The major constituents of the myelin sheath are lipids, which are made up of fatty acids (FAs). The hydrophilic environment inside the cells requires FAs to be bound to proteins, preventing their aggregation. Fatty acid binding proteins (FABPs) are one class of proteins known to bind FAs in a cell. Given the crucial role of FAs for myelin sheath formation we investigated the role of FABP7, the major isoform expressed in oligodendrocyte progenitor cells (OPCs), in developmental myelination and remyelination. Here, we show that the knockdown of Fabp7 resulted in a reduction of OPC differentiation in vitro. Consistent with this result, a delay in developmental myelination was observed in Fabp7 knockout animals. This delay was transient with full myelination being established before adulthood. FABP7 was dispensable for remyelination, as the knockout of Fapb7 did not alter remyelination efficiency in a focal demyelination model. In summary, while FABP7 is important in OPC differentiation in vitro, its function is not crucial for myelination and remyelination in vivo.

脂肪酸结合蛋白 FABP7 是髓鞘形成过程中最佳少突胶质细胞分化所必需的,而髓鞘再生过程中则不需要。

髓鞘的主要成分是脂质,由脂肪酸 (FAs) 组成。细胞内的亲水环境需要 FA 与蛋白质结合,防止它们聚集。脂肪酸结合蛋白 (FABP) 是已知在细胞中结合 FA 的一类蛋白质。鉴于 FA 在髓鞘形成中的关键作用,我们研究了 FABP7(在少突胶质祖细胞 (OPCs) 中表达的主要同种型)在发育髓鞘形成和髓鞘再生中的作用。在这里,我们表明 Fabp7 的敲低导致体外 OPC 分化的减少。与该结果一致,在 Fabp7 敲除动物中观察到发育髓鞘形成延迟。这种延迟是短暂的,在成年之前就建立了完全的髓鞘形成。FABP7 对于髓鞘再生是可有可无的,因为 Fapb7 的敲除并没有改变局灶性脱髓鞘模型中的髓鞘再生效率。总之,虽然 FABP7 在体外 OPC 分化中很重要,但其功能对于体内髓鞘形成和髓鞘再生并不重要。
