This research observed that removing RNase L in mice enhances regenerative capacity through increased IL-36 and wound-induced hair neogenesis, highlighting RNase L as a gene that represses regeneration by moderating immune responses during viral infections.

In this study, nearly one-third of patients with severe alopecia areata treated with ritlecitinib achieved complete scalp hair regrowth at least once over three years, and most maintained regrowth or stayed at low hair loss levels subsequently.

This study found that patients with severe alopecia areata are willing to accept increased risks of serious infection, cancer, and blood clots when opting for a higher dose of ritlecitinib, valuing the potential for greater hair regrowth efficacy compared to a lower dose.

This study found that the plant-growth-promoting bacteria Azospirillum brasilense enhances root hair development by increasing auxin levels and activating specific transcription factors, highlighting key signaling pathways involved in this process.

In this study, researchers found that a positive feedback loop involving Ca 2+ and RHD2 NADPH oxidase-derived ROS helps maintain growth sites, crucial for root hair development and cell shape in Arabidopsis thaliana.

Ritlecitinib helps regrow hair in alopecia areata and is safe for long-term use.

Ritlecitinib helps regrow hair in alopecia areata and is safe for long-term use.

Ritlecitinib works well and is safe for treating alopecia areata.

In this study, oral administration of ginsenoside Rf from Panax ginseng promoted hair regrowth and increased hair thickness in a mouse model of androgenetic alopecia by enhancing androgen receptor degradation, highlighting its potential for cosmetic and functional food applications.

This study suggests that a specific short sequence repeat in Malassezia restricta may be linked to increased colonization and the development or exacerbation of androgenetic alopecia.

The trial is ongoing, but researchers are evaluating the efficacy and safety of REZPEG, a potential new therapy for severe alopecia areata, which selectively expands regulatory T cells.

This case report describes a rare aggressive variant of squamous cell carcinoma on the scalp of a non-immunosuppressed older male, highlighting its high biological risk for metastasis and poor outcomes.

This study evaluates the efficacy and safety of a higher dose (100-mg) of ritlecitinib for treating severe alopecia areata, comparing it to external and synthetic placebo control groups.

In a single-center study, adolescents with moderate-to-severe alopecia areata treated with ritlecitinib 50 mg daily for 24 weeks showed significant hair regrowth, with 27.3% achieving near-complete regrowth and 45.5% substantial improvement, without serious safety concerns, according to these researchers.

In this study, patients with treatment-refractory alopecia areata who received oral ritlecitinib 50 mg daily experienced significant hair regrowth, with 52.6% achieving complete scalp regrowth and improved Severity of Alopecia Tool scores, indicating its potential effectiveness in real-world settings.

This study found that vitamin A treatment in rats reduced hyperplastic-dysplastic changes and sebaceous gland hypertrophy associated with 3,4-benzpyrene-induced tumors.

This research suggests that the barley protein RACB supports cell polarity functions rather than interfering with immunity, as it aids nucleus positioning during fungal attack rather than affecting early immune responses.

This study reported that a newly developed hydrogel patch, designed to recruit regulatory T cells through ROS-triggered release of CCL22, improved wound healing and hair follicle regeneration in a diabetic mouse model by scavenging ROS, thereby protecting Tregs and suppressing Th17 cells.

This review discusses microneedling radiofrequency in cosmetic dermatology, particularly for skin texture improvement and various conditions, and reports no new clinical results.

This study found that the clionasterol-rich hexane fraction of Caulerpa racemosa may protect against particulate matter-induced skin damage by reducing oxidative stress and mitochondrial-mediated apoptosis in human keratinocytes and zebrafish.

This study found that rice bran supercritical CO₂ extract was classified as a non-irritant for ocular use but a moderate irritant for dermal use in rabbits and guinea pigs.

In this study, the authors reported that AtRXR3, a phosphorus-inducible DUF506 protein, modulates root hair growth under phosphorus stress by interacting with calmodulin and influencing calcium oscillations.

This study found that ureteroileal anastomosis with direct intraluminal visualization had a 4.2% stricture rate, which compares favorably to other techniques with rates between 3.5% and 11.1%.

In this prospective study, ritlecitinib effectively reduced hair loss in patients with severe alopecia areata, with 43.3% of participants achieving a 20 or lower SALT score by week 24, and showed a good midterm safety profile.

In this study, researchers found that the efflux of calcium in root hairs of Arabidopsis thaliana, particularly through the ER-localized ACA2 and ACA7, is crucial for modulating cytoplasmic calcium signals and enabling proper root hair growth, with disruptions leading to impaired elongation.

This study found that unripe Rubus occidentalis extracts may inhibit benign prostatic hyperplasia development in a rat model by reducing prostate weight and androgen-related gene expression.

This study introduced a new adaptive microrhizotron for non-destructive observation of pepper root traits, finding that specific installation patterns significantly enhanced root interception probability while effectively measuring root architecture for plant research.

This study found that RXRα plays a critical role in hair cycling and keratinocyte functions in mice, likely through its interaction with VDR in epidermal cells.

This review highlights the role of reactive oxygen species in root hair growth and cell expansion in plants but does not report new empirical findings.
