Bonafide claudin proteins are functional and structural components of tight junctions and are largely responsible for barrier formation across epithelial and endothelial membranes. However, current advances in the understanding of claudin biology have revealed their unexpected functions in the brain. Apart from maintaining blood-brain barriers in the brain, other functions of claudins in neurons and at synapses have been largely elusive and are just coming to light. In this review, we summarize the functions of claudins in the brain and their association in neuronal diseases. Further, we go on to cover some recent studies that show that claudins play signaling functions in neurons by regulating trafficking of postsynaptic receptors and controlling dendritic morphogenesis in the model organism Caenorhabditis elegans.

大脑中的claudins:神经元中的非常规功能。

Bonafide claudin蛋白是紧密连接的功能和结构成分,在上皮和内皮膜的屏障形成中起主要作用。但是,对claudin生物学了解的最新进展表明它们在大脑中具有意想不到的功能。除了维持大脑中的血脑屏障外,神经元和突触中claudins的其他功能在很大程度上还难以捉摸,并且刚刚被发现。在这篇综述中,我们总结了claudins在大脑中的功能及其在神经元疾病中的关联。此外,我们继续涵盖一些最近的研究,这些研究表明claudins通过调节模型生物秀丽隐杆线虫中突触后受体的运输和控制树突形态发生而在神经元中发挥信号传导功能。
