This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This study suggests that the T allele of the SNP rs2476601 in the PTPN22 gene may increase the risk of alopecia areata, although further studies are necessary to validate this finding across different populations.

This study observed that expanding regulatory T cells in the skin of mice with alopecia areata did not reverse the condition, indicating that additional immunotherapy may be necessary.

This study observed that NSG-hu-BLT mice developed graft-versus-host disease characterized by CD8+ T lymphocyte-related cell death in the skin and liver, which may affect their utility in other research areas.

This review summarizes recent findings about the multi-site differentiation of tissue regulatory T cells, emphasizing the pivotal role of epigenetic remodeling, but it reports no new clinical results.

This study identified a four-gene loop as a non-invasive biomarker that selectively activates in alopecia areata, providing a precise target for JAK inhibitor treatments.

This review discusses the potential of JAK inhibitors as a promising treatment strategy for alopecia areata, highlighting their mechanism and recent FDA approval based on clinical trial efficacy.

This review highlights the need for a deeper understanding of the genetic mechanisms in alopecia areata to develop evidence-based treatments, but it provides no new experimental results.

This review discusses immune pathways involved in alopecia areata and explores emerging, more targeted therapeutic strategies, noting their potential for better safety and effectiveness compared to traditional immune suppressants.

This study found that alopecia areata is linked to genetic factors, specifically HLA haplotypes on chromosome 6, and involves immune privilege collapse at hair follicles which is mediated by the JAK-STAT pathway and pro-inflammatory cytokines like IFN-γ.

The study was retracted.

In this study, researchers found that the rs3118470 mutation in the IL2RA gene significantly increases the risk of developing alopecia areata, and they emphasize the need for future research with larger, more diverse populations to validate these results.

This review discusses recent advances in the treatment of alopecia areata, highlighting new potential therapies like JAK inhibitors and PRP, and reports no new clinical results.

Certain immune cells in atopic dermatitis skin could be targeted for treatment.

This study reports the creation of rat liver stem cell lines that can differentiate into hepatocytes and suggests they might be useful for pharmacological and regenerative medicine applications.

This study found that in immunodeficient mice lacking T cells, certain innate lymphoid cell subsets increased and influenced the hair growth cycle, with specific ILC subsets shown to promote anagen, the active phase of hair growth.

This study examined molecular predictors of ritlecitinib efficacy in treating alopecia areata, highlighting the role of JAK3-dependent inflammation and follicular integrity as important factors in understanding disease mechanisms and potential therapeutic effectiveness.

In this phase I study, partial hair regrowth was observed in patients with alopecia universalis using topical JAK inhibitors, though more research is needed to confirm potential as a treatment alternative to clobetasol.

This article reviews treatment options and psychological impacts of alopecia areata and reports no new clinical findings.

Some people with primary cicatricial alopecia also have inflammatory bowel disease, suggesting a possible connection.

This review discusses various treatment options for Alopecia Areata, focusing on both medical and psychological approaches, and reports no new clinical results.

This review highlights recent advancements in understanding and treating alopecia, emphasizing genetic and immune factors involved in different forms, and discusses emerging therapies such as gene-editing and exosome-based treatments, though achieving complete hair regrowth remains a challenge.

This study found that genetic variants linked to hypothyroidism significantly increased the risk of developing alopecia areata, suggesting a causative connection between the two conditions.

This review summarizes recent advances in Treg cell biology, focusing on Foxp3's role in immune regulation and therapeutic reprogramming for immune dysregulatory disorders, but reports no new clinical results.

This review highlights recent insights into how IL-15 influences T cell responses and contributes to immunopathogenesis in various diseases, suggesting its crucial role in TCR-independent activation and potential in optimizing therapeutic strategies.

This study found that deleting Stim1 and Stim2 in mature T regulatory cells disrupts Ca 2+ signaling, preventing their differentiation and leading to severe autoimmune disorders in mice.

This study identified key genes and signaling pathways involved in the growth phases of Pashmina goat hair follicles, highlighting the role of several gene families and transcription factors in fiber quality and growth regulation.

This study, using multimodal profiling in mice, found that various tissues contain unique γδ T cell subsets adapted to their environment, revealing their functional diversity, lineage relationships, and similarities to CD8+ tissue-resident memory T cells.

This study found significant differences in gene expression between newborn and adult skin, with infant skin notably increasing processes related to ECM organization, cell adhesion, and collagen fibril organization.

In this study, researchers suggest that strategic early intervention during fetal wound healing could lead to significantly improved long-term skin regeneration outcomes.
