This study reviewed evidence on biologic drugs targeting immune cells for alopecia areata, finding mixed results: some achieved case-level hair regrowth, but controlled trials often showed limited efficacy.

This case report describes a 22-month-old with alopecia universalis who showed improved hair growth after receiving combination therapy with minoxidil, corticosteroids, and excimer laser.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study found that transgenic cashmere goats overexpressing thymosin beta-4 have a higher secondary to primary hair follicle ratio, suggesting potential for increased cashmere yield.

This review discusses the use, efficiency, and preparation methods of autologous platelet concentrates in wound healing and periodontal regeneration, but it reports no new clinical findings.

This study found that the WIF1 gene may play a crucial role in hair follicle growth and development in Angora rabbits by regulating specific genes and proteins.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

In this case report, a three-generation family with Gorlin-Goltz syndrome showed a heterozygous PTCH1 splice-donor variant associated with the disease, and two affected relatives benefited from individualized, side-effect-guided dosing of the drug sonidegib, experiencing regression of basal cell carcinoma lesions.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This article reviews the therapeutic use of interferons and other cytokines in various viral, tumorous, and inflammatory diseases, discussing their biological effects and potential future applications without presenting new experimental results.

This review discusses the plasticity of stem cell populations and their ability to switch between functions for tissue homeostasis and regeneration, emphasizing environmental and hormonal influences, and reports no new results.

Hidradenitis Suppurativa is a chronic skin condition best treated early with surgery for better outcomes and less recurrence.

COL17A1 is crucial for preventing hair graying and loss by supporting hair and pigment stem cells.

This study found that monocytes/macrophages with a pro-inflammatory M1-like phenotype may play a crucial role in the pathogenesis of hidradenitis suppurativa, suggesting potential therapeutic targets.

This study found that tdDPC-EVs significantly improved wound healing by enhancing angiogenesis through the KLF4/VEGFA axis, offering advantages over traditional DPC-EVs.

This study found that extracts from Cirsium japonicum var. spinossimum seeds are rich in polyphenols and flavonoids, demonstrating significant anti-inflammatory and cell proliferation effects in specific cell models, suggesting potential as a source for anti-inflammatory and anticancer agents.

This article reviews the role of skin appendages in wound healing and appendage regeneration, discussing cellular and molecular mechanisms but reports no new experimental findings.

This study found that pro-inflammatory cytokines and apoptotic mechanisms, specifically involving granzyme B and Fas pathways, are associated with chronic alopecia areata, indicating their potential role in the disease's persistence.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This case report details an occurrence of Vogt-Koyanagi-Harada disease during pegylated interferon-α2b and ribavirin therapy for chronic hepatitis C.

This study reports a new association of follicular mucinosis occurring in a patient with Sézary syndrome.

This study found that glycolysis in Paneth cells provides lactate to support mitochondrial oxidative phosphorylation in intestinal stem cells, aiding their function and differentiation.

This study found that in mice, low-dose irradiation causes stem cells in hair follicles to undergo chromatin alterations, which may eventually lead to long-term functional loss in tissues or organs.

This study found that upcycled postbiotic cell-free supernatants from Limosilactobacillus fermentum MG901 and MG4237 protected human dermal papilla cells from oxidative stress, enhancing wound-healing capacity and mitochondrial function, suggesting potential as a sustainable cosmetic ingredient for hair loss alleviation.

This study found that the 15-PGDH inhibitor DPP improved endothelial function in hair-related cells exposed to DHT by reducing oxidative stress and enhancing angiogenic capacity.

This study observed that different alkaline buffers had a significant impact on the volume of liquid consumed by fall armyworm larvae, emphasizing the importance of measuring imbibed volumes to reduce dose errors in bioassays.

This study identified CD28, GZMB, and CD1C as key immune regulators in alopecia areata, highlighting CD28 as a potential therapeutic target with a promising safety profile, using a proteome-anchored multi-omics approach to uncover actionable targets for this autoimmune hair-loss disorder.

This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.
