Immunoreactivity for GABA, GAD65, GAD67 and Bestrophin-1 in the Meninges and the Choroid Plexus: Implications for Non-Neuronal Sources for GABA in the Developing Mouse Brain
Figure 5
Bestropin-1 (Best1), a GABA-permeable channel, is expressed in the meninges and the choroid plexus.
(A) The faint signals for Best1 were ubiquitously detected in the cells in the E14.5 neocortical structures including GAD65/67-positive meninges. (B) The cells in the choroid plexus epithelium exhibited rather strong signals for Best1 on E14.5. Me, meninge; MZ, marginal zone; CP, cortical plate; SP, subplate, CPe, choroid plexus epithelium: CPm, choroid plexus mesenchyme: Bars, 50 µm.
