Astrócitos: ação e interação no Sistema Nervoso
Resumo
Os astrócitos, juntamente com os oligodendrócitos e a micróglia, fazem parte do tecido de neuroglia que acompanha os neurônios. Devido à importância e aos avanços nesta área, propõe-se esta revisão bibliográfica, a qual foi realizada através da busca por “astrócitos” em revistas relacionadas a neurociências a nível celular e molecular como “Glia, Cells, Neuron”, dos últimos cinco anos (2018-2023), com o objetivo de compilar informações sobre a estrutura e função dessas células gliais. É abordada a evolução da glia, os tipos de astrócitos e a estrutura e função dos astrócitos. Os astrócitos interagem com outras células e com os sistemas circulatório, imune e neuroendócrino; são fundamentais para o metabolismo, sinaptogênese, neurogênese, neuroplasticidade e neuroproteção.
