CD4 and myasthenia gravis: Among the MG patients and normal controls (NCs) (n = 25), including 13 MG patients and 12 NCs, we found significant differences in anti-AChR Ab titer (p < 0.001), IL-7 (p < 0.001), IL-10 (p = 0.005) and IFN-γ (p = 0.007), but not in age, sex, FoxP3+ Treg/CD4+T ratio, Tr1 Treg/CD4+T ratio, Tr1/FoxP3+ Treg ratio, TGFβ1 and IL-6 titer, between MG patients and normal individuals.
