Photopolymerized keratin-PGLa hydrogels for antibiotic resistance reversal and enhancement of infectious wound healing.

ABSTRACT: Infectious wounds have become serious challenges for both treatment and management in clinical practice, so development of new antibiotics has been considered an increasingly difficult task. Here, we report the design and synthesis of keratin 31 (K31)-peptide glycine-leucine-amide (PGLa) photopolymerized hydrogels to rescue the antibiotic activity of antibiotics for infectious wound healing promotion. K31-PGLa displayed an outstanding synergistic effect with commercial antibiotics against drug-resistant bacteria by down-regulating the synthesis genes of efflux pump. Furthermore, the photopolymerized K31-PGLa/PEGDA hydrogels effectively suppressed drug-resistant bacteria growth and enhanced skin wound closure in murine. This study provided a promising alternative strategy for infectious wound treatment.

Living microecological hydrogels for wound healing.

Project description:Chronic hard-to-heal wounds draw great attention worldwide, as their treatments are limited by infections and hypoxia. Inspired by the natural oxygen production capacity of algae and the competitive advantage of beneficial bacteria over other microbes, we presented a living microecological hydrogel (LMH) with functionalized Chlorella and Bacillus subtilis encapsulation to realize continuous oxygen delivery and anti-infections for promoting chronic wound healing. As the hydrogel consisted of thermosensitive Pluronic F-127 and wet-adhesive polydopamine, the LMH could keep liquid at a low temperature while quickly solidifying and tightly adhering to the wound bed. It was demonstrated that by optimizing the proportion of the encapsulated microorganism, the Chlorella could continuously produce oxygen to relieve hypoxia and support the proliferation of B. subtilis, while B. subtilis could eliminate the colonized pathogenic bacteria. Thus, the LMH substantially promoted the healing of infected diabetic wounds. These features make the LMH valuable for practical clinical applications.

Keratin isoform shifts modulate motility signals during wound healing.

Project description:Keratin intermediate filaments form strong mechanical scaffolds that confer structural stability to epithelial tissues, but the reason this function requires a protein family with fifty-four isoforms is not understood. During skin wound healing, a shift in keratin isoform expression alters the composition of keratin filaments. How this change modulates cellular function to support epidermal remodeling remains unclear. We report an unexpected effect of keratin isoform variation on kinase signal transduction. Increased expression of wound-associated keratin 6A, but not of steady-state keratin 5, potentiated keratinocyte migration and wound closure without compromising epidermal stability by activating myosin motors. This pathway depended on isoform-specific interaction between intrinsically disordered keratin head domains and non-filamentous vimentin shuttling myosin-activating kinases. These results substantially expand the functional repertoire of intermediate filaments from their canonical role as mechanical scaffolds to include roles as signaling scaffolds that spatiotemporally organize signal transduction cascades depending on isoform composition.

eIF6 modulates skin wound healing by upregulating keratin 6B.

Project description:Eukaryotic translation initiation factor 6 (eIF6) plays a crucial role in 60S ribosome biogenesis and protein translation, as well as in hypertrophic scar formation, but its potential role in epithelialization is still poorly understood. Herein, we found that eIF6 negatively correlated with the wound healing process. Mice with genetically knockdown eIF6 (eIF6+/-) showed faster re-epithelization as shown by the longer tongue of the newly formed epidermis. Furthermore, eIF6 ablation accelerated the wound healing process by targeting basal keratinocytes in the eIF6 keratinocyte-conditional knockout (eIF6f/+; Krt5-Cre+) mice. Mechanistically, keratin 6B, an important wound-activated protein, was significantly upregulated in eIF6f/+; Krt5-Cre+ mice skin as proved by RNA-seq, western immunoblots, and immunofluorescence staining. Moreover, an elevated level of KRT6B and accelerated proliferative capacity were also observed in stable knockdown eIF6 HaCaT cells. Taken together, eIF6 downregulation could accelerate epithelialization by upregulating KRT6B expression and promoting keratinocyte proliferation. Our results for the first time indicate that eIF6 might be a novel target to regulate re-epithelialization.

Polydopamine Antioxidant Hydrogels for Wound Healing Applications.

