PTH induces bone loss via microbial-dependent expansion of intestinal TNF+ T cells and Th17 cells

Abstract

T cells are involved in the bone loss induced by parathyroid hormone (PTH), but their origin is unknown. Here, the authors show that the intestinal microbiota is required for PTH to induce bone loss and describes mechanisms for microbiota-mediated gut–bone crosstalk in mouse models of hyperparathyroidism.
