摘要: This chapter focuses on purinergic neurotransmission and nucleotide receptors. The proportions of ATP noradrenaline (NA) vary in different tissues species, during development ageing pathophysiological conditions. Acetylcholine (ACh) are cotransmitters parasympathetic nerves supplying the urinary bladder. Purinergic signaling brain stem is involved control autonomic functions, including cardiovascular respiratory regulation hormone secretion body temperature at hypothalamic level. nucleus tractus solitarius (NTS) a major integrative center reflex system; stimulation P2X receptors NTS evokes hypotension. Adenoviral expression P2X1 receptor-green fluorescent protein construct vas deferens shows receptor to be localized clusters, with larger ones apposing nerve varicosities. formation oligomers by P2Y likely widespread greatly increase diversity signaling. often expressed same cells as Thus, there possibility bidirectional cross-talk between these two families nucleotide-sensitive © 2012 Elsevier Inc.
