Fig. 3From: A radioenhancing nanoparticle mediated immunoradiation improves survival and generates long-term antitumor immune memory in an anti-PD1-resistant murine lung cancer modelFlow cytometry analysis of CD4+ T cells, CD8+ T cells, and regulatory T cells (Tregs, labeled with CD4+FoxP3+) in the secondary tumors, harvested on day 16. A CD4+ T cell/CD45+ cell ratio. B CD8+ T cell/CD45+ cell ratio. C Treg CD4+FoxP3+ cell/CD45+ cell ratio. D CD8+ T cell/Treg CD4+FoxP3+ cell ratio. E Density of CD4+ T cells. F Density of CD8+ T cells. G Density of Treg CD4+FoxP3+ cells. Data are expressed as means ± standard error of the mean (SEM). P < 0.05 was considered statistically significant. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, NS not significant.
