This study observed that patients with acute alopecia areata treated with Janus kinase inhibitors achieved a higher rate of complete hair regrowth by week 24 compared to those with non-acute disease, highlighting the benefits of early intervention.

This study found that Ang1 improved survival and proliferation in human follicle dermal papilla cells under DHT-induced stress, suggesting potential as a therapeutic candidate for androgenetic alopecia.

In this study, researchers identified a cluster of hair-specific keratin-associated protein genes within the 21q22.3 region, revealing a novel transcription mechanism involving TSPEAR/C21orf29 that may bypass typical transcriptional termination sites.

This study found that a highly resistant structure, located at the interface between the cuticle and cortex of human hair, acts as a penetration barrier, which the authors propose to name the "cuticle anchored resistant base" or CARB.

This study found that recombinant human hair keratin proteins K31 and K81 show greater potential for inducing skin cell differentiation compared to natural keratin coatings.

This study revealed that human keratin-associated protein genes are expressed in specific patterns in hair fiber regions and vary in size, with some variations distinct across different populations.

This study found a recurrent nonsense mutation in the HR gene linked to atrichia with papular lesions in two Kashmiri families, suggesting whole exome sequencing as an efficient method for diagnosis and genetic counseling.

This study found that krh/krh rats serve as a suitable model for non-inflammatory acne and that adapalene treatment decreased open comedones and altered lipid metabolism and cytokine production in these rats.

Ritlecitinib may help treat alopecia areata by protecting hair follicles.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This study found that activating cannabinoid receptor 1 reduces the expression of keratins K6 and K16 in human keratinocytes, suggesting potential implications for psoriasis management.

This review discusses the role of the JAK-STAT pathway in autoimmune skin diseases and suggests potential therapeutic benefits of JAK inhibitors, but reports no new experimental results.

This study identifies two previously unreported pathogenic RIPK4 gene variants, suggesting a functional link with cell adhesion molecules in ectodermal dysplasias.

In this study, distinct molecular mechanisms of action were identified for three drugs used in alopecia areata clinical trials, providing insights for precision medicine and treatment selection.

Runx1 helps control the KAP5 gene in human hair follicles.

This case report observed successful hair regrowth with ritlecitinib in a patient with severe alopecia who did not respond to a previous year of baricitinib therapy.

This study developed a genetic toolbox to engineer Cutibacterium acnes for dermal applications, successfully creating a strain that secretes antioxidants to reduce oxidative stress in a UV stress model.

This study found that disrupting Adam10 in the epidermis led to severe skin and multi-organ abnormalities, implicating Adam10 as crucial for proper Notch signaling and skin maintenance.

In this study, ritlecitinib treatment for 12 and 24 weeks downregulated immunity-related genes and upregulated hair keratin genes in patients with alopecia areata, correlating with scalp hair regrowth response.

This study found that the K6/ODC transgenic mouse model is highly sensitive to identifying genotoxic carcinogens, showing 100% concordance with traditional rodent bioassays.

In this study, researchers found that disrupting EGFR signaling in mice led to increased inflammation and hair follicle damage but that inhibiting the JAK-STAT1 pathway could restore hair growth and skin function.

This study found that synthetic RNA and DNA trigger significant increases in certain chemokines in human keratinocytes, predominantly via NF-κB activation, without evidence of alternative splicing, suggesting other regulatory pathways may be involved.

This study found that 1′S-1′-acetoxychavicol acetate from Alpinia galanga inhibits Nox isozymes and suppresses testosterone-induced hair loss in a mouse model of androgenetic alopecia.

This study identified a new ovine KRTAP21-1 gene variant in sheep, with wool yield affected by the variant, suggesting its potential as a genetic marker for improving wool production.

This study identified a new keratin, K6irs, as a potential histological marker for the inner root sheath of hair follicles in mice and humans, and as a candidate gene for hereditary hair defects.

This study found that increased ACE2 expression, prompted by mechanical stretch, promotes skin regeneration and reduces dermal thinning during tissue expansion by enhancing collagen synthesis, suggesting ACE2's potential to improve clinical outcomes in reconstructive surgery settings.

This study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.

This study suggests that lipin-1 plays a crucial role in keratinocyte differentiation by modulating protein kinase C activity through diacylglycerol levels, with implications for skin biology.

RAPK is a rare skin disorder with pigmented spots, mainly on hands and feet, starting in youth.

In this phase 3 trial analysis, baricitinib improved scalp hair growth in adults with severe alopecia areata, with a faster and higher response in those receiving 4 mg compared to 2 mg, but response varied with severity at baseline and continued through week 52.
