WebOverview. Regulatory T (Treg) cells are a subset of CD4 + T cells that is involved in maintaining immune homeostasis and self-tolerance by inhibiting the pro-inflammatory … WebJan 8, 2024 · The results of this study show that by using anti-PD-1 antibody, the proportion of Foxp3 + T cells in CD4 + cells and Ki-67 + cells in Foxp3 + T cells decreases. This suggests that the administration of anti-PD-1 antibody eliminates effector Treg expressing PD-1 among Foxp3 + T cells.
WebMar 3, 2010 · Depletion of CD4 + CD25 + FoxP3 + Treg using PC61 mAb (anti-murine CD25 rat IgG1) is widely used to characterize Treg function in vivo.However, the mechanism of Treg depletion remains largely unknown. Herein, we report the PC61 mAb's mechanism of action.
