This study found that a recessive mutation in the RHD4 gene of Arabidopsis thaliana leads to slower and more variable tip growth in seedling root hairs, resulting in shorter and wider hairs than in wild-type plants.

This study describes the expression patterns of type I inner root sheath keratin proteins K25–K28 in human hair follicles, highlighting their distinct distribution within different layers.

In this report, oral baricitinib improved both alopecia areata and immune thrombocytopenia in a 56-year-old patient, suggesting a potential dual benefit for these conditions, although regular platelet monitoring and hematology consultation are recommended.

This study suggests that folliculin, mutated in Birt–Hogg–Dubé syndrome, and its partner FNIP1 may play a role in energy and nutrient sensing through the AMPK and mTOR pathways.

This article reports on a partial regrowth of scalp hair in a patient treated with extracorporeal photochemotherapy and interferon α 2a, but provides no new clinical outcomes.

This study reveals that CSPG4-positive basal cell keratinocytes show distinct global gene expression from CSPG4-negative cells, despite similar colony-forming efficiency.

In this study, researchers found that ritlecitinib 50 mg offered a lower cost per responder than baricitinib 2 or 4 mg at both 24 and 52 weeks for treating severe alopecia areata, suggesting potential implications for reimbursement or formulary decisions.

This article is a statement from Robert Niedbalski, president of the American Board of Hair Restoration Surgery for 2018, and contains no new research findings.

Baricitinib is effective for severe alopecia areata with manageable side effects, mainly upper respiratory infections.

This study found that ICAM-1 expression in murine skin is developmentally regulated and crucial for skin and hair follicle remodeling beyond its recognized role in immune responses.

This study identified a mutant in Arabidopsis with shorter root hairs due to early growth cessation, implicating the IRE gene in regulating root hair growth duration.

This study found that Ifidancitinib, a JAK1/3 inhibitor, significantly promoted hair regrowth and reduced inflammation in a mouse model of alopecia areata by decreasing pathogenic T cell activity and inducing T cell exhaustion.

This article features a profile of the ABHRS/IBHRS as part of a series on regional societies and reports no new clinical findings.

The study found that IPI-926 was well tolerated up to 160 mg once daily for 28-day cycles and showed activity as a single-agent treatment in Hedgehog pathway inhibitor-naïve patients with basal cell carcinoma.

This study found that alopecia areata was associated with increased serum levels of retinol-binding protein-4 compared to controls, but no correlation with disease severity was observed.

This study found that overexpression and knockdown of DKK4 influence genes involved in hair follicle growth and development in Angora rabbits and identified specific SNPs in DKK4 associated with wool quality, notably showing that the TT/GG haplotype combination relates to higher fibre diameters.

The researchers reported that topical tofacitinib in mice increased hair follicles in the growth phase and boosted noggin and BMP4 mRNA expressions, compared to a vehicle and minoxidil.

EBF1 controls hair type and length.

This study observed that baricitinib treatment led to significant improvement in a patient's alopecia areata symptoms and suggests further clinical trials to explore its potential as a treatment.

In this study, researchers found that the protein eIF4E is crucial for keratinocyte proliferation in psoriasis, suggesting it as a potential treatment target for the condition.

This study found that overexpression of sFRP4 in skin cells reduces Wnt signaling activation, leading to decreased melanocyte differentiation in regenerating hair follicles.

This study developed a new STR typing strategy for forensic casework, enabling the simultaneous analysis of 11 polymorphic systems, particularly useful for limited or degraded DNA samples such as telogen hair roots.

In this study, the KPAI and KP-IGA scoring systems for assessing keratosis pilaris showed excellent interrater and intrarater reliability, offering standardized measures for clinical and research use.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This study found that in Arabidopsis seedlings, tonoplast intrinsic proteins are targeted to the vacuole via at least two pathways, including pathways with differing sensitivity to a chemical inhibitor that affect root hair growth and PIN2 targeting.

This study identified a specific SNP in the CACNB4 gene associated with a higher risk of chemotherapy-induced alopecia in breast cancer patients, which may help develop interventions to improve their quality of life.

Women with idiopathic hirsutism and PCOS have higher RBP4 levels, and PCOS is linked to greater insulin resistance; weight management may help both conditions.

In this study, 40.9% of patients taking 4 mg baricitinib and 21.2% taking 2 mg achieved significant hair regrowth over 52 weeks, indicating potential long-term benefits for adults with severe alopecia areata without introducing new safety concerns.
