Acetylcholine Receptor Clustering at Neuronal Synapses

IBN：95154560 PI：Margiotta 神经细胞或神经元主要通过化学突触进行功能性接触。 每个突触都是高度特化的，用于从突触前细胞末端释放神经递质分子，以及通过突触后细胞上的膜对特定神经递质分子进行分子接收。 受体结构由膜蛋白组成，这些受体通常聚集在突触前释放位点附近。 这些受体分子是如何聚集在突触后膜上的，目前还不清楚。 该项目利用分子和生物化学方法分离和鉴定一种潜在的重要蛋白质的基因序列、表达和功能作用，该蛋白质与一种常见神经递质乙酰胆碱的受体聚集有关。 研究结果对于神经科学来说是非常重要的，因为突触对于神经元的信号传递至关重要。 识别对受体聚集很重要的分子将是更好地理解突触如何形成及其功能的核心。

IBN: 95154560 PI: Margiotta Nerve cells, or neurons, communicate with each other primarily at functional contacts called chemical synapses. Each synapse is highly specialized for the release of neurotransmitter molecules from the presynaptic cell terminal, and for molecular reception of the particular neurotransmitter molecules by the membrane on the postsynaptic cell. The receptor structures are made of membrane proteins, and these receptors often are clustered right near the sites of presynaptic release. It remains unknown how those receptor molecules become clustered in the postsynaptic membranes. This project utilizes molecular and biochemical approaches to isolate and identify the genetic sequences, expression, and functional role of a potentially important protein that is associated with clustering of receptors for a common neurotransmitter, acetylcholine. Results will be important for neuroscience in general because synapses are crucial for neuronal signaling. Identification of the molecules important for receptor clustering will be central to achieving a better understanding of how synapses form and how they function.
