These wounds have a heterogeneous etiology, including diabetes and surgical trauma wounds. It is therefore important to decipher molecular signatures that reflect the macroscopic process of wound healing. To this end, we collected wound sponge dressings routinely used in vacuum assisted therapy after surgical trauma to generate wound-derived protein profiles via global mass spectrometry. We confidently identified 311 proteins in exudates. Among them were expected targets belonging to the immunoglobulin superfamily, complement, and skin-derived proteins, such as keratins. Next to several S100 proteins, chaperones, heat shock proteins, and immune modulators, the exudates presented a number of redox proteins as well as a discrete neutrophil proteomic signature, including for example cathepsin G, elastase, myeloperoxidase, CD66c, and lipocalin 2. We mapped over 200 post-translational modifications (PTMs; cysteine/methionine oxidation, tyrosine nitration, cysteine trioxidation) to the proteomic profile, for example, in peroxiredoxin 1. Investigating manually collected exudates, we confirmed presence of neutrophils and their products, such as microparticles and fragments containing myeloperoxidase and DNA. These data confirmed known and identified less known wound proteins and their PTMs, which may serve as resource for future studies on human wound healing KW - - KW - chaperones KW - damage-associated molecular patterns KW - heat-shock proteins KW - mass spectrometry KW - matrix metalloproteinase KW - peptidases KW - post-translational modifications KW - redox regulation UN - https://nbn-resolving.org/urn:nbn:de:gbv:9-opus-65267 SN - 1422-0067 SS - 1422-0067 U6 - https://doi.org/10.3390/ijms19030761 DO - https://doi.org/10.3390/ijms19030761 VL - 19 IS - 3 SP - 23 S1 - 23 PB - MDPI CY - Basel ER -
