Cytotoxic T cells and immunotherapy

Abstract

Promising immunotherapies for viral infections and malignancies reflect the successful, rapid translation of laboratory findings into clinical practice. Fletcher et al. [1] present imaging studies of Epstein-Barr virus (EBV)-associated lymphomas before and after immunotherapy. Here, we briefly review the scientific bases of such novel therapies, which have evolved from advances in understanding of immune effector cells, of the cytokines that drive immune responses, and of the mechanisms underlying cell death.
