Gut Microbes May Up PD-1 Inhibitor Response

No authors listed. Cancer Discov. 2017 May.

Abstract

Confirming the results of animal studies, new research shows that the composition of patients' microbiome influences their response to checkpoint inhibitors. Patients with melanoma who benefit from PD-1 inhibitors carry a greater variety of species and higher numbers of microbes in the Clostridiales group. Increased abundance of certain bacteria in this group also correlated with higher numbers of CD8+ T cells in patients' tumors.
