10 香港中文大學年報 CUHK Annual Report 2018–2019 糖尿病人血管功能受損與細胞之 間物質傳導有關 黃聿教授（左一）領導的團隊發現細胞 之間的傳導機制與二型糖尿病有關。其 研究顯示「精氨酸酶1」影響一氧化氮的 合成，破壞血管內皮功能，引發心血管 疾病。 Cell-to-cell signal detected that can lead to poor blood-vessel function in diabetic patients A team led by Prof. Huang Yu (1st left) revealed a new cell-to-cell communication mechanism that contributes to Type II diabetes. The research shows that the enzyme arginase 1 inhibits the production of essential nitric oxide in the endothelial cells that form the lining of blood vessels, impairing the proper function of the vessels.
