WebCAR T cells acquired BCMA by trogocytosis, and BCMA on MM cells was rapidly internalized. Since BCMA can be re-expressed during progression and persisting CAR T cells may not protect patients from relapse, we investigated whether non-functional CAR T cells play a role in tumor progression.

WebNov 24, 2024 · Trogocytosis is a process of membrane fragment transfer between two cells in contact. This term trogo is derived from ancient Greek meaning “gnaw.” Previous studies have identified Entamoeba histolytica, Francisella tularensis, microglia, and immune cells as trogocytic ( 3 – 7 ). WebSnippet: Trogocytosis is a fast, cell-cell contact-dependent uptake of membrane patches and associated molecules by one cell from another. Here, we report our investigation of trogocytosis of TYRO3, a cell membrane protein, from tumor target cells to natural killer (NK) cells and the associated functional consequences for NK cells. chris disney
