Recent updates on mechanisms of cell-cell interaction in oligodendrocyte regeneration after white matter injury

Abstract

In most cases, neurological disorders that involve injuries of the cerebral white matter are accompanied by demyelination and oligodendrocyte damage. Promotion of remyelination process through the maturation of oligodendrocyte precursor cells (OPCs) is therefore proposed to contribute to the development of novel therapeutic approaches that could protect and restore the white matter from central nervous system diseases. However, efficient remyelination in the white matter could not be accomplished if various neighboring cell types are not involved to react with oligodendrocyte lineage cells in this process. Hence, profound understanding of cell-cell interaction between oligodendrocyte lineage cells and other cellular components is an essential step to achieve a breakthrough for the cure of white matter injury. In this mini-review, we provide recent updates on non-cell autonomous mechanisms of oligodendrocyte regeneration by introducing recent studies (e.g. published either in 2018 or 2019) that focus on crosstalk between oligodendrocyte lineage cells and the other constituents of the white matter.
