Purinergic receptors in microglia: functional modal shifts of microglia mediated by P2 and P1 receptors.

abstract：:Reorganization of the adult dentate gyrus following unilateral entorhinal cortex lesion (ECL) is a well-established model for studying mechanisms of trauma-induced neuronal plasticity. The lesion induces deafferentiation of the outer molecular layer, which is accompanied by a strong astroglial reaction. This glial res...
