Interestingly, we have identified eight proteins encoded by MS susceptibility genes (LCK, GRAP2, CD5, ZC3HAV1, SAE1, EPPK1 and CD6 in CD4+ T cells and TNFAIP8 in CD8+ T cells), which are more abundant in T cells from MS patients compared to healthy controls. Here, TNFAIP8 is linked to myeloid sarcoma.
