Breaking up the CD8+ T cell: Treg pas de deux

Cancer Cell. 2024 Jun 10;42(6):941-942. doi: 10.1016/j.ccell.2024.05.016.

Abstract

Checkpoint blockade immunotherapies, such as anti-programmed death-1 (PD-1), unleash anti-tumor CD8+ T cell responses but may also induce immunosuppressive regulatory T cells (Tregs). In this issue of Cancer Cell, Geels et al. uncover that anti-PD-1 leads to Treg expansion via interleukin-2 (IL-2)-producing CD8+ T cells. Combining anti-PD-1 with anti-ICOSL interrupts this crosstalk, thereby enhancing tumor control.
