    A Tissue Injury Sensing and Repair Pathway Distinct from Host Pathogen Defense

    The authors showed that, in contrast to most pathogen-induced cytokines, interleukin-24 was predominately induced by barrier epithelial progenitors after tissue injury and was independent of microbiome or adaptive immunity.

    Reprogramming by Drug-Like Molecules Leads to Regeneration of Cochlear Hair Cell–Like Cells in Adult Mice

    By single-cell RNAseq, investigators showed that MYC/NICD “rejuvenated” the adult mouse cochlea by activating multiple pathways including Wnt and cyclase activator of cyclic AMP, whose blockade suppressed cochlear hair cell-like cell regeneration despite Myc/Notch activation.

    Cell Cycle Controls Long-Range Calcium Signaling in the Regenerating Epidermis

    Researchers demonstrated that G2 cells were required to initiate normal levels of Ca2+ signaling, while connexin43 connected basal cells to orchestrate tissue-wide coordination of Ca2+ signaling.

    Defective NCOA4-Dependent Ferroptosis in Senescent Fibroblasts Retards Diabetic Wound Healing

    The expression of nuclear receptor coactivator 4 (NCOA4), a key factor that influenced ferritinophagy, was decreased in both diabetic wound tissue and high glucose-induced senescent fibroblasts.

    Release Systems Based on Self-Assembling RADA16-I Hydrogels with a Signal Sequence Which Improves Wound Healing Processes

    XTT and LDH tests on fibroblasts and keratinocytes were performed to assess the cytotoxicity of the RADA16-I hybrids, while the viability of cells treated with RADA16-I hybrids was evaluated in a model of human dermal fibroblasts.

    Dedifferentiation Maintains Melanocyte Stem Cells in a Dynamic Niche

    Scientists showed that most melanocyte stem cells toggled between transit-amplifying and stem cell states for both self-renewal and generation of mature progeny, a mechanism fundamentally distinct from those of other self-renewing systems.

    Methotrexate Suppresses Psoriatic Skin Inflammation by Inhibiting Muropeptide Transporter SLC46A2 Activity

    Investigators focused on Slc46a2, which was highly expressed in mammalian epidermal keratinocytes, and showed that it was critical for the delivery of diaminopimelic acid-muropeptides and activation of NOD1 in keratinocytes.

    Macrophages Mediate Psoriasis via Mincle-Dependent Mechanism in Mice

    Mechanistically, macrophages mediated psoriasis via the Mincle-Syk-NF-κB pathway, as blocking macrophage Mincle inhibited Syk/NF-κB-driven skin lesions and epidermal injury in vivo and in vitro.

    Heat Promotes Melanogenesis by Increasing the Paracrine Effects in Keratinocytes via the TRPV3/Ca2+/Hh Signaling Pathway

    Researchers found that heat stress promoted melanogenesis in pigment cells by increasing the paracrine effects of keratinocytes, and high-throughput RNA sequencing showed that heat stress activated the Hedgehog (Hh) signaling pathway in keratinocytes.

    The Journey From Melanocytes to Melanoma

    Scientists describe a new understanding of melanocyte biology and the different melanocyte subpopulations and microenvironments they inhabit, and how this provides unique insights into melanoma initiation and progression.
