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 review discusses common skin eruptions caused by biologics in treating inflammatory bowel disease and proposes tailored therapeutic approaches for managing these adverse reactions.

This research found that reduced expression of SIRT1 in human scalp tissue may contribute to alopecia areata development by inducing immune-inflammatory responses in hair follicle cells, suggesting that SIRT1 plays a regulatory role in hair follicle immunity.

This study found that intracellular Toll-like receptors were significantly up-regulated in peripheral blood mononuclear cells of alopecia areata patients, suggesting a potential role in inflammatory signaling and pathogenesis.

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 abstract provides no new clinical results; it discusses the role of surgery and interventional radiotherapy in treating cutaneous squamous cell carcinoma.

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 case report describes a patient with Crohn's disease developing alopecia and psoriasiform skin lesions while on adalimumab treatment.

This study used digital-light-processing bioprinting to create a 3D skin-on-a-chip model with a miniaturized vascular network to closely study immune cell interactions similar to real human skin, demonstrating the potential to analyze immune-T cell trafficking influenced by skin signals.

This review discusses various potential treatments for alopecia areata, highlighting the promise of Janus kinase inhibitors but reports no new clinical results.

This study suggests that STAT3 signaling in keratinocytes is crucial for maintaining skin homeostasis by regulating hair follicle-specific keratin genes, potentially impacting dermatitis development through microbe-triggered inflammatory responses.

This review discusses the complexities of hidradenitis suppurativa pathogenesis, highlighting issues with Notch signaling, immune dysregulation, and the role of keratinocytes and ECM, but reports no new clinical results.

This study found that oral JAK3 and TYK2/JAK1 inhibitors improved clinical outcomes in alopecia areata patients by reducing immune responses and enhancing hair keratin expression, with stronger effects in those with shorter disease duration.

This study found that hidradenitis suppurativa is associated with increased serum levels of hypoxia-inducible factor-1α, suggesting its role in the disease's pathogenesis and as a treatment target.

This review discusses the shared biological mechanisms between allergy and autoimmunity, emphasizing pruritus as a central symptom in psychophysiological dermatoses, and reports no new clinical results.

This study suggests that IL-4 and IL-13 may play a role in the immunopathogenesis of alopecia areata in some patients, indicating a possible Th2-driven pathway in this condition.

This study found that the Yangyin Qingre Huoxue Prescription effectively reduced the progression of atherosclerosis in mice, with lipid-regulating and anti-inflammatory functions and lower hepatotoxicity than simvastatin.

This review of seborrheic dermatitis highlights the role of complex immunoinflammatory processes in its pathogenesis and discusses emerging treatments, such as PDE4 inhibitors, JAK inhibitors, and microbiome-targeted therapies, which may benefit patients with severe or treatment-resistant forms, according to the authors.

This review discusses the complex role of immune disturbances and the JAK-STAT pathway in alopecia areata, noting the success of JAK inhibitors in treatment, while highlighting ongoing debates and challenges in targeting other pathways like IL-17 and TNF-α.

This research discusses the complex immune pathogenesis of alopecia areata and highlights the success of Jak inhibitors and IL-4Rα antagonists, while IL-17A and PDE4 inhibitors showed limited efficacy; controlled trials are advocated to better understand cytokine involvement.

This review of 32 articles suggests a stronger association between alopecia areata and allergic rhinitis than asthma in both adults and children, indicating a potential Th2-mediated component.

This mouse study found that offspring of parents with uveitis showed increased susceptibility to experimental autoimmune uveitis, potentially due to altered immune and cellular processes.

In this study, researchers reported that the Pinkie mutation in mice, affecting RXRa activity, leads to skewed Th1 development and suggests RXRa's role in Th2 differentiation, impacting immune responses.

This study found that in a mouse model of psoriasis, depleting CD169⁺ macrophages led to milder symptoms and decreased inflammation, suggesting these macrophages play a crucial role in psoriasis development.

This study found that alopecia areata is associated with distinct systemic and tissue immune signatures, with macrophages implicated as contributors to hair loss, suggesting potential therapeutic targeting of macrophage activity.

This review highlights that T cells are crucial in regulating hair follicle regeneration and their disruption can lead to alopecia, providing insights into hair disorders related to T cell immune balance and hair follicle regeneration.

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 study reviewed the expression of chemokines in patients with alopecia areata, finding elevated Th1 and Th2 chemokine levels, suggesting a complex immune profile that may require broad immunomodulatory strategies to address the disease's underlying immune dysregulation.

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.
