Product Introduction
Bioactivity


英文名: Collagenase Type I

描述: Collagenase Type I 是一种蛋白水解酶，能分解胶原蛋白中的肽键（胶原蛋白是结缔组织的主要结构蛋白）。Collagenase 已被探索作为一种潜在的治疗选择来分解突出的椎间盘物质，从而减少对附近神经的压迫。Collagenase 可能有助于过度疤痕组织的分解和重组，潜在地改善组织功能和外观。Collagenase 具有治疗椎间盘突出、瘢痕疙瘩、脂肪团、脂肪瘤以及佩罗尼氏病和手掌纤维瘤病等方面的潜力。

体外活性: The objective of this study was to determine whether a peptide of type II collagen which can induce collagenase activity can also induce chondrocyte terminal differentiation (hypertrophy) in articulate cartilage. Results show that the induction of collagenase activity by a cryptic peptide sequence of type II collagen is accompanied by chondrocyte hypertrophy and associated with cellular and matrix changes. This induction occurs in the mid and superficial zones of previously healthy articular cartilage. This response of the chondrocyte to a cryptic sequence of denatured type II collagen may play a role in naturally occurring hypertrophy in endochondral ossification and in the development of cartilage pathology in osteoarthritis.[1]

体内活性: Ten New Zealand white rabbits were used as the experimental group and control group. After epithelial debridement, a collagenase type II solution (200 μL of 5 mg/mL) was applied in the experimental group at room temperature (24 °C) for 30 min, and a 200 μL solution without collagenase was applied in the control group. No obvious inflammatory reaction was observed in all eyes after the procedure. The differences in elastic modulus between the experimental and control group were statistically significant at 10% and 15% deformities. Collagenase type II treatment results in mimic KC with increased corneal keratometry and corneal thinning and a lower elastic modulus. An animal model for corneal ectasia can be generated by treatment with collagenase type II.[2]
