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 IL-17/IL-36 signaling to be predominant in both endotypes of Netherton syndrome, with distinct molecular profiles between NS-ILC and NS-SE lesions, offering potential therapeutic targets.

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 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.

This study reports that tofacitinib, a JAK inhibitor, may stabilize hair loss in patients with classic lichen planopilaris and frontal fibrosing alopecia, though hair regrowth was not robust.

This study reviewed 18 studies on the effects of ustekinumab and vedolizumab on alopecia in ulcerative colitis patients, finding varied outcomes ranging from significant hair regrowth to increased hair loss, with 65.5% experiencing regrowth and potential therapy benefits needing further exploration in larger trials.

This study found that kaempferol increased the proliferation potential of basal epidermal cells in three-dimensional skin models by enhancing integrin expression and altering cell morphology.

This study found that elevated STAT5 levels are linked to improved hair-inducing capabilities in human dermal papilla cells, and reducing STAT5 impairs hair follicle induction.

This study found that treating human dermal fibroblast cells with ginsenoside Rd increased the expression of mRNA associated with the dermal-epidermal junction, suggesting potential as an anti-aging cosmetic ingredient.

This study found that TGFbeta is a key pathway causing age-related loss of dermal fat's antimicrobial function, suggesting that targeting TGFBR might help restore skin defense against infections in older age.

This study found that the absence of Hes1 in hair follicles delays secondary hair germ activation and shortens the anagen phase, impacting HFSC self-renewal and long-term hair regeneration.

This study found that ethanol extract of Tubtim Chumphae rice bran downregulates SRD5A gene expression, similarly to finasteride, suggesting potential use as an anti-hair loss product.

This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

This review examines the impact of vitamin D signaling in extraskeletal tissues and notes that expected benefits from animal and cell studies have not been consistently replicated in human clinical trials.

This review examines the neuroendocrine mechanisms underlying seasonal changes in mammals and highlights areas needing further research, reporting no new experimental results.

This review discusses recent advances and ongoing clinical trials in novel therapeutics for alopecia areata, despite the lack of current FDA-approved treatments for severe cases, and reports no new results.

Apremilast was not effective in treating moderate-to-severe alopecia areata.

This study found that Israeli patients with alopecia areata had a higher prevalence of comorbid conditions, including food allergies and chronic spontaneous urticaria, compared to matched controls.

This study found that administering spermidine to aged mice for six months significantly reduced various age-related conditions, including brain, heart, kidney, liver issues, and hair loss, possibly due to decreased telomere attrition.

This review examines recent findings on COVID-19 pneumonia treatment using mesenchymal stem cells and reports no new clinical results; the authors highlight MSCs' potential due to their immunomodulatory and tissue-regenerative properties.

This study found an association between atopic dermatitis and autoimmune diseases in both adults and children, with women more likely to experience these complications, but further research is needed due to limited participant numbers.

Pumpkin seeds may help expel parasites, but findings are retracted.

In this narrative review, researchers outlined the role of T cells in the autoimmune pathogenesis of alopecia areata and highlighted ongoing research into therapeutic pathways, beyond current JAK inhibitors, aimed at developing new treatments for the disease.

This study found that CD2 could be a potential new therapeutic target for treating patchy-type alopecia areata, suggesting the need for further research into its role.

This review discusses the impaired functionality of regulatory T cells in the pancreas during the development of Type 1 diabetes, highlighting their role in disease pathogenesis, potential of Treg-based therapies, and challenges in clinical applications.

This study found that PPARα agonists provided protective effects in mouse models of alopecia areata by promoting early reversal of the condition and inhibiting T effector cell function, indicating potential therapeutic value for this inflammatory condition.

This chapter discusses the composition, biocompatibility, and production methods of biomaterials like collagen, chitin, and silk for dermal substitutes, focusing on preclinical and clinical research, but reports no new clinical results.

In this study analyzing FDA data, researchers found that tralokinumab was associated with higher reports of conjunctivitis and keratitis compared to dupilumab, while dupilumab had more frequent injection site reactions, highlighting potential risks for clinical monitoring in atopic dermatitis treatments.

This review identified evidence gaps in NHIRD, emphasizing the lack of validated diagnostic criteria and the need for further research on ocular and systemic comorbidities associated with AA to enhance patient care and treatment strategies.

In this study using mouse models, researchers found that elevated IL-17a in aged olfactory epithelium impairs olfactory function, while IL-17a inhibition promotes regeneration and mitigates age-related decline.
