When the expressions of these receptors were examined, significant decrease in the expression of CD127+ was observed on most subsets of CD8+ T cells from the CFS/ME patients while in the MS patients, CD127 expression was reduced on naïve, EM, and EMRA subsets of CD8+ T cells in the CFS/ME patients (Figure 2(b)). Here, CD8A is linked to myeloid sarcoma.
