ABCA1 and ischemia: Reactive astrocytes induced by ischemia are recently reported to participate in phagocytosis to clear neuronal debris, which is mediated by ATP-binding cassette transporter A1 (ABCA1) and the molecules in its pathway, such as multiple EGF-like-domains 10 (MEGF10) and the engulfment adapter phosphotyrosine binding domain containing 1 (GULP1) [211].
