Abstract:Immune checkpoint inhibitors blocking the interaction between PD-1 and PD-L1 are revolutionizing the cancer immunotherapies with durable clinical responses. Although high expression of PD-L1 in tumor tissues has been implicated to correlate with the better response to the anti-PD-1 therapies, this association has been still controversial. In this study, to characterize immune microenvironment in tumors, we examined mRNA levels of immunerelated genes and characterized T cell repertoire in the tumors of 13 melan… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
