Part of a series on Purinergic signalling Simplified illustration of extracellular purinergic signalling Concepts Purinergic signalling Receptors Pannexins Ectonucleotidases Metabolism Membrane transporters Nucleoside transporters Concentrative Equilibrative v t e Purinergic receptors , also known as purinoceptors , are a family of plasma membrane molecules that are found in almost all mammalian tissues. [1] Within the field of purinergic signalling, these receptors have been implicated in learning and memory, locomotor and feeding behavior, and sleep. [2] More specifically, they are involved in several cellular functions, including proliferation and migration of neural stem cells, vascular reactivity, apoptosis and cytokine secretion. [2] [3] These functions have not been well characterized and the effect of the extracellular microenvironment on their function is also poorly understood. The term purinergic receptor was originally introduc
