One size might fit all: Indole-3-propionic acid potentiates pan-cancer immunotherapy.

ABSTRACT

Microbial-based therapies have the potential to combat immunotherapy resistance, extending the boundaries of oncological therapeutics. In a recent issue of Cell, Jia et al. demonstrates an example of microbial collaboration to produce a postbiotic that promotes the stemness program of CD8+ T cells to augment immunotherapy at the pan-cancer level.
