S100A8 and S100A9 belong to the damage-associated molecular pattern molecules. They are upregulated in a number of inflammatory skin disorders. Owing to their abundance in myeloid cells, the main function of S100A8/A9 has been attributed to their role in inflammatory cells. However, it is becoming increasingly clear that they also exert important roles in epithelial cells. In this review, we discuss the context-dependent function of S100A8/A9 in epithelial cells and their impact on wound healing, psoriasis and other skin diseases.
S100A8 和 S100A9 属于损伤相关分子模式分子。它们在许多炎症性皮肤病中上调。由于它们在髓样细胞中丰富,S100A8/A9 的主要功能归因于它们在炎症细胞中的作用。然而,越来越明显的是,它们在上皮细胞中也发挥着重要作用。在这篇综述中,我们讨论了 S100A8/A9 在上皮细胞中的上下文相关功能及其对伤口愈合、银屑病和其他皮肤病的影响。
