Chronic lymphocytic leukaemia cells become both activated and immunosuppressive following interaction with CD3 and CD28 stimulated PBMC
چکیده انگلیسی
Chronic lymphocytic leukaemia (CLL) is associated with immunosuppression. The activation of CLL cells induced by interaction with other cell types, particularly activated T-cells, within the tumour micro-environment is thought to be important for CLL progression. However it is unclear whether activated CLL cells (CLLAct) have immunosuppressive capacity. We report that co-culture of CLL cells with normal PBMC in the context of CD3/CD28 T-cell activation generates CLLAct with increased CD38 expression that are capable of suppressing the proliferative responses of both CD4+ and CD8+ T-cells. The suppression required cell contact but did not involve induction of T-cell apoptosis.
