P2Y1 receptor-evoked glutamate exocytosis from astrocytes: control by tumor necrosis factor-alpha and prostaglandins.
Domercq M, Brambilla L, Pilati E, Marchaland J, Volterra A, Bezzi P. Domercq M, et al. Among authors: volterra a. J Biol Chem. 2006 Oct 13;281(41):30684-96. doi: 10.1074/jbc.M606429200. Epub 2006 Aug 1. J Biol Chem. 2006. PMID: 16882655
The process in situ displays characteristics resembling those in cultured astrocytes and is distinctly different from synaptic glutamate release evoked by high K+ stimulation as follows: (a) it is sensitive to cyclooxygenase inhibitors; (b) it is deficient in preparations …
