Role of nitric oxide synthase in human sweat gland output

Abstract

The contribution of nitric oxide synthase (NOS) to the process of cholinergic-mediated human eccrine sweat production is unclear. Using a novel model for cholinergic-mediated sweating in humans, I demonstrate that blocking the NOS system led to a reduction in local sweat rate (LSR). This reduction in LSR was maintained in the presence of K+ channel blockade with tetraethylammonium.
