Distinct phenotypic states and spatial distribution of CD8+ T cell clonotypes in human brain metastases
27 Apr 2022
Abstract excerpt
Metastatic disease in the brain is difficult to control and predicts poor prognosis. Here, we analyze human brain metastases and demonstrate their robust infiltration by CD8 + T cell subsets with distinct antigen specificities, phenotypic states, and spatial localization within the tumor microenvironment. Brain metastases are densely infiltrated by T cells; the majority of infiltrating CD8 + T cells express PD-1....
