WebAbstract Adenosine 5'-triphosphate (ATP) is released as a genuine co-transmitter, or as a principal purinergic neurotransmitter, in an exocytotic and non-exocytotic manner. It activates ionotropic (P2X) and metabotropic (P2Y) receptors which mediate a plethora of functions in the brain. WebOct 10, 2024 · Calcium-triggered exocytotic release of neurotransmitters and hormones from neurons and neuroendocrine cells underlies neuronal communication, motor activity and endocrine functions. The core of the neuronal exocytotic machinery is composed of soluble N-ethyl maleimide sensitive factor attachment protein receptors (SNAREs). …
