This review synthesizes recent molecular and preclinical advances in alopecia areata and androgenetic alopecia, highlighting how interventions targeting specific intracellular signaling pathways and utilizing stem cell technologies can support precision regrowth and structural follicle reconstruction.

This study found that in a human skin organ culture model of pemphigus vulgaris, split formation led to significant upregulation of IFNγ and TNFα-related genes, indicating secondary effects from mechanical stress, not direct changes from autoantibodies.

This study identified five master regulators that mediate molecular differences in hair follicle development and sexual dimorphism in the skin, providing insights into male pattern baldness and hair follicle donor dominance.

This review highlights the limitations of existing hair loss treatments like minoxidil and finasteride and suggests that future therapies may benefit from focusing on antibody and cell-based treatments, which offer targeted and potentially transformative options for managing hair loss disorders.

This research abstract describes alopecia areata as an autoimmune disease causing hair loss due to an inflammatory response mediated by the JAK/STAT signaling pathway. The condition, which affects young people disproportionately, lacks a cure and entails significant psychosocial challenges, despite varied treatment attempts.

This article reviews the JAK signaling pathway and the development of ruxolitinib cream as a targeted treatment for inflammatory skin diseases, reporting no new clinical results.

In this study, researchers used transcriptome sequencing and bioinformatics analysis to identify important genes and pathways involved in the transition between hair growth phases, offering new insights into hair follicle cycle regulation and development.

This study found that TAp63 and ΔNp63 isoforms in the p63 family interact with different transcription factors to regulate distinct transcriptional programs, affecting various biological functions like metabolic pathways, oxidative stress response, and epithelial morphogenesis in mouse epidermal cells.

In this study, researchers found that the SLICK1 allele in cattle may alter local immune regulation, hair growth, and tissue remodeling, as indicated by differential gene expression pathways associated with immune and inflammatory responses in slick vs. nonslick Holsteins.

TEC kinases may help cause inflammation in vitiligo and could be targeted for treatment.

The authors discussed that SOCS1 and SOCS3's inhibition of JAKs plays a significant role in the development of JAK inhibitor drugs for skin inflammatory diseases and malignancies.

This study highlights that ZNF750, a zinc-finger transcription factor, is crucial for epidermal differentiation and barrier formation in skin by activating genes involved in lipid processing and stratum corneum development, and links ZNF750 sequence variations to skin inflammatory diseases like psoriasis.

This manuscript reviews the latest understanding of alopecia areata's pathogenesis, highlighting the roles of genetic, immunological, and environmental factors, with a focus on immune responses involving IFN-γ and cytotoxic CD8+ T-cells as key contributors to hair follicle inflammation and function disruption without follicle destruction.

This review explores the complex factors involved in alopecia areata, such as immune and genetic influences, and discusses advances in diagnostic and therapeutic approaches, while reporting no new clinical results.

In this study, researchers identified specific long non-coding RNAs involved in feather development that do not follow traditional genetic inheritance patterns in chickens.

In this study, a patient with clinically amyopathic dermatomyositis experienced persistent skin issues despite treatment, highlighting questions about type I interferon's role in skin disorders and potential IFN-targeted therapies for cutaneous lupus erythematosus and dermatomyositis.

This systematic review assessed the off-label use of topical Ruxolitinib cream for various skin conditions and found it effective for lichenoid and granulomatous dermatoses, though results for alopecia areata were inconsistent. The authors indicate that further research is warranted to confirm these findings.

This review summarizes the potential of single traditional Chinese medicines and extracts in preventing and treating renal fibrosis, emphasizing their capacity to inhibit transforming growth factor β and reduce extracellular matrix formation, but it reports no new clinical results.

This single-patient case study reported promising results for severe, corticosteroid-resistant alopecia areata, with treatment using exosomes derived from mesenchymal stromal cells leading to almost complete hair regrowth in 12 weeks and favorable changes in inflammatory markers, suggesting potential for further investigation.

This review reports that Dang Gui (Radix Angelica sinensis) possesses bidirectional immunoregulatory effects, enhancing immune cell proliferation and function, and may benefit immune-related diseases such as cancer and anemia. It also evaluates regulatory and safety aspects, aiming to guide future research and clinical use.

This study found distinct expression patterns of various transcription types during hair follicle morphogenesis, providing a foundation for understanding hair development mechanisms and aiding selective breeding for desirable wool traits in a specific breed.

This study identified and characterized several long noncoding RNAs in Cashmere goats, revealing complex regulatory roles in hair follicle development and growth, particularly within the Wnt signaling pathway.

This study concluded that the Wnt signaling pathway does not significantly influence human keratoacanthoma development, but the overexpression of Sox9 suggests alternate signaling involvement.

This source reviews mechanisms and existing treatments for hair aging, highlighting factors like oxidative stress and DNA repair defects that affect hair follicle and stem cell function, and discusses research limitations and future directions in the field.

This review investigates molecular mechanisms behind PCOS pathogenesis and discusses potential therapies, but reports no new clinical results.

This study identified key genes and signaling pathways involved in cashmere goat hair follicle growth cycles, influenced by melatonin implantation, suggesting a basis for further research on melatonin's regulatory mechanism.

This study identified distinct plasma miRNA profiles in alopecia areata that may aid in diagnosis and therapy, but further validation is needed to confirm these exploratory findings.

This study reviewed literature on signaling pathways and concluded that these pathways are crucial pharmacological targets, influencing the mechanisms of drugs used in neurological, cardiovascular, and oncological treatments to correct signal transmission disturbances.

This study found that mice lacking the Vitamin D receptor showed disrupted hair follicle cycling, which was partially restored with hedgehog signaling pathway activation, suggesting a role for this pathway in follicle regulation independent of vitamin D.

This study found that human outer root sheath cells express VEGF receptor-2, and exogenous VEGF165 significantly stimulates their proliferation through activation of the ERK signaling pathway.
