| Abstract: | Objective To observe the distribution of P2X4 receptor in the rat nervous system. Method Immunocytochemical staining technique by using specific antibody against P2X4 receptor.Results P2X4 receptor immunoreactive neuronal cell bodies were observed in the olfactory bulb, anterior cingulate cortex, piriform cortex, medial septa nucleus, central amygdaloid nucleus, hippocampal CA3 field, supramammillary nucleus, interpeduncular nucleus, mesencephalic trigeminal nucleus, trigeminal motor nucleus, solitary tract nucleus, area postrema, subfornical organ, Purkinje cell layer of the cerebellar cortex, laminae Ⅰ and Ⅱ of the medullary and spinal dorsal horn, dorsal root ganglion and trigeminal ganglion. Conclusion The present results indicate that P2X4 receptor immunoreactive structures are widely distributed in the rat nervous system. These P2X4 receptors provide the functional sites for ATP. |
