    Evolution of Delayed Resistance to Immunotherapy in a Melanoma Responder

    Researchers studied 37 tumor samples over nine years from a patient with metastatic melanoma with complete clinical response to immune checkpoint blockade followed by delayed recurrence and death.

    Skin-Resident Immune Cells Actively Coordinate Their Distribution with Epidermal Cells during Homeostasis

    By tracking individual cells in the skin of live adult mice over time, researchers showed that Langerhans cells and dendritic epidermal T cells actively maintained a non-random spatial distribution despite continuous turnover of neighboring basal epithelial cells.

    Abstract

    Single-Keratinocyte Transcriptomic Analyses Identify Different Clonal Types and Proliferative Potential Mediated by FOXM1 in Human Epidermal Stem Cells

    Scientists reported that single-cell transcriptome analysis of primary human epidermal cultures identified categories of genes clearly distinguishing the different keratinocyte clonal types, which were hierarchically organized along a continuous, mainly linear trajectory showing that stem cells sequentially generated progenitors producing terminally differentiated cells.

    Mapping the Molecular and Structural Specialization of the Skin Basement Membrane for Inter-tissue Interactions

    The epithelial–fibroblast interface, namely, hair germ–dermal papilla interface, makes asymmetrically organized side-specific heterogeneity in the basement membrane (BM), defined by the newly characterized interface, hook and mesh BMs.

    Single Cell Transcriptional Zonation of Human Psoriasis Skin Identifies an Alternative Immunoregulatory Axis Conducted by Skin Resident Cells

    Investigators deconstructed the full-thickness human skins of both healthy donors and patients with psoriasis vulgaris at single cell transcriptional level, and further built a neural-network classifier to evaluate the evolutional conservation of skin cell types between mouse and human.

    Abstract

    Metformin Ameliorates Scleroderma via Inhibiting Th17 Cells and Reducing mTOR-STAT3 Signaling in Skin Fibroblasts

    Scientists measured mTOR-STAT3 signaling in skin fibroblasts and found that phosphorylated mTOR and phosphorylated STAT3 protein expression were decreased by metformin treatment.

    Loss of Ambra1 Promotes Melanoma Growth and Invasion

    Scientists provided evidence that the Activating Molecule in Beclin-1-Regulated Autophagy (Ambra1) contributed to melanoma development.

    Targeting Non-Canonical Activation of GLI1 by the SOX2-BRD4 Transcriptional Complex Improves the Efficacy of HEDGEHOG Pathway Inhibition in Melanoma

    Researchers identified a novel SOX2-BRD4 transcriptional complex driving the expression of GLI1, the final effector of the Hedgehog/GLI (HH/GLI) pathway, providing a novel mechanism of non-canonical Smoothened-independent activation of HH/GLI signaling in melanoma.

    Dermal Bacterial LPS-Stimulation Reduces Susceptibility to Intradermal Trypanosoma brucei Infection

    Scientists showed that although dermal injection of colony stimulating factor 1 increased the local abundance of macrophages in the skin, this did not affect susceptibility to intradermal T. brucei infection.

    Current Views on Neuropeptides in Atopic Dermatitis

    The authors summarizes the mechanisms of several common neuropeptides in atopic dermatitis (AD) and hypothesize that neuropeptides may be the novel potential targets in AD treatment.
