Project Summary An intact blood-retinal barrier (BRB) is critical for the maintenance of the health of the retina. The endothelial cells of the retinal blood vessels along with the surrounding pericytes and astrocytes form a neurovascular unit with strong barrier properties. Very little is known about the molecular and cellular mechanisms that regulate the development and maintenance of the BRB. We hypothesize that retinoic acid (RA) plays a critical role in the regulation of BRB formation as well as maintenance. We will test this hypothesis using a novel zebrafish model that we have developed, which allows the longitudinal in vivo visualization and testing of the BRB.

项目摘要 完整的血液屏障（BRB）对于维持视网膜健康至关重要。内皮 视网膜血管的细胞以及周围的周细胞和星形胶质细胞形成神经血管单元 具有强大的屏障特性。关于调节的分子和细胞机制知之甚少 BRB的开发和维护。我们假设视黄酸（RA）在 BRB形成和维护的调节。我们将使用新型斑马鱼检验这一假设 我们已经开发的模型，允许BRB的纵向在体内可视化和测试。
