GZMB and HIV infectious disease: These analyses included determining the expression of granzyme B (GrzB) (cytotoxicity), Ki67 (cell cycling), CXCR3 (effector T cell trafficking and function), α4β7 (gut-homing receptor associated with HIV infection) (66, –, 68), and major histocompatibility complex class II (MHC-II) (T cell activation) and showed no differences among animals in the vaccine or control groups (Fig. S1).
