玻璃体中的硫酸软骨素
2022-04-23 18:24:00 【微电子学与固体电子学-俞驰】
根据【1】描述的玻璃体混浊的原理:
硫酸软骨素(CS)是属于糖胺聚糖(glycosaminoglycans, GAGs)类的多糖
| 硫酸软骨素结构 | 占比(总硫酸软骨素) |
| 4S | 48.8% |
| 0S | 37.6% |
| 6S | 11.9% |
| 2S6S | 1.5% |
| 2S4S | 0.3% |

-----------------------------------------------------------------------------------------------------------------------------------------
玻璃体含有两种硫酸软骨素蛋白聚糖,即IX型胶原和versican【2】
我们的结果显示,硫酸软骨素的丢失与IX型胶原核心蛋白免疫金标记的丢失之间存在强烈的相关性,两者的半衰期均为11年
MMP23已在人类玻璃体体液23中被证实,这种酶能够破碎IX型胶原并导致玻璃体液化

另外根据【3】
硫酸软骨素用来软骨增长
氨糖软骨素(氨基葡萄糖)用来抑制磨损
