As shown in Figure 3, the percentage of CD4+CD25+Foxp3+ cells among CD4+CD25+ cells, in the spleens of MuSK-EAMG mice (Figures 3B,C) is lower when compared to the percentage of such cells from healthy adjuvant-immunized controls (Figures 3A,C) These findings suggest that alterations in the Treg cell population may be involved in the immunopathology of MuSK-MG. This evidence concerns the gene FOXP3 and myasthenia gravis.
