CCR5 and myeloid sarcoma: Once again, we set out to investigate whether these observations were MAIT cell-specific, or shared by non-MAIT memory cells, and found that MAIT cells from MS patients expressed CCR5, CCR6, and CXCR6 at higher levels than non-MAIT cells, with greater expression during exacerbations (p < 0.05 to p < 0.001; Supplementary Figures S2A–C).
