Gamma-delta T cells implicated in innate-like surveillance of early cancer
Start here
An ImmuneZoom expert lecture examined the non-classical roles of gamma-delta T cells and their T cell receptors in innate-like immunity, including lymph node stress surveillance that detects subtle cellular changes capable of preceding cancer. Drawing on evolutionary comparisons across vertebrates and the VLR systems of jawless fish, the talk asked why energetically costly diversified antigen receptor generation has been retained through evolution. Tumor experiments presented in the lecture showed that mice lacking gamma-delta T cells develop more papillomas and carcinomas after induction, supporting a role for these cells in epithelial tumor surveillance. The 55-minute talk, delivered as a YouTube expert interpretation, frames gamma-delta T cells as a component of early cancer detection rather than only adaptive effectors.
