Skin wounds can be caused by traumatic lacerations or incisions which disrupt the structural and functional integrity of the skin. Wound closure and primary intention treatment of the wound as soon as possible is crucial to avoid or minimize the risk of infection that can result in a compromised healing rate or advanced functional intricacy. The gold standard treatment for skin wound healing is suturing. Light-activated tissue sealing is an appealing alternative to sutures as it seals the wound edges minimizing the risk of infection and scarring, especially when utilized along with biodegradable polymeric biomaterials in the wound bed. Silk fibroins can be used as a biodegradable biomaterial that possesses properties supporting cell migration and proliferation in the tissue it interacts with. In addition, histamine treatment is shown to have extensive effects on cellular functions promoting wound healing. Here, the evaluation of Laser-activated Sealants (LASE) consisting of silk fibroin films induced with Indocyanine Green dye in a wound sealed with laser in the presence of Histamine receptor agonists H1R, H2R and H4R take place. The results were evaluated using Trans-epidermal Water Loss (TEWL), histological and analytical techniques where immune cell biomarkers Arginase-1, Ly6G, iNOS, Alpha-SMA, Proliferating Cell Nuclear Antigen (PCNA), and E-Cadherin were used to study the activity of specific cells such as macrophages, neutrophils, and myofibroblasts that aid in wound healing. PBS was used as a control for histamine receptor agonists. It was found that TEWL increased when treated with H1 receptor agonists while decreasing significantly in H2R and H4R-treated wounds. Arginase-1 activity improved, while it displayed an inverse relationship compared to iNOS. H4R agonist escalated Alpha-SMA cells, while others did not have any significant difference. Ly6G activity depleted in all histamine agonists significantly, while PCNA and E-Cadherin failed to show a positive or negative effect.
