Astrocytes are a type of glial cell in the brain that play a crucial role in maintaining the health and function of neurons. Research in astrocyte function aims to better understand the various roles these cells play in the brain, including regulating the chemical environment, supporting neuronal communication, and influencing synaptic activity. Additionally, studies are investigating how astrocyte dysfunction may contribute to neurological disorders such as Alzheimer's disease, epilepsy, and depression. Overall, research in astrocyte function seeks to uncover the complex interactions between astrocytes and neurons to deepen our understanding of brain function and potential therapeutic targets for neurological diseases.
