Abstract

The link between the gut microbiome and responsiveness to immune checkpoint inhibitor (ICI) therapy is now well established. New therapeutic opportunities exploiting this relationship are being developed with the goal of augmenting ICI efficacy. In this review, we summarize the foundational research establishing these interactions and discuss the mechanisms and novel therapeutic options associated with this gut microbiome-ICI connection.
