Eda通路(Eda, Edar, Edaradd)在牙齿发育过程中起到至关重要的作用,它决定着牙齿的数量、牙冠的形态和釉质的形成。在本项研究中,作者还发现Eda通路对牙根的形成也起到重要作用。

Eda通路(Eda, Edar, Edaradd)在牙齿发育过程中起到至关重要的作用,它决定着牙齿的数量、牙冠的形态和釉质的形成。在本项研究中,作者还发现Eda通路对牙根的形成也起到重要作用。

研究显示,Edar(Eda受体)表达于牙根发育过程中的Hertwig's上皮根鞘(HERS)。在基因突变小鼠中,长冠牙的发生几率明显增高,表现为:髓室增大,缺少或延迟的根分叉或根分三叉。Eda通路突变小鼠上颌第二磨牙长冠牙的发生几率最高,并且这种敏感性的增加恰巧与人EDA-A1突变患者相契合。这些大髓腔牙齿的形成是由于HERS在牙冠延伸的方位缺陷造成的,并伴随着毗邻的牙根间充质在扩大的延伸区域增殖。在这些牙齿中,HERS沿着牙冠伸展的角度变宽,进而变得更加垂直,以至于突变体HERSs无法沿着牙齿的中心到达正常的根分叉区,导致大髓腔牙齿的形成。然而,这种表型是多变的,也可表现为:伸展角度微弱的变化;增殖引起根分叉形成的延迟或者无影响。

结论:本研究是第一次对Eda通路在牙根发育中所扮演的角色进行探讨分析。研究显示,Eda通路对出生后小鼠的发育起到直接作用,表明:在一系列的综合症中,HERS增殖和延伸角度的变化可能是导致长冠牙发生的原因。
