<prompt> Iqembu lakhe lathola ukuthi uma lisebenze yi-ATP ama-astrocyte angakhipha i-glutamate ngokusebenzisa ama-pores akhiwe kuma-receptors e-P2X7.  <response>: Yiqiniso, inguqulo eyinkimbinkimbi yalesi sigwebo ithi Iqembu lakhe lathola ukuthi lapho ivuselelwa i - ATP ama - astrocytes angakhipha i - glutamate ngokusebenzisa ama - pore akhiwe kuma - P2X7 receptors; imisebenzi ye - neuronal ingavinjelwa nge - heterosynaptically yi - glia - ekhipha i - ATP futhi le - ATP ikhululwa nge - exocytosis yama - lysosomes.
