Mast cell recruitment is modulated by the hairless skin microbiome

J Allergy Clin Immunol. 2019 Jul;144(1):330-333.e6. doi: 10.1016/j.jaci.2019.02.033. Epub 2019 Mar 27.

Abstract

Hairless mice have countless mast cells (MCs) in the skin and a more gram positive microbiome (GPM). MC number normalizes when TLR2, a GPM sensor, is deleted, proving a connection between hair-loss, GPM and MCs.
