A cell-engineered system to assess tumor cell sensitivity to CD8+ T cell-mediated cytotoxicity

Oncoimmunology. 2019 Apr 26;8(8):1599635. doi: 10.1080/2162402X.2019.1599635. eCollection 2019.

Abstract

In vitro assays that evaluate CD8+ T cell-mediated cytotoxicity are important to aid in the development of novel therapeutic approaches to enhance anti-tumor immune responses. Here, we describe a novel cytotoxicity co-culture assay that circumvents the problem of highly variable allogeneic responses and obviates the constraints of HLA-restriction between effector and target cells. We show that this assay can be easily applied to a panel of tumor cell lines to provide additional insights into intrinsic drivers of sensitivity/resistance to T cell-mediated killing, and to evaluate the impact of targeted therapies on both tumor and T cell compartments.

Keywords: T cell; cytotoxicity; immuno-oncology; immunotherapy.
