Atrial and ventricular rat coronary arteries are differently supplied by noradrenergic, cholinergic and nitrergic, but not sensory nerve fibres

The present immunohistochemical study set out to determine the extent of perivascular
innervation in the rat heart, using markers for noradrenergic sympathetic fibres (tyrosine
hydroxylase= TH), cholinergic parasympathetic fibres (vesicular acetylcholine transporter=
VAChT), nitrergic fibres (neuronal NO synthase= nNOS), and peptidergic sensory fibres
(calcitonin gene-related peptide= CGRP). For each of these antigens, the vascular
innervation density was assessed separately in the atria, the basal and the apical parts of�…
