Candida albicans can enter skeletal tissue through a skin wound in an immunocompromised host or by contamination during orthopedic surgery. Such Candida osteomyelitis is accompanied by severe pain and bone destruction. It is established that nociceptor innervation occurs in skin and bone, but the mechanisms of nociceptive modulation in fungal inflammation remain unclear. In this study, we show that C. albicans stimulates Nav1.8-positive nociceptors via the beta-glucan receptor Dectin-1 to induce calcitonin gene-related peptide (CGRP). This induction of CGRP is independent of Bcl-10 or Malt-1 but dependent on transient receptor potential cation channel subfamily V member 1 (TRPV1)/transient receptor potential cation channel subfamily A member 1 (TRPA1) ion channels. Hindpaw beta-glucan injection after av1.8-positive nociceptor ablation or in TRPV1/TRPA1 deficiency showed dramatically increased osteoinflammation accompanied by impaired CGRP production. Strikingly, CGRP suppressed beta-glucan-induced inflammation and osteoclast multinucleation via direct suppression of nuclear factor-kappa B (NF-kappa B) p65 by the transcriptional repressor Jdp2 and inhibition of actin polymerization, respectively. These findings clearly suggest a role for Dectin-1-mediated sensocrine pathways in the resolution of fungal osteoinflammation.
