“…SC express the α2 and 3, β1, 2, 3 and γ2 subunits ( Melcangi et al, 1999a ; Magnaghi et al, 2006a ), as well as the α4 and δ subunits, more characteristic of the extrasynaptic receptor ( Faroni et al, 2019 ). In addition, we found most of these subunits in the mouse DRG neuronal cultures, with predominant expression of the synaptic subunits α1, α2, β1, β3, γ2 ( Faroni et al, 2019 ). In general, in the PNS, the role of ALLO through GABA-A receptor has been widely characterized in the glial compartment, showing enhancement of SC proliferation, motility, differentiation and myelination ( Figure 2 ; see also the following chapter).…”
