Primary hyperparathyroidism (PHPT) is a common cause of bone loss that is modeled
by continuous PTH (cPTH) infusion. Here we show that the inflammatory cytokine
IL-17A is upregulated by PHPT in humans and cPTH in mice. In humans, IL-17A is
normalized by parathyroidectomy. In mice, treatment with anti-IL-17A antibody and
silencing of IL-17A receptor IL-17RA prevent cPTH-induced osteocytic and
osteoblastic RANKL production and bone loss. Mechanistically, cPTH stimulates
conventional T cell production of TNF? (TNF), which increases the differentiation
of IL-17A-producing Th17 cells via TNF receptor 1 (TNFR1) signaling in CD4(+)
cells. Moreover, cPTH enhances the sensitivity of naive CD4(+) cells to TNF via
G?S/cAMP/Ca(2+) signaling. Accordingly, conditional deletion of G?S in CD4(+)
cells and treatment with the calcium channel blocker diltiazem prevents Th17 cell
expansion and blocks cPTH-induced bone loss. Neutralization of IL-17A and calcium
channel blockers may thus represent novel therapeutic strategies for
hyperparathyroidism.
