神经连接蛋白(NLS)是突触后跨膜细胞黏附蛋白,在兴奋性突触和抑制性突触的调节中起着关键作用。以往的体外和体内研究表明,NLS对突触的形成和突触传递有贡献。与它们的定位一致,NL1和NL3选择性地影响兴奋性突触,而NL2特异性地影响抑制性突触。在患有自闭症谱系障碍或精神发育迟缓的患者中发现了NL基因的缺失或突变,携带已报道的NL基因缺失或突变的小鼠表现出自闭症相关行为和突触功能障碍。相反,突触活性可以调节NLS的磷酸化、表达和切割,进而影响突触活性。因此,在临床研究中,确定NLS与突触功能的关系至关重要。在这篇综述中,我们主要讨论NLS和突触活动是如何相互影响的。
Neuroligins (NLs) are postsynaptic transmembrane cell-adhesion proteins that play a key role in the regulation of excitatory and inhibitory synapses. Previous in vitro and in vivo studies have suggested that NLs contribute to synapse formation and synaptic transmission. Consistent with their localization, NL1 and NL3 selectively affect excitatory synapses, whereas NL2 specifically affects inhibitory synapses. Deletions or mutations in NL genes have been found in patients with autism spectrum disorders or mental retardations, and mice harboring the reported NL deletions or mutations exhibit autism-related behaviors and synapse dysfunction. Conversely, synaptic activity can regulate the phosphorylation, expression, and cleavage of NLs, which, in turn, can influence synaptic activity. Thus, in clinical research, identifying the relationship between NLs and synapse function is critical. In this review, we primarily discuss how NLs and synaptic activity influence each other.
