In this study, rabies virus antigens were detected in the outer root sheath of the follicle-sinus complex in the muzzle skin of rabid dogs, suggesting its usefulness as an alternative diagnostic specimen.

This study found that Sox10 may play a role in early hair follicle development and cycling, as it is expressed in specific regions of the hair follicle during different phases of the hair cycle in mice.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

In this study, researchers demonstrated that human hair follicle outer root sheath cells release ATP, serotonin, and histamine in response to mechanical stimulation, which subsequently activates surrounding sensory neurons.

This study identified a new genetic variant in the KRT71 gene responsible for a breed-specific form of hypotrichosis in Hereford cattle, potentially serving as a model for similar human conditions.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

Ingrown hairs are a common feature in scarring alopecias due to follicular damage.

The authors report a rare case of trichilemmal carcinoma in the thigh of a 71-year-old, emphasizing the importance of complete surgical excision to prevent recurrence and support patient prognosis.

This study identified four ferroptosis-related genes, SLC40A1, LCN2, CREB5, and SLC7A11, as potential diagnostic markers for alopecia areata, revealing reduced expression in affected patients compared to controls, with a predictive model showing high accuracy in differentiating the condition.

This review explores the complex interactions of intrinsic and extrinsic mechanisms that regulate hair follicle stem cells and their role in skin homeostasis, aiming to advance understanding that could support future research on skin disorders.

In this study, researchers observed significant morphological and histological differences in transplanted hair follicles compared to native donor follicles post-FUE hair transplantation for androgenetic alopecia, highlighting substantial variations in sebaceous gland and root sheath degeneration at the recipient site.

This study found that genetic ablation of Tet genes in mice led to changes in hair structure and keratin gene expression, indicating a role for Tet-mediated 5hmC DNA oxidation in hair follicle development and cycling.

In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This review discusses loose anagen hair syndrome, a benign and self-limited condition predominantly affecting children, and highlights the importance of differentiating it from other hair disorders like telogen effluvium and trichotillomania, but reports no new results.

This study found that Tcf3 and Lef1 differently regulate cell differentiation in multipotent skin stem cells, with Tcf3 promoting follicle-like features and Lef1, when modified, promoting sebocyte differentiation.

This study investigated various proteins as eco-friendly hair perming agents for Asian hair and found that bovine serum albumin and keratin achieved perming results comparable to commercial products, while also increasing hair moisture, indicating a protective effect during heat styling.

This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

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.

This study found that external and internal luteolin treatments reduced hair graying in model mice by mitigating age-related dysfunction in hair stem cell signaling, suggesting potential practical applications for anti-graying treatment in humans.

This microscopy study examined the non-keratinous regions of human hair fibers, revealing detailed morphology that could help understand how external influences affect hair structure.

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 review discusses the characteristics and diagnosis of loose anagen hair syndrome in children and reports no new clinical results.

This study found that Keratin 26 is expressed differently in hair follicle phases, particularly during catagen and telogen, influencing cashmere growth and interacting antagonistically with the BMP signaling pathway.

In this study, researchers detailed how hair follicles regenerate after microsurgical amputation, observing a wound reaction involving dynamic dermal-epidermal interactions and changes in extracellular matrix components.

The girl's "dandruff" was actually harmless hair casts, not a hygiene issue.

More research is needed to understand how hair keratins work and their role in hair disorders.

This study found that red light accelerated the transition from the resting to growth phase in hair follicles faster than green and blue light in mice, suggesting it may stimulate hair growth.

This study found that the orphan protein Plet-1 is expressed in specific keratinocytes of mouse hair follicles and may regulate keratinocyte interactions with inert tissues by affecting migration and adhesion.

The researchers reported that scaffoldin, a protein identified in chicken embryos, likely plays a role in forming periderm granules and contributes to the soft cornification of embryonic epidermis.
