Highlights of 2024: γδ T cells and bad blood.

In this manuscript for the "Highlights of 2024" series, this is me trying to summarize recent discoveries regarding the emerging regulatory and effector roles of γδ T cells during sepsis, both in human patients and in mouse models. The new findings not only aid our understanding of key immunological and pathophysiological pathways that hit differently during the course of the disease but may also have clinical relevance for a life-threatening condition that requires swift intervention and tailored patient management.
