In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

This study observed that while X-ray radiation did not alter major hair keratin composition in mice, it decreased hair follicle stem cell markers and increased Krt5, suggesting potential as a radiation biomarker.

This study found that reduced cell cohesiveness in eccrine sweat gland outgrowths contributed to delayed wound healing in elderly skin compared to younger skin.

This study found that ACKR2 plays a crucial role in reducing inflammatory skin fibrosis and promoting inflammation resolution through IFN‐β production, limiting tissue scarring.

This article reviews the anatomy and pathology of skin and hair to aid in diagnosing skin diseases and discusses potential therapies, without reporting new clinical results.

In this review, the researchers discussed the role of cell wall components and proteins in root hair growth, emphasizing the complex interplay of subcellular factors, and identified open questions and future research directions in root hair mechanobiology.

This review suggests that dermatological cosmetic procedures can be safely performed on dark-complexioned skin with appropriate treatment adjustments, highlighting the need for careful consideration to prevent adverse effects.

This article in Experimental Dermatology does not include an abstract or any new research findings.

This study found that constitutively active Stat3 in transgenic mice led to reduced keratinocyte stem cell populations in hair follicles, altering stem/progenitor cell dynamics and homeostasis.

This review discusses the roles of sebaceous gland activity, Malassezia yeast, and individual susceptibility in scalp flaking disorders, including dandruff and seborrheic dermatitis, but reports no new experiment results.

This study found that anti-TNF therapy-induced alopecia exhibits distinct clinical and histopathological features and can mimic psoriatic alopecia and alopecia areata, with some patients improving with topical treatment.

This review discusses the involvement of type I interferons in skin autoimmune and inflammatory diseases but reports no new clinical results.

This study found that the HoxC gene cluster plays a critical role in the development of ectodermal organs, including hair and nails, with mammalian-specific enhancers increasing transcription levels during development.

This study suggests that co-culturing human outer root sheath cells with human dermal papilla cells can restore their ability to induce hair growth by altering gene expression through paracrine signaling.

This study found no qualitative skin differences during development between mutant hairless USP mice and BALB/c mice, except for enlarged cysts in the hairless strain.

In preclinical studies, a B-Raf inhibitor called WYE-130600 caused dose-related skin effects in dogs and rats, suggesting potential similar responses might occur in humans.

This study observed that feeding ewes a water-soluble complex of fatty acids increased primary hair follicle bulb diameter and mitotic activity, suggesting a positive correlation with wool growth.

This review article discusses recent updates on the skin manifestations associated with thyroid disease, emphasizing their role as early indicators of thyroid hormone dysregulation.

This study found that Stat3 influences the differentiation and migration of keratinocytes, potentially impacting epithelial carcinogenesis, by examining Stat3 activation or deletion effects in mouse models.

This study found that mutant Cx43 impairs fibroblast function during wound healing and reduces hair follicle cell proliferation, likely contributing to hair growth defects in ODDD patients.

This study in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

Lichen planus pigmentosus and fibrosing frontal alopecia in Colombia are likely different stages of the same disease.

In a controlled study, researchers observed that lambs exposed to colder temperatures had increased wool growth, thicker skin, altered physiological traits, and activated specific molecular pathways, highlighting potential targets for enhancing cold tolerance, welfare, and productivity in sheep breeds.

This study suggests that using nanostructured lipid carriers may improve the targeting of 17-α-estradiol in treating alopecia by improving skin penetration and stability.

This study found that down-regulation of sonic hedgehog gene expression is a critical early event in chemotherapy-induced tissue damage in hair and feather follicles.

This review discusses the complex relationship between stress and various skin conditions, highlighting the role of the skin in the stress response and the brain-skin communication pathways, but reports no new research findings.

This review discusses mechanisms of wound healing impairment in leptin-deficient murine models used for diabetic research, and reports no new clinical results; the authors emphasize the need for further study.

New therapies for burn wounds show promise in reducing pain, infection risk, and improving healing and physical outcomes.

In this study, a combined therapy of nicotinamide and green tea polyphenols was reported to improve EGFR inhibitor-related skin toxicity and patient quality of life, suggesting it merits further investigation.

This study found that age-related changes in scalp dermal fibroblasts, including increased MMP-1 and reduced ECM components, may significantly affect the hair follicle environment and contribute to hair aging.
