This study observed that in varicella, the varicella-zoster virus spreads to dermal endothelial cells before reaching keratinocytes, whereas in herpes zoster, it first involves cutaneous nerves and pilosebaceous units.

This review discusses recent advancements in dermatopathology, including molecular biology techniques and diagnostic innovations, and reports no new experimental findings.

This study found that P311 triggers transdifferentiation of epidermal stem cells into myofibroblast-like cells via TGFβ1/Smad signaling during wound healing.

This study found that beta-caryophyllene enhanced re-epithelialization in cutaneous wounds of female mice, suggesting its potential for improving wound healing through multiple pathways.

This review explores the role of macrophage subsets in adult cutaneous wound healing and emphasizes their potential for therapeutic targeting, but reports no new experimental results.

This systematic review synthesizes evidence from the past 20 years to highlight the potential of exosome-based therapies from stem cells and plants in improving cutaneous repair, skin aging, and challenging dermatological conditions through mechanisms like immunomodulation and collagen remodeling.

This review explores the complex, context-specific roles of Wnt/β-catenin signaling in six diabetic complications and suggests that targeted modulation could improve both pathological and functional outcomes.

This systematic review found significant associations between skin disorders like polycystic ovarian syndrome, dermatomyositis, atopic dermatitis, and leprosy with infertility, noting a lack of significant findings for systemic sclerosis.

This report presents a case where multiple steatocystomas appeared in a psoriatic patient during ustekinumab treatment, suggesting the drug may unmask a genetic predisposition to steatocystoma multiplex.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

In this study, researchers found that the histone demethylase UTX is crucial for regulating skin differentiation through retinoic acid signaling, mainly impacting females, as males compensate with a Y-linked paralog.

This study found that phospho-S6 is strongly expressed in malignant hair follicle tumors but only patchily in a minority of benign tumors, indicating a potential marker for distinguishing between the two.

This review highlights the potential benefits of low-level light therapy for treating various alopecias, with reported improvements in hair density and count, especially when combined with minoxidil or finasteride, but it offers no new clinical results.

This study found that nuclear beta-catenin, LEF1, and PHLDA1 expression was conserved in matrical tumors, suggesting a shared tumorigenesis process involving Wnt pathway activation.

This review discusses the potential of JAK inhibitors for treating alopecia areata and reports case study evidence of their effectiveness, but formal clinical trials are needed for more definitive conclusions.

This study concluded that the Wnt signaling pathway does not significantly influence human keratoacanthoma development, but the overexpression of Sox9 suggests alternate signaling involvement.

In this study, mouse sebaceous glands were found to require nerves for growth during active hair cycles, suggesting a nerve-dependent sebaceous gland cycle coordinated with hair growth.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

This study reports that miR-22 promotes cancer progression and metastasis by maintaining Wnt/β-catenin signaling and cancer stem cell function.

This study found that the novel IPC analog SIG-1451 may inhibit inflammatory cytokine release in cell-based assays relevant to allergic dermatitis.

This study found that SM04755, a novel topical drug, inhibited inflammation, keratinocyte proliferation, and fibrosis in vitro and improved skin health in a mouse model of psoriasis, indicating potential as a topical psoriasis treatment.

This review discusses the cutaneous symptoms associated with COVID-19 and their potential use in diagnosing and assessing the severity of the disease, but it reports no new clinical results.

This study found that econazole nitrate delivered via MPEG-dihexPLA micelles significantly increased skin deposition compared to Pevaryl® cream, potentially enhancing drug bioavailability and clinical efficacy.

This review examines the role of nuclear hormone receptors in skin wound repair processes and reports no new clinical results, highlighting the importance of their interaction with skin cells for effective healing.

This review discusses how androgens may regulate wound healing and inflammation, noting that testosterone appears to inhibit healing and promote inflammation, but it reports no new clinical results.

This study revealed that during fetal development, MITF and Mart-1 expressing melanocytes progress from the dermis to the epidermis and hair follicles, with MITF possibly marking follicular stem cells.

This study found that the DexIEME hydrogel promotes complete skin regeneration and scar attenuation in murine and porcine models, suggesting potential for treating deep dermal injuries.

This review explores the role of fatty acids and bioactive lipid mediators in skin health and suggests targeting this metabolic network to control inflammation and improve skin conditions, but it reports no new findings.

This review outlines dermatological toxicities associated with targeted cancer therapies and immunotherapies, emphasizing the need for collaborative management by oncologists and dermatologists but reports no new clinical findings.

This review discusses challenges in managing cutaneous drug reactions to anticonvulsants and reports no new clinical findings; the authors emphasize the complexity of discontinuing or rechallenging suspected agents.
