Unlocking the Intricacies of Gamma-Delta T Cells

Gamma-delta T cells represent a distinctive subset within the T cell family, and their implications in cancer have been under rigorous investigation. A recent study, led by PILOT member Sagar, involved researchers from Freiburg University Medical Center and Institut Curie, shedding light on the diversity and tissue residency of gamma-delta T cells across various organs in mice. 


The study utilized cutting-edge multimodal single-cell profiling approaches to reveal distinct populations of γδ T cells across organs. γδ T cells in the skin and intestine were found to exhibit epigenetic hallmarks of functional plasticity. Insights into tissue residency features were gained through parabiosis experiments, demonstrating tissue-specific residency characteristics unique to γδ T cell subsets. Unlike other lymphocyte lineages such as tissue-resident memory CD8+ T cells and natural killer T cells, gamma-delta T cells do not share a universal transcriptional program of tissue residency defined by Hobit and Blimp1 across organs. However, genome-wide transcriptional hallmarks of tissue-resident γδ T cells are analogous to all other tissue-resident lymphocytes. The study's findings have been published in Nature Immunology and are available here:
