Heterogeneity of axon terminals expressing VGLUT1 in the cerebral neocortex.


Using immunocytochemical techniques and confocal microscopy we have studied the localization of the vesicular glutamate transporters (VGLUTs) 1 and 2 in the mammalian cerebral cortex. The cardinal observations gathered to date can be summarized as follows: 1) Many VGLUT1-positive puncta coexpressing synaptophysin-1 outline pyramidal cell somata and proximal dendrites; of these, a sizeable fraction coexpress VGAT, the vesicular transporter for GABA; 2) VGLUT2-positive puncta are also present in layers II-III and some of them coexpress VGLUTI. These findings suggest that in the cerebral cortex of adult rats axon terminals expressing VGLUT1 are heterogeneous.
