In this case study, the progression of alopecia universalis in a Japanese man was linked to the involvement of Th1 and Th17 cells, suggesting an autoimmune mechanism.

This review discusses the evolution and studies of injection lipolysis for fat reduction, highlighting the need for more research to ensure patient safety and treatment efficacy; it reports no new clinical results.

This review describes the variety of mucocutaneous side effects caused by antineoplastic chemotherapy, with emphasis on skin, nails, and mucous membranes, while highlighting potential severity and the possibility of needing to adjust or interrupt treatment in rare cases; it presents no new clinical results.

This study established a new mouse model for TCE-induced skin sensitization and reported that proinflammatory cytokines TNF-α, IFN-γ, and IL-2 significantly contribute to this sensitization process.

This study found that certain T cell-associated genes were upregulated in dogs with Vogt-Koyanagi-Harada syndrome and vitiligo, suggesting a shared immunopathogenesis with humans.

This review explores recent findings on the regulation of the pilosebaceous unit and reports no new clinical results, emphasizing the emerging understanding of growth factors and steroid hormones in hair growth processes.

This study found that specific gene upregulations and mutations in hidradenitis suppurativa skin support the role of inflammation, altered epithelial differentiation, and metabolism dysregulation in the disease's pathogenesis.

This study found that human placenta hydrolysate effectively inhibited atopic dermatitis development in stimulated human cells and a mouse model, suggesting its potential as a therapeutic agent for related skin diseases.

In this case report, the authors identified giant cell arteritis as the underlying cause of bitemporal hair loss and scalp tenderness in a 70-year-old woman, initially misdiagnosed as age-related symptoms.

In a mouse model, this study found that exposure to PM2.5 leads to significant postpartum hair loss, apparent via morphological changes and elevated markers of inflammation, apoptosis, and fibrosis, potentially exacerbated by changes in hormone receptors and stem cell populations.

In this study, PA-011, a traditional Chinese medicine extract, was shown to improve hair growth in alopecia areata model mice by reducing skin inflammation and altering skin microbiota, indicating its potential therapeutic role for this condition.

This study found that an extract from the herbal medicine Ophioglossum vulgatum Linn. showed potential hair growth promotion and increased ATP and catalase activity in cell assays, suggesting its use in treating alopecia.

Hair shaft miniaturization leads to hair follicle stem cell loss, suggesting Piezo1 as a potential treatment target.

This study analyzed skin biopsies from human monkeypox virus (hMPXV1) cases and found characteristic pustular stage features, including epidermal necrosis, shadow cell appearance, ballooned keratinocytes, and a dense inflammatory infiltrate, expanding histological knowledge crucial for understanding this disease and related Orthopoxvirus infections.

This study determined in-vivo skin damage thresholds for 1319-nm laser exposure in pigs, and the findings may enhance understanding of thermal damage mechanisms and inform laser safety standards.

This study found that the PSEN1-P242LfsX11 mutation in hidradenitis suppurativa influences cytokine and chemokine expression in macrophages, potentially affecting inflammatory responses.

This study found that intracellular Toll-like receptors were significantly up-regulated in peripheral blood mononuclear cells of alopecia areata patients, suggesting a potential role in inflammatory signaling and pathogenesis.

This study found that Acanthus ebracteatus extract and verbascoside induced dermal papilla cell proliferation and reduced inflammatory cytokine release in vitro, suggesting potential for anti-hair loss applications.

This study investigated the effects of nandrolone decanoate on adult rabbits and reported that administering 10 mg/kg for 15 days caused harmful histological changes in the heart, liver, and kidneys, including inflammation and tissue degeneration.

This study found that dogs with dermatitis exhibited specific histological skin changes, such as hyperkeratosis and inflammatory cell infiltration, and showed increased leukocyte counts compared to non-dermatitis dogs.

This study suggests that oleanolic acid may promote hair growth in mice with testosterone-induced androgenetic alopecia by activating the Wnt/β-catenin pathway and influencing various molecular levels.

This study found that excessive consumption of cloves in mice caused toxic changes in the liver, including structural damage and cell death, but concluded these effects are not considered dangerous.

Topical imiquimod is as effective as 5-fluorouracil for treating actinic keratosis, with about a 5% risk of it turning into squamous cell carcinoma.

This study reported that stem cells derived from semi-solid bone marrow improved the healing of diabetic incision wounds in rats by increasing epidermal thickness and blood vessel growth, and reducing hair follicle destruction, cellular penetration, diffuse fibrosis, and necrosis compared to control groups.

This study found that immune cells, including T cells and macrophages, significantly influence stem cell behavior and tissue regeneration by secreting cytokines and inflammatory factors in mice.

This study found that acute stress can cause rapid hair loss by triggering necrosis in hair follicle cells and initiating autoimmunity, revealing a mechanism where stress-induced nerve activity leads to tissue damage and immune system activation.

This review discusses recent advances in how proinflammatory cytokines affect epidermal stem cell function during skin wound healing and introduces potential therapies targeting these cells and cytokines.

This review discusses strategies to enhance mesenchymal stem cell therapy effectiveness but reports no new clinical results; it highlights the need for improved consistency and efficacy in MSC-based treatments.

This study found that dietary yeast cell wall supplementation in broiler chickens increased certain immune responses compared to antibiotic treatments following immunization with sheep red blood cells.

This study suggests that Notch1 acts as a key signal in skin epithelium, promoting immune cell recruitment and aiding in normal skin repair after damage.
