This article reviews the differences in inflammatory processes between alopecia universalis and atopic dermatitis, focusing on type 1 and type 2 immune responses, but it reports no new results.

In this study, researchers analyzed over 5,000 T cells per sample using scRNA+TCR-seq technology and found that dual TCR Tregs are present in high proportions across various mouse tissues, showing unique TCR pairing patterns, V(D)J usage, and mRNA expression compared to single TCR Tregs.

This study found that exogenous EGF inhibited hair follicle development and decreased follicle density in both Tabby and normal mice, suggesting interactions between EGF and the Ta peptide influence normal skin phenotype.

This study found a severe MBTPS2 gene mutation in a Japanese IFAP syndrome patient, suggesting other factors may influence the syndrome's clinical features compared to previously studied patients.

This review discusses the role of the CXXC5 protein as a transcription factor and signaling coordinator, noting its involvement in embryonic development, tissue homeostasis, and diseases such as tumorigenesis, but reports no new experimental findings.

This study demonstrates that human epidermal stem cells can adapt to environmental temperature changes through mTOR signaling, and prolonged inhibition of mTORC1 supports stem cell maintenance, which may be vital for regenerative medicine.

This study found that inhibiting the Mitochondrial Pyruvate Carrier in human hair follicles ex vivo activated the integrated stress response, affecting cell proliferation and metabolism.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

JAK inhibitors might help treat alopecia areata.

In this study, the researchers reported that Krox20 plays a crucial role in epidermal homeostasis and hair development, influencing stem cell maintenance and cell survival through the modulation of cellular pathways.

This study found that BMP2 and BMPR-IA inhibited, while Noggin promoted, hair follicle growth in yaks by affecting skin epithelial cell activity.

This study found that over- and ectopic-expression of FoxN1 in early life negatively affected the development of thymic epithelial cells, T and B cells, and skin epithelial cells.

This study found that HtrA2 inactivation in mnd2 mice is associated with delayed hair cycle phases and growth retardation of adipocytes, suggesting HtrA2's role in regulating adipogenesis-related hair growth.

This study found that KRT6A expression increases after epidermal barrier disruption, worsening skin inflammation in disease conditions, and suggests that targeting KRT6A could offer a new treatment approach for inflammatory skin diseases linked to epidermal dysfunction.

LRIG1 protein affects hair growth by regulating skin receptors, leading to hair loss when overexpressed.

This study identified a new FAK isoform, FAKΔe4, which is regulated by ECM stiffness and affects cell migration, invasion, and mechanosensing in human-derived data and engineered models.

This study found that applying topical thymidine dinucleotide (pTT) to newborn mice before UV exposure delayed and reduced melanoma development compared to untreated controls.

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

This study found that the JAK1 rs310241 AG genotype is associated with a 4.6-fold increased risk of alopecia areata, whereas JAK2 polymorphisms showed no significant link, suggesting a potential genetic susceptibility factor warranting further research.

This study in mutant mice found that Bmpr2 and Acvr2a are individually redundant, but together essential for normal hair follicle development, with their reduction causing rapid hair cycling and graying.

CTP-543 effectively promotes hair regrowth in adults with moderate to severe alopecia areata.

This study suggests that autophagy is essential for regulating TLR3-mediated regenerative processes in human keratinocytes.

This study identified genetic loci and pathways associated with long hair growth in the Tianzhu white yak, providing new insights into the genetic mechanisms of this trait.

This review discusses the roles of human tissue kallikreins in skin physiology and pathology and reports no new findings, emphasizing their potential involvement in various skin functions and conditions.

This study analyzed blood samples from individuals with alopecia areata and found that NKG2D+ immune cells, particularly memory-like NK cells, may better correlate with disease activity compared to CD8+ cells, though significant variability among individuals complicates these findings.

This study demonstrated that de novo designed bifunctional proteins can target and degrade BCL-xL, leading to cell apoptosis, suggesting a new approach to targeted protein degradation therapy.

This study found that VEGFR-2 activation may play a role in hair follicle differentiation, proliferation, and apoptosis by co-expressing with several key proteins in normal human scalp skin.
