In the central nervous system a disintegrin and metalloproteinase 10 (ADAM10) controls several functions such as neurodevelopment, synaptic plasticity and dendritic spine morphology thanks to its activity towards a high number of substrates, including the synaptic cell adhesion molecules as the Amyloid Precursor Protein, N-cadherin, Notch and Ephrins. In particular, ADAM10 plays a key role in the modulation of the molecular mechanisms responsible for dendritic spine formation, maturation and stabilization and in the regulation of the molecular organization of the glutamatergic synapse. Consequently, an alteration of ADAM10 activity is strictly correlated to the onset of different types of synaptopathies, ranging from neurodevelopmental disorders, i.e. autism spectrum disorders, to neurodegenerative diseases, i.e. Alzheimer's Disease. Areas covered: We describe the most recent discoveries in understanding of the role of ADAM10 activity at the glutamatergic excitatory synapse and its involvement in the onset of neurodevelopmental and neurodegenerative disorders. Expert opinion: A progress in the understanding of the molecular mechanisms driving ADAM10 activity at synapses and its alterations in brain disorders is the first step before designing a specific drug able to modulate ADAM10 activity.
在中枢神经系统中,解整合素金属蛋白酶10(ADAM10)可调控多种功能,如神经发育、突触可塑性和树突棘形态,这得益于其对大量底物的活性作用,这些底物包括作为淀粉样前体蛋白、N-钙黏蛋白、Notch和Ephrins的突触细胞黏附分子。特别是,ADAM10在调节负责树突棘形成、成熟和稳定的分子机制以及谷氨酸能突触的分子组织调控中发挥关键作用。因此,ADAM10活性的改变与不同类型突触病变的发生密切相关,这些病变范围从神经发育障碍(如自闭症谱系障碍)到神经退行性疾病(如阿尔茨海默病)。涵盖领域:我们描述了在理解ADAM10活性在谷氨酸能兴奋性突触中的作用及其在神经发育和神经退行性疾病发生中的参与方面的最新发现。专家观点:在设计能够调节ADAM10活性的特定药物之前,了解驱动ADAM10在突触处活性及其在脑部疾病中改变的分子机制是第一步。
