Fig. 4From: PD-1 deficiency promotes TFH cells expansion in ITV-immunized mice by upregulating cytokines secretionMCP-1, IFN-γ and IL-10 were significantly elevated in the serum of ITV-immunized PD-1-/- mice. Serum samples were collected from immunized WT (n = 5) and PD-1-/-mice (n = 5) at the indicated times after the final immunization and the concentrations of cytokines were measured serially by a CBA. Three individual experiments were performed. The data are presented as the mean ± SD. Data were compared with the two-way ANOVA. Abbreviation: n, number of samplesBack to article page
