Additionally, activated microglia can release cytokines and cytotoxic factors that accelerate the occurrence or deterioration of neurodegenerative diseases [74], and promote the proliferation of astrocytes, glial fibrillary acidic protein, and some other cytokines that contribute to the enhancement of the glia scar, which has major effects on neuronal excitability and secondary pathologies, such as epilepsy [75,76]. The gene discussed is GFAP; the disease is epilepsy.
