Abstract

Immune-related adverse events (irAEs) occur in almost every organ system in a seemingly unpredictable fashion, causing substantial morbidity and mortality. Lozano et al.1 report peripheral blood profiling from patients receiving immune checkpoint inhibitors, identifying that diverse CD4+ effector memory T cells present prior to treatment are associated with severe irAEs.
