Abstract

Dermal white adipose tissue (dWAT) is increasingly appreciated as a special fat depot. The adipocytes in this depot exert a variety of unique effects on their surrounding cells and can undergo massive phenotypic changes. Significant modulation of dWAT content can be observed both in intrinsically and extrinsically aged skin. Specifically, skin that has been chronically photo-damaged displays a reduction of the dWAT volume, caused by the replacement of adipocytes by fibrotic structures. This is likely to be caused by the recently uncovered process described as "adipocyte-myofibroblast transition" (AMT). In addition, contributions of dermal adipocytes to the skin aging processes are also indirectly supported by spatial correlations between the prevalence of hypertrophic scarring and the appearance of signs of skin aging in different ethnic groups. These observations could elevate dermal adipocytes to prime targets in strategies aimed at counteracting skin aging.

摘要

真皮白色脂肪组织(dWAT)日益被视为一种特殊的脂肪储存库。该储存库中的脂肪细胞对其周围细胞发挥着多种独特作用,并且能够经历大规模的表型变化。在自然老化和外在老化的皮肤中均可观察到dWAT含量的显著调节。具体而言,长期受到光损伤的皮肤会出现dWAT体积减小,这是由于脂肪细胞被纤维结构取代所致。这可能是由最近发现的被称为“脂肪细胞-肌成纤维细胞转变”(AMT)的过程引起的。此外,不同种族中肥厚性瘢痕的发生率与皮肤老化迹象的出现之间的空间相关性也间接支持了真皮脂肪细胞对皮肤老化过程的影响。这些观察结果可能会使真皮脂肪细胞成为旨在对抗皮肤老化的策略中的主要靶点。
