Checkpoint Molecule Profiling in Tumor and Immune Cell Lines: Applications for Immuno-oncology Drug Screening Webinar

April 21, 2022, at 12:00 PM ET


Modulating immune checkpoints is a promising approach for unleashing the potential of the anti-tumor immune response; however, cancer biologists need comprehensive data on the expression levels of checkpoint molecules for different cancer types to guide specific drug development plans. ATCC’s vast portfolio can be tapped by scientists to yield these essential checkpoint expression data. In this webinar, we present checkpoint protein profiling of T cell lines and tumor cell lines from various cancer types. He then shows the responses of the cell lines to several immunotherapies in a co-culture assay system with a human CD4+ T cell line and primary CD8+ T cells, demonstrating a unique and effective approach for checkpoint assay development.

Key Points

  • Cancer biologists need physiologically relevant cell models to develop cancer immunotherapies
  • ATCC’s vast portfolio of human tumor and immune cell lines was tapped to yield essential immune checkpoint expression data
  • The endogenous expression of checkpoint molecules on the surface of tumor cells is comparable to patient samples
  • Over 60+ tumor cell lines have been profiled for established and novel checkpoint molecules
  • Checkpoint protein profiling of T cell lines and tumor cell lines provides a valuable tool in the screening of biologics as cancer immunotherapy treatment
