This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

In this study using a mouse model, RIPK1 inhibitors were found to delay the onset of alopecia areata, reduce immune cell numbers in affected skin, and increase hair length, indicating a potential therapeutic role in preventing alopecia areata.

This study found that ANXA1 may influence hair growth in mice by regulating hair follicle stem cell proliferation through the EGF signaling pathway.

In this study, researchers identified two new keratin-associated proteins, hKAP1.6 and hKAP1.7, in human hair follicles, contributing to understanding hair fiber differentiation.

This study shows that IKZF1 and the protein IKAROS may play a role in the development of alopecia areata, based on findings from both mouse models and human scalp tissues.

This study reports that the monoclonal antibody BKN-1 specifically stained basal cell epithelioma cells and certain normal skin structures, indicating a similarity in keratin expression between the tumor and follicular epithelium below the isthmus portion.

This study identified a specific genetic variant in the CCHCR1 gene that may contribute to alopecia areata through impaired keratinization, suggesting an alternative mechanism beyond autoimmune causes.

This study found that JAK1 and JAK3 inhibitors effectively reversed alopecia in a mouse model of AA by reducing skin inflammation, while JAK2 inhibition did not promote hair regrowth.

This study identified a monoclonal antibody, HKN-2, that recognizes specific cells in human skin and may indicate a common antigenic determinant between hair and other skin epithelial tissues.

This article proposes an updated naming system for keratin-associated proteins and genes, aiming to improve data storage and retrieval by including species information and genetic variation.

This case report suggests that starting selective Janus kinase 1 inhibition may improve alopecia in a patient with rheumatoid arthritis who was not responding to TNF-α inhibitor therapy and corticosteroids.

This study identified a key Arabidopsis thaliana gene, TIP1, whose product is involved in S-acylation crucial for normal plant cell growth, particularly affecting root hair development.

In this study, AgK114 was found to be transiently induced in hamster epidermal keratinocytes following skin damage, suggesting its role in the recovery process after injury.

TRIV-509 quickly improves skin barrier and cell health in atopic dermatitis.

This source describes SH‑1 as a next-generation androgen receptor antagonist designed for localized treatment of androgenetic alopecia, aiming to reverse follicular miniaturization while maintaining endocrine balance. Unlike traditional therapies, SH‑1 offers tissue-specific action, avoiding systemic effects.

This study found that inhibiting AP1 transcription factor activity in the suprabasal epidermis of mice alters keratinocyte gene expression, reducing barrier integrity and mimicking human keratoderma.

In this study, researchers evaluated CS12192, a selective JAK3 inhibitor, in an alopecia areata mouse model and found it reversed hair growth inhibition comparably to baricitinib, with better safety and similar immune-modulating mechanisms.

In this case report, a 28-year-old male with severe atopic dermatitis, prurigo nodularis-like lesions, and alopecia areata showed rapid improvements in skin and hair following treatment with the JAK1 inhibitor, ivarmacitinib, suggesting its potential benefit for complex AD phenotypes with immune-mediated hair loss.

This study found that conditional deletion of CD271 in mouse epidermis led to significant disorganization and increased thickness, suggesting CD271's crucial role in regulating skin differentiation and structure.

This study found that loss of the ACER1 gene in mice led to increased ceramide levels and progressive hair loss, highlighting ACER1's role in maintaining hair follicle stem cell homeostasis.

Arg1+ macrophages may play a role in Alopecia Areata, offering new treatment targets.

This case study reports that a 15-year-old male with multiple autoimmune conditions showed significant improvement in skin and gastrointestinal symptoms, along with hair regrowth, after 16 weeks of treatment with the JAK-1 inhibitor upadacitinib, demonstrating its potential in managing complex autoimmune disorders.

This study found that PKCα activation in transgenic mice induces keratinocyte apoptosis and mediates neutrophilic skin inflammation via different pathways, suggesting potential mechanisms for cutaneous inflammatory diseases.

This study found that the OXI1 gene in Arabidopsis thaliana is vital for activating key protein kinases and is necessary for oxidative burst signal responses like pathogen resistance and root hair growth.

This study found that the enzyme A20 helps regulate EDAR-induced NF-κB signaling in mice, preventing ectodermal abnormalities like disheveled hair and assuring proper skin and appendage development.

This study found that JAK1 and JAK2 inhibitors increase β-catenin activity in human hair follicle cells, suggesting an additional therapeutic mechanism for treating severe alopecia areata.

This study suggests that the mechanical robustness of hair may be enhanced by the binding interactions of keratin-associated proteins, particularly KAP8.1, with intermediate filament proteins.

Abrocitinib may help treat alopecia areata effectively with mild side effects.

This study found that alopecia areata patients with a CCHCR1 gene variant had higher recurrence rates and structural abnormalities in hair compared to those without the variant.
