星形胶质细胞是哺乳动物大脑中最丰富的胶质细胞,通过与神经元突触的动态且通常是双向的相互作用,是大脑发育和生理的关键调节剂。尽管星形胶质细胞对于建立和维持适当的突触连接具有明显的重要性,但我们对它们在脑功能中的作用的理解仍处于起步阶段。我们认为,这至少部分是由于我们对星形胶质细胞的细胞生物学及其与突触相互作用的机制的认识存在很大差距。在这篇综述中,我们总结了一些开创性的发现,产生重要的洞察星形胶质细胞神经元通信的细胞和分子基础,重点是星形胶质细胞在突触的发育和重塑的作用。此外,我们将提出一些迫切需要解决的问题,以促进我们的星形胶质细胞在调节突触发育的作用机制的理解。
Astrocytes, the most abundant glial cells in the mammalian brain, are critical regulators of brain development and physiology through dynamic and often bidirectional interactions with neuronal synapses. Despite the clear importance of astrocytes for the establishment and maintenance of proper synaptic connectivity, our understanding of their role in brain function is still in its infancy. We propose that this is at least in part due to large gaps in our knowledge of the cell biology of astrocytes and the mechanisms they use to interact with synapses. In this review, we summarize some of the seminal findings that yield important insight into the cellular and molecular basis of astrocyte-neuron communication, focusing on the role of astrocytes in the development and remodeling of synapses. Furthermore, we will pose some pressing questions that need to be addressed to advance our mechanistic understanding of the role of astrocytes in regulating synaptic development.
