The Scientist - Investigating Targeted CD3 Activation in Cytotoxic T cells via Immune Checkpoint Inhibition
Kristin Fino, Frederick National Laboratory for Cancer Research
Immune checkpoint inhibitors promote anti-tumor immune responses by enhancing T-cell activity. Measuring the pharmacodynamic effects of these drug types presents a challenge as both the immune and cancer cell populations must be separated and assessed individually. Using a quantitative multiplex immunofluorescence assay (mIF) allows for in-depth cell phenotype characterization and spatial context. Researchers at Frederick National Laboratory for Cancer Research developed a robust mIF assay with InSituPlex® technology to better investigate T-cell activation states within the tumor microenvironment and across multiple patient tumor biopsies.
