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 study reports the successful differentiation of mouse induced pluripotent stem cells into keratinocytes that can regenerate skin and its structures in an in vivo environment.

This review discusses the regulatory roles of type 2 alarmin cytokines in skin immunity, focusing on their implications in host defense, chronic inflammation, and cancer, but reports no new clinical results.

In this study, decreased expression of BMP2 and ephrin A3 and increased NT-4 gene expression were observed in dermal papilla cells from androgenic alopecia-affected skin, suggesting potential roles in hair growth regulation.

Stem cells in mouse nails are found in the nail matrix and may control nail growth.

This study found that actively targeted AN2728-loaded nanocarriers reduced inflammation and improved skin condition in a mouse model of psoriasiform inflammation compared to free drug and non-targeted nanoparticles.

This study found that UVB irradiation alters skin stem cell niches leading to signs of photoaging, which may be reversed by adipose-derived stem cells through BMP4 pathway modulation and niche remodeling.

This study found that epithelial keratin K 6 is associated with hyperkeratotic and ulcerated changes in the gastric pars oesophagea of pigs, suggesting epithelial proliferation plays a role in ulcer development.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

In this study, researchers found that the gene Dkk4 influences color pattern formation in domestic cat fetuses, and its mutation is linked to the Ticked pattern type.

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.

This review analyzes the interplay between atopic dermatitis and alopecia areata, suggesting that epidermal barrier dysfunction and genetic predispositions exacerbate both conditions through immune responses.

This study describes the use of a genetically engineered mouse model, mTurquoise2-Col4a1, to fluorescently label collagen IV and observe basement membrane dynamics during skin development, revealing its stability and pliability during rapid growth phases.

This study found that NIMP-R14-conjugated nanoparticles, loaded with roflumilast, effectively targeted neutrophils to reduce inflammation and improve symptoms in a mouse model of psoriasiform dermatitis, suggesting potential for targeted therapy in autoimmune skin diseases.

This study found that gels containing glycyrrhizic acid and aqueous Glycyrrhiza glabra extract significantly reduced underarm hair growth in terms of area, thickness, length, and number compared to their gel bases.

In this study, Yikgeebohyul-tang promoted faster hair regrowth in C57BL6 mice, potentially linked to changes in cytokine levels and epidermal growth factor expression.

This study found that hair germ and epidermal basal cells differ in keratin expressions in rat hair tissues, with hair-specific keratins appearing after the differentiation of each layer.

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

This study used an autoradiographic technique to observe that germicides in surfactants are primarily deposited on the stratum corneum of guinea-pig and human skin.

This paper presents a protocol for differentiating human-induced pluripotent stem cells into keratinocyte progenitor cells and keratinocytes, suggesting potential applications for hair follicle restoration and burn or ulcer therapy.

In this study, researchers observed that the skin quality and hair follicle development of Rex rabbits improved when slaughtered in winter compared to summer, with findings suggesting seasonal regulation via multiple signaling pathways affecting fur characteristics.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

This study found that FAM19A5 acts as a negative regulator of wound healing by hindering keratinocyte migration and partially transitioning them between epithelial and mesenchymal states, suggesting that targeting the FAM19A5-PPARD-Snail axis could offer new therapeutic options for impaired wound repair.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.

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.

In this study, cashmere goats engineered to overexpress the Tβ4 gene in hair follicles produced more cashmere, indicating that Tβ4 promotes secondary hair follicle development and enhances yield.

The study concluded that fatty acid transport protein 4 in epidermal keratinocytes is crucial for maintaining normal skin structure, as its deficiency led to hyperkeratosis and epidermal barrier disruption in mice.

This case report identified a 4-month-old boy with Menkes disease, a neurodegenerative disorder of copper metabolism, noting symptoms like recurrent seizures, developmental delay, and specific physical characteristics, confirmed by genetic sequencing showing a pathogenic ATP7A mutation and low serum copper and ceruloplasmin levels.

This study found that the methylation level at CpG III site 4 of the KRT17 gene promoter significantly influences wool production in Angora rabbits, suggesting its potential as an epigenetic marker for breeding high wool yield.
