Immunologic checkpoint expression on murine effector and memory T-cell subsets

Satoshi Nemoto, Adam W. Mailloux, Jodi Kroeger, James J. Mulé Cytometry PART A, Volume 89, Issue 5, 427–429 (2016)

PURPOSE: This panel was designed to assess the expression levels of cell surface inhibitory receptors known as “immune checkpoints” within the context of multiple naïve, activated, memory, and effector phenotypes among T-cells for subsequent adoptive transfer using the CD45.1/CD45.2 congenic system in C57BL/6 mice. It can be easily adapted to other congenic systems, or may be used without any congenic marker. While many panels have been published that analyze T-cell activation, memory phenotypes, or effector differentiation states, few, if any, are comprehensive enough to assess these compartments simultaneously while measuring inhibitory immune checkpoint receptor expression. The ability to do so within a congenic system creates a powerful tool for investigating the evolution of T-cell based immune responses in a broad range of contexts. Here, the panel is used to analyze the T-cell compartment in normal spleen, or T-cells infiltrating subcutaneous murine colon adenocarcinoma, MC38. However, any murine source of T-cells would serve as an appropriate sample source for this panel.
