abstract：UNLABELLED:J. Neurochem. (2012) 121, 597-606. ABSTRACT:In cultured rat neocortical interneurons, we have studied the effect of long-term application of NMDA or AMPA on the surface density of the NMDA (GluN) receptor subunits GluN1 and GluN2B. Stimulation of Ca(2+) -permeable AMPA (GluA) receptors located on the intern...

abstract：:The extension of microglial processes toward injured sites in the brain is triggered by the stimulation of the purinergic receptor P2Y(12) by extracellular ATP. We recently showed that P2Y(12) stimulation by ATP induces microglial process extension in collagen gels. In the present study, we found that a P2Y(12) agonis...
