Macrophages activated via the IL-4 receptor possess non-immune functions that support tissue homeostasis, but their specific role in aging is unknown. In this issue of Immunity, Zhou et al. show that IL-4 extends lifespan by inducing DNA repair pathways that protect macrophages from cellular senescence. Copyright © 2024 Elsevier Inc.
