Immunohistochemical evidence for species-specific coexistence of catecholamines, serotonin, acetylcholine and nitric oxide in glomus cells of rat and guinea pig aortic bodies
The aortic bodies act as arterial chemoreceptors. Endogenous sources of Ach, catecholamines, NO and serotonin, were studied by means of immunohistochemistry within rat and guinea pig aortic bodies.
