This study found that dupilumab treatment in alopecia areata significantly suppressed Th2-related markers and increased hair keratin levels, suggesting a potential role of Th2 cytokines in the disease's pathogenesis.

This study suggests that frontal fibrosing alopecia is a highly inflammatory disease involving TH1 and JAK-STAT pathways, without reduced hair keratins, highlighting JAK-STAT signaling as a potential therapeutic target.

In this retrospective study, researchers found a statistically significant increase in the risk of alopecia areata among atopic dermatitis patients using dupilumab compared to controls, suggesting the need for careful monitoring and further research on the drug's impact on alopecia areata.

This review found that autoimmune damage is a key factor in alopecia areata, noting its comorbidity with other diseases and the potential of Janus kinase inhibitors in treatment.

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.

In this study, IFN-γ-stimulated iPSC-derived mesenchymal stem cell extracellular vesicles improved atopic dermatitis in mice by reducing Th2 cytokine activity, suppressing inflammation, and restoring skin barrier function, as evidenced by decreased itching and inflammatory markers.

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 found that a specific mutation in the mouse RXRalpha gene significantly impacts immune responses and causes hair loss and skin cysts.

This study found that selective deletion of Ctip2 in epidermal keratinocytes in adult mice leads to atopic dermatitis-like inflammation and suggests Ctip2 plays a crucial role in skin barrier maintenance and inflammatory regulation.

In this study, researchers developed a dissolvable microneedle patch combining HA-TEMPO and Portulaca oleracea L.-derived nanoparticles, which effectively reduced oxidative stress and inflammation in an atopic dermatitis model while restoring immune balance, suggesting a promising treatment strategy.

This review discusses the role of tumor suppressors in controlling tumor-associated inflammation and suggests that targeting this inflammation may counteract the effects of tumor suppressor loss.

This review discusses the features of regulatory T cells and the modulation of Foxp3, emphasizing post-translational modifications' impact on Treg function but reports no new clinical results.

In this study, CD4+CD25+FoxP3+ Regulatory T cells were found to reduce TGF-b1 induced lung fibrosis and fibrocyte accumulation in mice, partly by suppressing fibroblast growth factor 9.

This review discusses the evolution of alopecia areata treatments towards more targeted therapies and reports no new clinical results, emphasizing cooperation between clinicians and scientists in understanding the disease's pathophysiology.

This study found that dupilumab's effects on alopecia areata varied depending on patients' immune profiles, with Th2-skewed females seeing improvements and Th1-driven males experiencing worsening.

This study found that reduced expression of CD200R1 on monocyte-derived macrophages in rheumatoid arthritis patients was significantly associated with higher disease severity and an imbalance in Th17/Treg cells.

In this study, Treg depletion impaired skin wound healing in mice, potentially by altering the cytokine environment and expanding certain T-cell populations, disrupting the normal healing process.

This study found that a quinazoline derivative, SH-340, increased skin barrier-associated factors and inhibited TSLP expression and STAT6 phosphorylation in human primary keratinocytes, suggesting potential benefits for alleviating inflammation and improving skin barrier function in atopic dermatitis.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.