Project description:Antioxidants are known to improve the wound healing process and are researched as a therapeutic strategy to treat chronic wounds. Dopamine is a known neurotransmitter with antioxidant properties that can be polymerized to form polydopamine (PDA). Herein, polydopamine is demonstrated as an antioxidant biomaterial. In prior work, we developed methodology to prepare hydrogels by crosslinking polysaccharides with polyamines via epichlorohydrin and NaOH. Using this previously developed methodology, dextran hydrogels crosslinked with polydopamine were prepared. Darkening of the gels indicated the increasing incorporation of polydopamine within the hydrogels. In addition to basic pH, polydopamine can be formed by reaction with polyethylene imine (PEI), which results in PEI-PDA copolymer. Dextran was similarly crosslinked with the PEI-PDA copolymer and resulted in sturdier, darker gels, which had more polydopamine incorporated. Hydrogel morphology and strength were dependent on the feed ratios of dopamine. Antioxidant activity of polydopamine containing hydrogel was confirmed and shown to be dependent on the amount of dopamine used in hydrogel synthesis. Hydrogels with 0.5 dopamine to dextran feed ratio scavenged 78.8% of radicals in a 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) antioxidant assay while gels with no dopamine scavenged only 1.4% of radicals. An ex vivo wound healing assay showed considerable cell migration with the PEI-PDA containing hydrogel.

Angiogenic Hydrogels to Accelerate Early Wound Healing.

Project description:Diabetes mellitus affects an increasing proportion of the population, and is projected to double by 2060. Comorbidities contribute to an interrupted healing process which is delayed, prolonged, and associated with increased susceptibility to infection and unresolved inflammation. This leads to chronic nonhealing wounds and potential amputation. Here, the use of a bioactive angiogenic peptide-based hydrogel, SLan, is examined to improve early wound healing in diabetic rats, and its performance is compared to clinically utilized biosynthetic peptide-based materials such as Puramatrix. Streptozotocin-treated diabetic rats underwent 8 mm biopsy wounding in their dorsum. Wounds are treated with either Low (1 w%) SLan, High (4 w%) SLan, phosphate buffered saline (PBS), Puramatrix, or K2 (an unfunctionalized nonbioactive control sequentially similar to SLan), covered with Tegaderm, and monitored on for a month; animals are sacrificed for histomorphic analyses and immunostaining. Pharmacokinetic analysis showing no trafficking of peptides from the wound into the circulation. SLan groups show similar wound contraction as control groups (Puramatrix, PBS, and K2), however, showing marked improvement in healing in earlier time points, including increased deposition of new mature blood vessels. Altogether the results suggest this material can be used to "jumpstart" the diabetic wound healing process.

Self-Healing Supramolecular Hydrogels with Antibacterial Abilities for Wound Healing.

Project description:Wound healing due to skin defects is a growing clinical concern. Especially when infection occurs, it not only leads to impair healing of the wound but even leads to the occurrence of death. In this study, a self-healing supramolecular hydrogel with antibacterial abilities was developed for wound healing. The supramolecular hydrogels inherited excellent self-healing and mechanical properties are produced by the polymerization of N-acryloyl glycinamide monomers which carries a lot of amides. In addition, excellent antibacterial properties are obtained by integrating silver nanoparticles (Ag NPs) into the hydrogels. The resultant hydrogel has a demonstrated ability in superior mechanical properties, including stretchability and self-healing. Also, the good biocompatibility and antibacterial ability have been proven in hydrogels. Besides, the prepared hydrogels were employed as wound dressings to treat skin wounds of animals. It was found that the hydrogels could significantly promote wound repair, including relieving inflammation, promoting collagen deposition, and enhancing angiogenesis. Therefore, such self-healing supramolecular hydrogels with composite functional nanomaterials are expected to be used as new wound dressings in the field of healthcare.

Living Bacterial Hydrogels for Accelerated Infected Wound Healing.

