IFNG and myeloid sarcoma: In total γδ T cells, IL-17A or IFN-γ production by Vδ1+ γδ T cells was comparable between MS patients and HCs, whereas the percentages of IFN-γ+Vδ2+ and IL-17A+IFN-γ+Vδ2+ γδ T cells were significantly lower in MS patients than in HCs (pcorr < 0.0005 and pcorr = 0.0135, respectively).
