in peripheral blood CD8⁺T cell phenotypes and receptors in controls, moderate and severe CFS/ME. a CD45RA effector memory, naïve, central memory and effector memory CD8⁺T cell phenotypes represented as percentage of total CD8⁺T cells (%). b LFA-1 expression in central memory CD8⁺T cells for control, moderate CFS/ME and severe CFS/ME participants. c KLRG1 expression in total CD8⁺T cells for control, moderate CFS/ME and severe CFS/ME participants. All data are represented as mean ± SEM. * represents results that were significantly different where p <0.05. CFS/ME: Chronic Fatigue Syndrome/Myalgic Encephalomyelitis; LFA-1: lymphocyte function-associated antigen 1; KLRG1: killer cell lectin-like receptor subfamily G member 1; SEM: Standard Error of the Mean
