一般描述

D-(+)-海藻糖是由两分子 α-葡萄糖组成的二糖。它在多种细胞冷冻培养基中作为冷冻保护剂。用作运输介质中的保护剂。它主要存在于支持低湿休眠（无水生活）的物种中。它可作为微生物中的碳水化合物储备，并保护它们免受不利条件的影响，如热、冷、脱水、干燥和氧化。海藻糖可以作为影响蛋白质折叠的化学伴侣。已知它可防止产生淀粉样蛋白和 β-淀粉样蛋白堆积。在亨廷顿蛋白聚集中也观察到了海藻糖的类似作用。因此，它可以作为阿尔茨海默氏′病和亨廷顿′病的保护剂。海藻糖能更好的刺激 沙门氏菌 细胞的初期生长。

应用

D-(+)-海藻糖可被用作某些细胞培养的碳水化合物储备，用以抵御环境压力。 它还可用于作为单克隆抗体生物制药配方的蛋白稳定剂。

Silicosis is an occupational lung disease characterized by persistent inflammation and irreversible fibrosis. Crystalline silica (CS) particles are mainly phagocytized by alveolar macrophages (AMs), which trigger apoptosis, inflammation, and pulmonary fibrosis. Previously, we found that autophagy-lysosomal system dysfunction in AMs
