Aberrant inducible T-cell costimulator (ICOS) and programmed death 1 (PD-1) expression on follicular T helper (Tfh) cells isolated from murine gammaherpesvirus 68 (MHV68) -infected or regulatory T-cell-deficient mice. Representative cytometric analysis of ICOS and PD-1 levels on CD4+ CXCR5+ (Tfh) cells, splenocytes isolated from C57BL/6 mice 14 days post-infection with wild-type MHV68 (infected) or UV-inactivated MHV68 (control) or Foxp3DTR mice treated with diphtheria toxin for 12 days. Data are representative of a minimum of two independent experiments with a minimum of three mice per group per experiment.
