Mirror Images of Contact Inhibitionversus Reactive Responsiveness Between
Axon and Myelin Sheath In Peripheral and Central Nervous System
Mirror image systems of influence between reactive responsiveness and contact inhibition pathways might help better delineate relationships between axon and its enwrapping myelin sheath. Indeed, a single integral system of axon with its myelin might implicate close analogous forms of influence between the Schwann cell or the oligodendrocyte and its related axon in a manner specifically involving gene expression as patterns of pathobiology in either peripheral or central demyelinative disorders. Indeed, in terms of a conceptual system that would go beyond simple myelin subcomponent constituent deficiency arising from gene deletion or gene mutation, one might perhaps conceive axonal participation in terms of anomalous gene expression as referable specifically in terms of interactive pathobiologic effects of disturbed contact inhibition and disturbed reactive responsiveness of Schwann cell or oligodendrocyte with its related axon.It is perhaps in terms particularly of a structured superimposition of multiple myelin subcomponents both in peripheral nerves and also in central white matter that one might better conceptualize a strict mirror image series of pathways of analogous influence in determining particularly pathobiologic patterns of evolving peripheral neuropathy and of central white matter injury. In simple terms, a single mechanism of axonal participation that predetermines oligodendrocyte or Schwann cell reactivity or contact inhibitory influence would essentially help account for demyelination as primarily an integral expression of genetic influence implicating also axons.

  接触抑制 contact inhibition
  是指在培养基质上,运动的多细胞动物的组织细胞,在互相接触后,双方的运动都停止下来,而不会发生一方超越另一方并继续前进的现象。是由M.Abercrombie与J.E.M.Heaysman(1953)从观察培养细胞中发现的。通过接触对运动的抑制是可逆的,经过一定时间以后,运动又会重新开始。肿瘤细胞之间,或者肿瘤细胞与正常细胞之间,并不发生接触抑制。一般认为接触抑制是细胞间的一种识别作用,对多细胞动物的形态形成与稳定具有重要性的作用。关于接触抑制的机制,有的认为是一种麻痹作用,有的认为是由细胞间的接着度与细胞、培养基质间的接着度之差而决定的。关于细胞的增殖,也有接触抑制的问题,进行单层培养的细胞,在培养器的底部形成一层后,在它的上面就会看到增殖停止,而不会形成多层。通常已肿疡化细胞,因接触使增殖受到抑制的性质比较弱,进行培养时就不会停留在单层。(王佑林
