GD3 ganglioside checkpoints in immune surveillance of senescent cells

Abstract

Iltis, Moskalevska and colleagues investigate how the innate immune system regulates the age-related accumulation of senescent cells. They show that upregulation of the GD3 ganglioside-based immune checkpoint enables senescent cells to evade immune surveillance mediated by natural killer cells during aging, and that targeting GD3 is protective in age-related disease.
