摘要: Astrocytes have been shown to protect neurons from delayed neuronal death and increase their survival in cerebral ischemia. One of the main mechanisms astrocyte protection is rapid removal excess glutamate synaptic sites by astrocytic plasma membrane transporters such as GLT-1/EAAT-2, reducing excitotoxicity. Astrocytic mitochondrial function essential for normal GLT-1 function. Manipulating thus an important strategy enhance improve outcome following Increasing evidence supports involvement microRNAs (miRNA), some them being astrocyte-enriched, regulation This chapter will first update information about astrocytes, GLT-1, mitochondria, death. Then we focus on two recently reported astrocyte-enriched miRNAs (miR-181 miR-29 families), effects mitochondria well after
