Abstract
The muscarinic cholinergic receptor of rat eccrine sweat gland was characterized using quantitative autoradiography and [3H]QNB as radioligand. The distribution of radioligand was maximal in the secretory coil. Autoradiographic competition binding studies were performed using selective antagonists to M1 (pirenzepine), M2 (AF-DX 116), and M3 (4-DAMP) and the classical nonselective antagonist atropine. pKi for pirenzepine, AF-DX 116, 4-DAMP, and atropine was 6.58, 5.47, 8.50, and 8.66 respectively indicating that the eccrine sweat gland muscarinic receptor was predominantly M3.Entities:
