CDK4/6 inhibition promotes anti-tumor immunity through the induction of T cell memory.

Cancer Discov 2021 May 14. Epub 2021 May 14.

Gene Regulation Laboratory, Cancer Therapeutics Program, Peter MacCallum Cancer Centre.

Pharmacological inhibitors of cyclin dependent kinases 4 and 6 (CDK4/6) are an approved treatment for hormone receptor-positive breast cancer and are currently under evaluation across hundreds of clinical trials for other cancer types. The clinical success of these inhibitors is largely attributed to well-defined tumor-intrinsic cytostatic mechanisms, while their emerging role as immunomodulatory agents is less understood. Using integrated epigenomic, transcriptomic and proteomic analyses, we demonstrated a novel action of CDK4/6 inhibitors in promoting the phenotypic and functional acquisition of immunological T cell memory.
