This review provides guidance on using two-photon microscopy for real-time and long-term visualization of stem cell activity in live mice skin, focusing on its application in researching skin and stem cell biology.

This study found that keratin 19 may be a marker for skin stem cells, helping to characterize these cells in different conditions and potentially explaining variations in healing rates between children and adults.

This study found that oral tofacitinib was effective and well tolerated for treating alopecia areata in most pediatric patients, with nearly 73% experiencing hair regrowth.

TCDD changes skin gene expression and may harm skin health.

This study reported that Trichoscan, a computer-assisted hair measurement system, was not supported as accurate for clinical trials due to errors in signal detection, despite its analysis speed.

This study observes that TYK2 inhibition with BMS-986202 may extend hair follicle growth phases and decrease inflammatory cell markers in alopecia areata, suggesting potential for clinical application.

This study reported that canine recombinant IFNγ (KT‐100) significantly improved atopic dermatitis symptoms in dogs compared to placebo, and it appeared to be safe during the study period.

This case analysis found that trichoscopy is a valuable tool for diagnosing and monitoring treatment progress in tinea capitis by distinguishing between Microsporum and Trichophyton etiologies.

This report from Tangle Teezer and TRI Princeton indicates that their Extra Gentle brush reduces hair breakage by up to 39%, offering a therapeutic experience for users with fragile scalps.

In this study, researchers developed a novel TA-encapsulated microneedle applicator that successfully promoted hair growth and reduced inflammation in a C3H/HeJ mouse model of alopecia areata, potentially offering an improved alternative to existing treatments.

Most patients with Tuberous sclerosis had neurological or skin issues, and over half had psychiatric problems.

This correspondence about the treatment of chronic alopecia areata with tildrakizumab reports no clinical results; the authors present an open-label pilot study setup.

This report expands the known genetic mutations linked to monilethrix by identifying new patients with KRT83 mutations, confirming its role as a causative gene for this hair disorder.

In this case report, a woman with Graham-Little-Piccardi-Lassueur Syndrome and hidradenitis suppurativa showed significant improvements in both conditions after six months of treatment with tofacitinib, a Janus Kinase inhibitor, with no recurrence or adverse events noted during a two-year follow-up.

This analysis examines how faculty-related Instagram accounts have adapted their posts during the recent application cycle, including showcasing credentials and incorporating new virtual engagement tools, but reports no new research findings.

This case report suggests that Trichostasis spinulosa should be considered in diagnosing treatment-resistant open comedone-like lesions and that skin surface biopsy might be an effective diagnostic method.

This report describes two cases of tinea capitis in young siblings, with cultures showing M. canis and Rhodotorulla, and notes improvement after treatment with ketoconazole lotion and shampoo for two months.

In this study, Sox13 was identified as a novel marker for early hair follicle development and differentiation in mice, though it appears to be dispensable for overall epidermal and adnexal development.

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

This study found that rapamycin effectively inhibits TPA-induced keratinocyte proliferation and skin tumor promotion by targeting mTORC1 signaling in both wild-type and transgenic mice.

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.

In this study, researchers found that ex vivo and in vivo administration of the TYK2 inhibitor BMS-986202 prevented immune privilege collapse and promoted hair regrowth in models of alopecia areata, suggesting this approach may offer a new therapeutic avenue deserving of clinical investigation.

This study explored COVID-related chilblains using transcriptomics and found they showed a distinct interferon and JAK/STAT pathway activation, absent in vaccine-related chilblains, with inflammatory cell types varying over time.

This study developed a high-resolution phototrichogram system that can automatically and accurately assess hair growth metrics in cosmetic trials, achieving over 90% correlation with manual measurements.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This study suggests that trichoscopy with a handheld dermatoscope may help differentiate temporal triangular alopecia from other localized alopecia by identifying specific hair features.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This study suggests that the shoulder guard hair of captive sika deer is effective for hair analysis, providing insights into growth patterns and isotopic changes that could aid future research on wild deer using hair samples.

This paper reviews the challenges of treating alopecia areata affecting eyelashes and discusses the risks associated with traditional therapies; it reports no new clinical results.

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.
