Tumor-derived exosomes induce CD8+ T cell suppressors
2 Aug 2017
Abstract excerpt
Background The suppressive nature of immune cells in the tumor microenvironment plays a major role in regulating anti-tumor immune responses. Our previous work demonstrated that a soluble factor from tumor cells is able to induce a suppressor phenotype (SP) in human CD8+ T cells typified by loss of CD27/CD28 expression and acquisition of a potent suppressor function. The present study hypothesized that the...
