The ocular lens assembles two separate intermediate filament systems sequentially with differentiation. Canonical 8-11 nm IFs composed of Vimentin are assembled in lens epithelial cells and younger fiber cells, while the fiber cell-specific beaded filaments are switched on as fiber cell elongation initiates. Some of the key features of both filament systems are reviewed.
晶状体随着分化过程依次组装两个独立的中间丝系统。由波形蛋白组成的典型的8 - 11纳米中间丝在晶状体上皮细胞和较年轻的纤维细胞中组装,而纤维细胞特异性的串珠状丝在纤维细胞开始伸长时开启。本文综述了这两种丝系统的一些关键特征。
