WebNov 1, 2012 · Because of similar phenotypic expression between normal hepatocytes and Hepa1-6 cells, cytotoxic T lymphocytes (CTLs) recognizing shared antigen between them are induced by immunization of mice with DCs loaded with Hepa1-6 [24]. WebCancer-associated fibroblasts (CAFs), macrophage type 2 (M2) cells, and regulatory T cells (Tregs) could make immunologic barriers against CD8 + T cell-mediated antitumor immune responses. Thus, CD8 + T cells are needed to be primed and activated toward effector CTLs in a process called tumor immunity cycle for making durable and efficient ...