Project description:Damaged skin cannot prevent harmful bacteria from invading tissues, causing infected wounds and even serious tissue damage. Traditional treatments can not only kill pathogenic bacteria, but also suppress the growth of beneficial bacteria, thus destroying the balance of the damaged skin microbial ecosystem. Here, a living bacterial hydrogel scaffold is reported that accelerates infected wound healing through beneficial bacteria secreting antibacterial substances. Lactobacillus reuteri, a common probiotic, is encapsulated in hydrogel microspheres by emulsion polymerization and further immobilized in a hydrogel network by covalent cross-linking of methacrylate-modified hyaluronic acid. Owing to light-initiated crosslinking, the hydrogel dressing can be generated in situ at the wound site. This hydrogel scaffold not only protects bacteria from immune system attack, but also prevents bacteria from escaping into the local environment, thus avoiding potential threats. Both in vitro and in vivo experiments show that it has excellent ability against harmful bacteria and anti-inflammatory capabilities, promoting infected wound closure and new tissue regeneration. This work may open up new avenues for the application of living bacteria in the clinical management of infected wounds.

Functional hydrogels promote chronic infectious wound healing by re-rousing macrophage M1 and inducing bacterial copper-like death.

Project description:Traditional antibiotics are often ineffective against biofilm-associated infections, and biofilm-induced macrophage immune evasion directly halts the wound healing process. Disrupting biofilms and regulating macrophage immune functions are critical to improving wound healing. In this study, we synthesized g-C3N4 with peroxidase (POD) enzyme activity via thermal polymerization and copper alginate microspheres (CAM) via gas cutting. These were co-encapsulated into GelMA hydrogels to form a functionalized wound repair system (GelMA/CAM@g-C3N4) with both anti-biofilm and local immune microenvironment remodeling capabilities. In vitro, this system exhibited excellent biocompatibility and promoted endothelial cell migration, vascular formation, and CD31 expression. It also polarized macrophages toward the M1 phenotype, restoring their pro-inflammatory functions, upregulating inflammatory cytokines (IL-1, IL-6, TNF-α), and inhibiting Staphylococcus aureus and Escherichia coli. In vivo, the system suppressed S. aureus growth, promoted angiogenesis and collagen deposition, and reshaped the pathological microenvironment to achieve wound repair and regeneration. Conclusions: This system offers a new therapeutic strategy for chronic infectious wounds.

Antibacterial smart hydrogels: New hope for infectious wound management.

Project description:Millions of people die annually due to uncured wound infections. Healthcare systems incur high costs to treat wound infections. Tt is predicted to become more challenging due to the rise of multidrug-resistant conditions. During the last decades, smart antibacterial hydrogels could attract attention as a promising solution, especially for skin wound infections. These antibacterial hydrogels are termed 'smart' due to their response to specific physical and chemical environmental stimuli. To deliver different drugs to particular sites in a controlled manner, various types of crosslinking strategies are used in the manufacturing process. Smart hydrogels are designed to provide antimicrobial agents to the infected sites or are built from polymers with inherent disinfectant properties. This paper aims to critically review recent pre-clinical and clinical advances in using smart hydrogels against skin wound infections and propose the next best thing for future trends. For this purpose, an introduction to skin wound healing and disease is presented and intelligent hydrogels responding to different stimuli are introduced. Finally, the most promising investigations are discussed in their related sections. These studies can pave the way for producing new biomaterials with clinical applications.

Fluorinated Methacrylamide Chitosan Hydrogels Enhance Cellular Wound Healing Processes.

Project description:Low availability of oxygen can lead to stalled wound healing processes and chronic wounds. To address local hypoxia and to better understand direct cellular benefits, a perfluorocarbon conjugated chitosan (MACF) hydrogel that delivers oxygen was created and applied for the first time to in vitro cultures of human dermal fibroblasts and human epidermal keratinocytes under both normoxic (21% O2) and hypoxic (1% O2) environments. Results revealed that local application of MACF provided 233.8 ± 9.9 mmHg oxygen partial pressure at 2 h and maintained equilibrium oxygen levels that were approximately 17 mmHg partial pressure greater than untreated controls. Cell culture experiments showed that MACF oxygenating gels improved cellular functions involved in wound healing such as cell metabolism, total DNA synthesis and cell migration under hypoxia in both fibroblasts and keratinocytes. Adenosine triphosphate (ATP) quantification also revealed that MACF treatments improved cellular ATP levels significantly over controls under both normoxia and hypoxia (p < 0.005). In total, these studies provide new data to indicate that supplying local oxygen via MACF hydrogels under hypoxic environments improves key wound healing cellular functions.
