Summary: The study demonstrates the significant promise of trichocyte keratins in promoting wound healing, with distinct behaviors and advantages observed among different types. Transcriptomic analysis reveals the regulatory mechanisms of keratins in cell proliferation, migration, and blood vessel generation. These findings can contribute to the development and precision application of keratins.

Summary: Burn healing is a dynamic process consisting of the inflammatory phase and the proliferative-remodeling phase. Autophagy plays a crucial role in skin homeostasis and wound healing, with both positive and negative effects. It has the ability to determine cell survival or death.

Summary: Wound healing is a complex process involving tissue protection, replacement, and reorganization, with the extracellular matrix and cellular events playing key roles. Matrix-regulated cellular macro-autophagy is crucial for tissue replacement and resolution in healing, while disruptions in matrix turnover can lead to chronic wounds or scarring. Although research on autophagy during wound healing is limited, the emerging picture suggests the central role of matrix-autophagy modulation in both physiological and pathological healing.

Summary: This study investigated the coordination function of electric fields (EFs) on wound healing and found that EF promotes wound contraction and re-epithelialization, accelerating the healing process. In vitro experiments demonstrated that EFs promote cell migration and collagen secretion. These findings support the continued development of EF for wound treatment applications.

Summary: PLY is a pore-forming toxin produced by Streptococcus pneumoniae, playing a dual role as a key bacterial virulence factor and a trigger for host immune modulation. It promotes bacterial colonization and survival, while also triggering innate and adaptive host immune responses against bacterial infection. PLY displays Yin and Yang properties during infection, promoting disease by membrane perforation and activating inflammatory pathways, while also mitigating damage by triggering host cell repair and initiating anti-inflammatory responses.

Summary: The application of amniotic membrane on chronic wounds has shown effectiveness in resetting wound healing, particularly in re-epithelialization. Amniotic membrane affects wound healing by modulating cell signaling pathways and growth factors. Additionally, it influences protein expression in epithelial cells, promoting the progression of re-epithelialization.

Summary: Topographical properties of biomaterials have important effects on cell activities and immune response during wound healing. The study found that an electrospinning membrane with a fiber diameter of 319 nm (A300) showed enhanced cell proliferation, wound healing, and keratinocyte migration, making it a potential candidate for skin regeneration applications.

Summary: Sea cucumber derived tetrapeptides VTPY and VLLY have the potential to promote wound healing by promoting reepithelialization, collagen and lipid regeneration, and enhancing angiogenesis. VTPY works better than VLLY, indicating their potential as natural food source-derived candidates for promoting skin wound healing.

Summary: Fundamental knowledge about cell-surface interactions can be used in the development of wound dressings and scaffolds that promote wound healing. Plasma-coating wound dressings with acid-functionalised monomers or amine functionalisation can enhance cell adhesion, proliferation, and migration. In an in vivo study on mice, dressings coated with allylamine showed increased wound healing rate and reduced wound area, while prolonged treatment with allylamine-functionalised dressings may impair healing. Acrylic acid functionalisation did not improve early wound healing, but promoted collagen deposition at a later stage. This suggests that plasma polymerisation can lead to the development of new dressings that enhance wound closure by directing cell behavior, but a timed approach may be necessary for their application.

Summary: The study demonstrates that bacterial cellulose (BC) scaffold has a significant promoting effect on epithelial regeneration and wound healing, improving the wound microenvironment and aiding in the maintenance and restoration of injured epidermis. Compared to collagen material, BC scaffold can enhance beneficial tissue repair by regulating the functional balance of macrophages.

Summary: Chronic wounds are often caused by bacterial contamination, with Staphylococcus aureus being a common strain. Inhibition of keratinocyte migration by S. aureus exudate may involve the upregulation of connexin-43 (Cx43). The treatment of bacterium-infected wounds may be improved by targeting Cx43 and Akt to overcome wound closure impairment.
