In this study, three patients with extensive alopecia areata showed varying degrees of hair regrowth after 20 weeks of treatment with ustekinumab, a cytokine-targeting therapy.

This report discusses two patients with plaque psoriasis who developed hypertrichosis, or excessive hair growth, while undergoing interleukin-17A inhibitor therapy.

This study found that type 2 immunity may play a role in the development of alopecia areata in patients with extrinsic atopic dermatitis, indicating different immunological states compared to non-atopic patients.

In this study, ustekinumab did not promote hair regrowth in human patients with alopecia areata or prevent disease development in an AA mouse model, suggesting limited efficacy for this treatment.

In this study, nearly 5% of anti-TNF-treated patients with IBD developed psoriasiform skin lesions, with smoking identified as a main risk factor, and ustekinumab proved highly effective in severe cases.

This study found that tannic acid accelerated wound healing in rats by modulating inflammatory cytokines, increasing growth factors, and activating the Erk 1/2 pathway.

This study found that compounds isolated from Osmanthus fragrans var. aurantiacus demonstrated antioxidative and anti-inflammatory activities, potentially offering therapeutic benefits for inflammatory bowel diseases by inhibiting COX-2 and iNOS enzymes and blocking ERK 1/2 MAPK signaling.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

This study found that ruxolitinib modulated inflammatory changes and stimulated growth factor signals by blocking the JAK-STAT pathway in an in vitro model of alopecia areata.

This research suggests that innate lymphoid cells type 1 (ILC1) may contribute to the development of alopecia areata, alongside CD8+ T cells, by disrupting hair follicle immune privilege and promoting features of the disease.

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 IL-1 blockers are effective for SURF and identified predictors of colchicine resistance, emphasizing the need for refined diagnostic criteria and personalized treatment due to the heterogeneity observed within SURF.

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 study found that procyanidins effectively alleviate neuropathic pain in mice by significantly inhibiting MMP-9/2 activity.

This study found that EGFR inhibitors and ligands did not significantly affect the expression of inflammatory biomarkers in cultured sebocytes, except for a notable increase in IL-1 expression with EGF treatment.

In this animal study, AGO (agomelatine) effectively alleviated testosterone-induced benign prostatic hyperplasia in rats by reducing oxidative stress and inflammation, indicating its potential as a therapeutic option for managing BPH through specific signaling pathways.

This study found that IL-7 is crucial for the survival of memory regulatory T cells in the skin of mice, whereas IL-2 is essential for their initial generation but not for their maintenance.

This study found that disrupting inflammasome signaling by eliminating caspase-1 and -11 in mice reduced skin inflammation and delayed the onset of disease, highlighting their role in skin disease pathogenesis.

This study investigated dermal fibroblasts in mouse skin using single-cell RNA sequencing and identified signaling pathways that influence adipogenesis, finding that IL-1-NF-κB promotes, while WNT-β-catenin inhibits, the adipogenic potential of these cells, with implications for wound healing and scar formation.

IL-1 receptor absence in mice leads to skin cysts and changes in immune response after UVB exposure.

This study found that UV exposure in human skin induces IL-10 production by macrophages, while Langerhans cells are depleted and their IL-12 production is downregulated.

This review summarizes recent research on alopecia areata, highlighting advances in targeted therapies due to improved understanding of its immunopathogenesis, though it reports no new clinical results.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

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.

This study reviews the efficacy and safety of advanced therapies like TNFα inhibitors and IL-17/IL-23 inhibitors for dissecting cellulitis of the scalp, finding TNFα inhibitors particularly effective for severe or refractory cases, although prospective validation is needed for early intervention benefits.

This chapter reviews studies on the side effects of cytostatics and immunosuppressive drugs, detailing various toxicities such as cardiovascular, pulmonary, and neurotoxicity, but provides no new clinical results.

In this study, rice bran mineral extract increased expression of anagen-related proteins and decreased inflammatory markers in human dermal papilla cells, suggesting potential for hair growth enhancement and prevention of hair loss.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This review discusses different types of alopecia associated with psoriasis and highlights that hair loss in psoriasis is typically non-scarring and reversible, while also noting the increased risk of alopecia areata in these patients.
