Breast duct mucosal associated invariant T (MAIT) cells show altered Vβ chain use frequencies compared with blood MAIT cells. a Flow cytometric staining to detect use of the indicated sets of Vβ chains by MAIT cells from blood (left panel) vs. breast duct (right panel). b Quantification of the fraction of MAIT cells staining positively for the indicated Vβ chains in peripheral blood mononuclear cells (PBMCs) or breast duct tissues obtained from female subjects. Each symbol represents the result from a different tissue donor. PBMCs and breast tissue samples were not obtained from the same donors. TCR T-cell receptor
