不同类型胶原蛋⽩的组织分布受到限制,具有特定的⽣物学功能,对组织稳态⾄关重要,随着我们对组织纤维化、 组织再生、组织老化和肿瘤发⽣过程的了解越来越多,这些功能正受到越来越多的关注。 I 型胶原蛋⽩是⼈体结缔 组织主要蛋白,由2条相同的 α 1链和1条 α 2链组成,组装成原纤维,构成结缔组织,为其它组织提供形态⽀撑;协调⻣骼、 肌腱、⽪肤和其他组织的形状和功能;在止血、伤口愈合、⾎管生成和生物矿化中发挥作⽤。III型胶原蛋⽩由3条相同 的α链组成,主要形成⽹状纤维,是中空器官(如⼤⾎管,⼦宫和肠道)的结构成分之⼀,也存在于与 I 型胶原相关的许 多其他组织,如⽪肤、软⻣等组织中,III型胶原通常与 I 型和V型等胶原聚合,形成异型原纤维。
在胚胎发育、组织创伤修复等过程中, 在必须承受拉伸的组织器官,例如胎盘,阴道和⼦宫组织中, I 型和 III 型等胶原蛋⽩都需要共同表达。因为, I 型和 III 型等胶原蛋⽩需要⾼度的协同配合,才能维持正常⽣理功能 。 I 型与 III 型等胶原蛋⽩⽐例的变化,可能会改变胶原原纤维的形态,诱发不同组织胶原纤维变异,进⽽引发多种疾病 。
