Cancer Cells Go Incognito to Cause Therapy Relapse

“In a recent study released in Cell, Agudo explained her teams efforts to comprehend the aspects that contribute to breast cancer treatment regression.1 The scientists hunted for immunotherapy-resistant cells and sought to comprehend how they prevented immune cell attack by utilizing the power of Jedi T cells,2 which specifically target and damage cells revealing green fluorescent protein (GFP). By injecting the Jedi cells into mice that reveal GFP, Agudo isolated and imagined cancer cells that endured the T cell attack.Using a mouse model of mammary cancer, Agudo found that the Jedi cells eliminated most GFP cancer cells, but some remained clustered within tumors. They isolated the photoconverted cells, which included cancer cells, immune cells, and helpful fibroblasts, and performed scRNA-seq once again.”References P.
