    Decoding Molecular Programs in Melanoma Brain Metastases

    Molecularly, the expression of E-cadherin or nerve growth factor receptor, the BRAF mutation state, and level of immune cell infiltration subdivided tumors into proliferative/pigmented and invasive/stem-like/therapy-resistant.

    Reactive Metal Boride Nanoparticles Trap Lipopolysaccharide and Peptidoglycan for Bacteria-Infected Wound Healing

    Generation of an alkaline microenvironment enhanced boron dihydroxy groups ability to trap lipopolysaccharides or peptidoglycans through esterification, which enhanced metal cation-induced bacterial death and inhibited dead bacteria-induced excessive inflammation both in vitro and in vivo.

    Zwitterionic Polysaccharide-Based Hydrogel Dressing as a Stem Cell Carrier to Accelerate Burn Wound Healing

    In burnt murine animal models, the adipose-derived stem cells-laden hydrogel significantly accelerated wound healing rate and scarless skin tissue regeneration through multiple pathways, and could avoid immune system recognition and activation and thus reduced the inflammatory response.

    Abstract

    Therapeutic Silencing of p120 in Fascia Fibroblasts Ameliorate Tissue Repair

    Gene silencing of p120 in fascia fibroblasts disentangled their supracellular organization, reducing the transfer of fascial cells and extracellular matrix into wounds.
    [Journal of Investigative Dermatology]

    Abstract

    Nanoliposomal Peptides Derived From Spirulina platensis Protein Accelerate Full-Thickness Wound Healing

    Spirulina platensis is a type of blue-green algae that contains large amounts of protein with therapeutic effects. In-vitro MTT toxicity studies on the HFFF-2 cell line showed that the hydrolyzed peptides had no toxic effect and increased cell growth.

    AbstractGraphical Abstract

    The Human Pathobiont Malassezia furfur Secreted Protease Mfsap1 Regulates Cell Dispersal and Exacerbates Skin Inflammation

    Investigators observed that the loss of MFSAP1 resulted in dramatic changes in the cell adhesion and dispersal in both culture and a human 3D reconstituted epidermis model.

    Interferon-Gamma Signaling Promotes Melanoma Progression and Metastasis

    Treatment of mouse melanoma cell lines with interferon-gamma enhanced their tumorigenicity and metastasis in lung colonization allograft assays performed in immunocompetent syngeneic host mice, but not in immunocompromised host mice.

    Abstract

    Mesenchymal Stem/Stromal Cells Primed by Inflammatory Cytokines Alleviate Psoriasis-Like Inflammation via the TSG-6-Neutrophil Axis

    Researchers found that subcutaneous application of umbilical cord-derived mesenchymal stem/stromal cells primed by interferon-γ and tumor necrosis factor-α exhibited remarkable therapeutic efficacy on imiquimod-induced psoriasis-like inflammation in mice.
