Wound recovery is a complex process that consists of multiple phases, each of which are indispensable for adequate repair. critical to their function.35 Recent studies show that circulating neutrophils from diabetic humans are primed to produce NETs and NETosis delayed diabetic wound healing in mice and humans.117,118 The involvement of NETs Protosappanin B was corroborated by showing that DNase I treatment enhanced wound healing in wild type diabetic mice.117 Altogether, these data support that limiting the activity of neutrophils may be beneficial for the treatment of recalcitrant wounds. Future studies are needed to establish the benefit from an array of compounds designed to specifically inhibit peptidylarginine deiminase 4 (PAD4), an essential enzyme in the formation of NETs. Interestingly, the Protosappanin B first generation PAD inhibitor, Cl-amidine, does not effectively block NETosis in human neutrophils, 119 but new specific PAD4 inhibitors have been developed to inhibit both NET formation and histone citrullination.120 Concluding remarks In summary, the healing of an adult skin wound is a complex process requiring the collaborative efforts of different tissues, cell lineages and soluble pro- and anti-inflammatory mediators. Components of the hemostatic and fibrinolytic systems play an indispensable role in the wound healing process. Besides their immediate contribution to the formation of a barrier clot against blood loss and pathogens, their cross talk with inflammatory cells lays the ground for antimicrobial activity, ECM degradation, keratinocyte migration and proliferation and wound contraction. Our understanding of wound healing mechanisms has progressed lately considerably. Area of the problems in unraveling cells restoration systems is a rsulting consequence cross-talk and redundancy in the machine. Many wound indicators most likely control several cell activity, and most cell activities are responses to cocktails of signals. Experimental mouse models have been particularly useful in answering open questions, because of our ability to manipulate the genetic, systemic, and wound environment. Although only a handful of knockout mice have been wounded so far, there have been some surprisingly normal healing phenotypes reported. Reports have raised questions around the validity of the essential prerequisite of inflammation for efficient tissue repair. Indeed, in experimental models of repair, inflammation has been shown to delay healing and to result in increased scarring. In this framework, the next few years in wound healing research will be exciting as we improve on our current understanding of the mechanisms controlling wound repair and test novel therapeutic targets to improve pathological would healing. ? Highlights Platelets, coagulation and fibrinolytic factors influence cutaneous wound healing. There is extensive crosstalk between the hemostatic system and the wound milieu. Timely resolution of each phase of wound healing is critical for wound repair. Buildup of active neutrophils, contributes to the development of chronic wounds.
