This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

This review discusses the role of regulatory T cells in skin, including their impact on hair follicle regeneration, wound healing, and immune tolerance, without presenting new clinical findings.

This study suggests that CD8+ cytotoxic T lymphocytes play a crucial role in the development of alopecia areata, based on observations in rodent models that mimic human autoimmune disease.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.

In this study, researchers identified two distinct homozygous mutations in the KRT85 gene among consanguineous Pakistani families with pure hair and nail ectodermal dysplasia, highlighting variations in severity and potential impacts on the K85 protein function.

This study found that using an antimicrobial lotion for 18 months may reduce inflammation and potentially partially reverse hair loss in men with androgenetic alopecia.

This study concluded that hair follicle hyperplasia found in pseudolymphomatous folliculitis can also occur in genuine cutaneous lymphomas, potentially as a coincidental result of underlying pathological processes.

This study found that T-regulatory cells, specifically the FOXP3 CD39 subset, were significantly reduced in both circulation and hair follicles of alopecia areata patients compared to healthy subjects, suggesting potential therapeutic targets.

ICL is a condition with low CD4+ T cells like AIDS but not caused by HIV, and normal CD4+ T cell counts may vary between men and women.

This study found that DHT treatment led to reduced cell growth, increased cell death, cell cycle arrest, ROS production, and senescence in normal human dermal papilla cells, potentially mediated by altered miRNA expression.

Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.

This case report documents a 30-year-old man's presentation with actinic superficial folliculitis and characterizes the inflammatory infiltrate, supporting the classification of this condition as a distinct disease entity.

This article reviews the development and use of induced pluripotent stem cell models and artificial organoids for studying neurodevelopmental disorders, but it reports no new clinical findings.

This article presents a case of primary adrenal localization of non-Hodgkin's lymphoma in a 70-year-old woman, detailing her diagnosis and treatment, with no signs of recurrent disease after polychemotherapy and radiotherapy.

This study found that deleting Snai2 and Snai3 genes in mice disrupts immune cell development, resulting in severe autoimmunity and early death due to the loss of immune tolerance.

This review examines recent findings on COVID-19 pneumonia treatment using mesenchymal stem cells and reports no new clinical results; the authors highlight MSCs' potential due to their immunomodulatory and tissue-regenerative properties.

This study found that combining adipose-derived mesenchymal stromal cells with meglumine antimoniate reduced lesion size and parasite load in mice with leishmaniasis, suggesting potential for improved treatment.

This systematic review and meta-analysis found 30 genetic loci associated with skin ageing phenotypes, noting shared biological pathways in aspects like pigmentation and wrinkling; researchers suggest further studies targeting the same SNP across populations could clarify these associations.

This report describes a rare case of severe combined immunodeficiency caused by a FOXN1 gene variant, complicated by Epstein-Barr virus infection and high-grade B-cell lymphoma, leading to the infant's death despite treatment efforts.

This study found that injecting xeno-free, three-dimensional cell masses from human adipose-derived stem cells improved blood perfusion and preserved limb function in mice without causing tumors or toxicity, suggesting potential for treating severe ischemic diseases.

This review discusses Omenn syndrome, a form of severe combined immunodeficiency, highlighting its immunopathology and genetic defects without presenting new clinical results.

This study found that centrosome ablation in developing epidermis triggers cell surveillance pathways, resulting in thinner skin and halted hair follicle growth, while later stages of epidermal growth may operate independently of basal progenitor division orientation.

This study found that the once-daily gel combining calcipotriene and betamethasone dipropionate was more effective and faster in treating scalp psoriasis compared to individual treatments, with a similar safety profile.

This review discusses the potential of small extracellular vesicles (sEVs) as next-generation therapeutics, noting their ability to overcome biological barriers and modulate cellular environments for various diseases.

This study demonstrated that in mice, the absence of Jagged-1 expression in skin-resident regulatory T cells significantly delays wound healing by reducing the accumulation of neutrophils, highlighting the role of Jagged-1 in coordinating immune cell recruitment during injury.

This study investigated the possible role of neutrophil extracellular traps in contributing to fibrosis in stenotic Crohn's disease.

The abstract reports that non-cultured cellular grafting has become a prevalent and cost-effective method for treating stable vitiligo, with safety and effectiveness confirmed by two decades of studies. It critiques strict legislative oversight, suggesting it might unnecessarily increase costs and limit patient access.

In this study, botulinum toxin type A injections reduced the severity of treatment-resistant scalp psoriasis in more patients compared to placebo over a 12-week period.

This study found that fetal canine hair follicle-derived stem cells exhibited pluripotency markers, suggesting potential for therapeutic applications in hair and skin repair.
