Human skin provides both physical integrity and immunological protection from the external environment using functionally distinct layers, cell types and extracellular matrix. Despite its central role in human health and disease, the constituent proteins of skin have not been systematically characterized. Here, we combine advanced tissue dissection methods, flow cytometry and state-of-the-art proteomics to describe a spatially-resolved quantitative pro-teomic atlas of human skin. We quantify 10,701 proteins as a function of their spatial location and cellular origin. The resulting protein atlas and our initial data analyses demonstrate the value of proteomics for understanding cell-type diversity within the skin. We describe the quantitative distribution of structural proteins, known and previously undescribed proteins specific to cellular subsets and those with specialized immunological functions such as cytokines and chemokines. We anticipate that this proteomic atlas of human skin will become an essential community resource for basic and translational research (https://skin.science/).

ABSTRACT
Skin aging is a specific manifestation of the physiological aging process that occurs in virtually all organisms In this study, we used data independent acquisition mass spectrometry to perform a comparative analysis of protein expression in volar forearm skin samples from of 20 healthy young and elderly Chinese individuals. Our quantitative proteomic analysis identified a total of 95 differentially expressed proteins (DEPs) in aged skin compared to young skin. Enrichment analyses of these DEPs (57 upregulated and 38 downregulated proteins) based on the GO, KEGG, and KOG databases revealed functional clusters associated with immunity and inflammation, oxidative stress, biosynthesis and metabolism, proteases, cell proliferation, cell differentiation, and apoptosis. We also found that GAPDH, which was downregulated in aged skin samples, was the top hub gene in a protein-protein interaction network analysis. Some of the DEPs identified herein had been previously correlated with aging of the skin and other organs, while others may represent novel age-related entities. Our non-invasive proteomics analysis of human epidermal proteins may guide future research on skin aging to help develop treatments for age-related skin conditions and rejuvenation.
创伤是指由于各种致伤因素导致的机体软组织、骨骼甚至内脏器官等等各个系统的损伤,创伤可以根据发生地点、受伤部位、受伤组织、致伤因素及皮肤完整程度进行分类。 按发生地点分为战争伤、工业伤、农业伤、交通伤、体育伤、生活伤等;按受伤部位分为颅脑创伤、胸部创伤、腹部创伤、各部位的骨折和关节脱位、手部伤等;按受伤类型分为骨折、脱位、脑震荡、器官破裂等;相邻部位同时受伤者称为联合伤(如胸腹联合伤);按受伤的组织或器官分类时,又可按受伤组织的深浅分为软组织创伤、骨关节创伤和内脏创伤。软组织创伤指皮肤、皮下组织和肌肉的损伤,也包括行于其中的血管和神经。单纯的软组织创伤一般较轻,但广泛的挤压伤可致挤压综合征。血管破裂大出血亦可致命。骨关节创伤包括骨折和脱位,并按受伤的骨或关节进一步分类并命名。如股骨骨折、肩关节脱位等。内脏创伤又可按受伤的具体内脏进行分类和命名。如脑挫裂伤、肺挫伤、肝破裂等。同一致伤原因引起两个以上部位或器官的创伤,称为多处伤或多发伤。按致伤因素,分为火器伤、切伤、刺伤、撕裂伤、挤压伤、扭伤、挫伤等。按皮肤完整程度,分为闭合性创伤、开放性创伤等。
