Accordingly, proteomics following fear conditioning in mice, showed that new translation influences peri-synaptic astrocyte protein composition in vivo under physiological conditions. Webglia–synaptic interaction are the peripheral astrocyte processes (PAPs [6]). These processes extend from the glial main processes, which contain glial fibrillary acidic protein (GFAP) positive glial filaments, and can be very small, down to the dimensions of pure membrane appositions (50–100 nm).
