Abstract

Chronic wounds associated with vascular disease, diabetes mellitus, or aging are leading causes of morbidity in western countries and represent an unresolved clinical problem. The development of innovative strategies to promote tissue repair is therefore an important task that requires a more thorough analysis of the underlying molecular pathophysiology. We propose that the understanding of the complex biological events that control tissue repair or its failure largely benefits from a broad analytical approach as provided by novel proteomic methodologies. Here we present the first comparative proteome analysis of wound exudates obtained from normal healing or nonhealing (venous leg ulcer) human skin wounds. A total of 149 proteins were identified with high confidence. A minority of proteins was exclusively present in exudate of the healing wound (23 proteins) or the nonhealing wound (26 proteins). Of particular interest was the differential distribution of specific proteins among the two different healing phenotypes. Whereas in the exudate obtained from the healing wound mediators characteristic for tissue formation were abundantly present, in the exudate obtained from the nonhealing wound numerous mediators characteristic for a persistent inflammatory and tissue destructive response were identified. Furthermore, the study also revealed interesting results regarding the identification of new proteins with yet unknown functions in skin repair. This analysis therefore represents an important basis for the search for potential biomarkers, which give rise to a better understanding and monitoring of disease progression in chronic wounds.

  • Matrix metalloproteinases such as collagenase and gelatinases A and B are elevated in chronic wound fluids compared to acute wound fluid.

    “It has been shown that matrix metalloproteinases (MMPs), such as collagenase and gelatinases A and B, are elevated in chronic wound fluids when compared to acute wound fluid (25, 38).”
  • Recent investigations of chronic wound tissue and fluid indicate a continual competition between inflammatory and anti-inflammatory signals leading to a misbalanced environment for proper wound healing.

    “Specifically, recent investigations of chronic wound tissue and fluid indicate a continual competition between inflammatory and anti-inflammatory signals leading to a misbalanced environment for proper wound healing to occur (25, 26).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
