Article Abstract
Chronic wounds can develop as a result of prolonged inflammation during the healing process, which can happen due to bacterial infection. Therefore, preventing infection and controlling inflammation can accelerate wound healing. Antimicrobial peptides have different protective properties in addition to antimicrobial activity. Some of these activities include the stimulation of cytokine or chemokine synthesis, the facilitation of chemotaxis and cell proliferation, the acceleration of cell proliferation, the induction of anti-inflammatory responses, and the promotion of wound repair. This study aimed to assess the wound healing potential of a novel in silico-designed antimicrobial peptide. Then, its anti-inflammatory activity was investigated by measuring the level of tumor necrosis factor-α (TNF-α) and transforming growth factor beta (TGF-β) as indicators of the wound healing process. In addition, the influence of the peptide on cell migration was evaluated by a scratch test on human dermal fibroblasts (HDF) and HaCaT cells as a human epidermal keratinocyte cell line. The results showed that our new peptide could act well in inhibiting TNF-α over-secretion while increasing the expression of TGF-β as an anti-inflammatory factor. This peptide showed a significant potential to stimulate HDF and HaCaT cell migration and proliferation. Therefore, using this peptide as an anti-inflammatory component of wound dressings may be promising.

Background: Intestinal cells receive incoming signals from neighboring cells and microbial communities. Upstream signaling pathways transduce these signals to reach transcription factors (TFs) that regulate gene expression. In inflammatory bowel disease (IBD), most single nucleotide polymorphisms (SNPs) are in non-coding genomic regions containing TF binding sites.

Normal cutaneous wound healing is a multicellular process that involves the release of small extracellular vesicles (sEVs) that coordinate intercellular communication by delivery of sEV payloads to recipient cells. We have recently shown how the pro-reparative activity of inflammatory cell sEVs, especially macrophage and neutrophil-derived sEVs, in the wound bed is dysregulated in impaired wound healing. Here we show that loss of Rab27A, a small GTPase that has a regulatory function in sEV secretion, reduces the release of neutrophil and macrophage-derived sEVs.

Wound healing is often hindered by bacterial infection, oxidative stress, and bleeding. Traditional dressings cannot simultaneously regulate multiple microenvironments. To address the shortcomings of traditional dressings, this study constructed a dual-network photothermal responsive multifunctional hydrogel OBCTCu based on four natural ingredients, including Bletilla striata polysaccharide (BSP), chitosan (CS), tannic acid (TA), and Cu.

Conventional wound dressings primarily focus on biochemical regulation, often neglecting the potential benefits of mechanical cues in tissue regeneration. We report a Janus hydrogel (QPJ hydrogel) that synergistically integrates biochemical modulation with temperature-responsive mechanical contraction for advanced chronic wound management. The hydrogel is constructed from quaternary ammonium chitosan (QCS) and N-isopropylacrylamide (NIPAM), with an outer PNIPAM layer that generates a directional contractile stress >25 kPa at physiological temperature.

Objective: Polychlorinated dibenzo-p-dioxins (PCDDs) present a significant long-term threat to human health attributable to their toxicological properties, chemical stability and propensity for bioaccumulation. This study seeks to explore the correlation between PCDDs exposure and prostate cancer (PCa) through comprehensive analysis.
Methods: The multi-dimensional analysis was conducted based on various online databases.
