This study observed that PD-1+CXCR5-CD4+T peripheral helper cells are significantly elevated in patients with systemic lupus erythematosus and are correlated with disease activity indicators, suggesting their potential role in lupus pathogenesis.

This study found that tenofovir alafenamide fumarate (TAF) is an effective and safer alternative to tenofovir disoproxil fumarate (TDF) for chronic hepatitis B, with fewer long-term side effects like nephrotoxicity and decreased bone density.

This article discusses the potential of oral tofacitinib as a treatment for atopic dermatitis, alopecia areata, and vitiligo, without presenting new clinical results.

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 study reports that CD200R expression is significantly reduced in a mouse model of scarring alopecia, suggesting a potential role for this pathway in immune regulation and hair follicle protection.

This study found that alefacept showed no significant improvement in treating severe alopecia areata compared to placebo over a 24-week period.

This article reviews the autoimmune mechanism and potential environmental triggers of alopecia areata, focusing on cytokines, but does not provide new research findings.

This study found that both Th1 and Th2 cytokine markers were elevated in the serum and skin of patients with alopecia areata, with Th2 markers more closely linked to disease severity.

This study found that in individuals with alopecia areata, intralesional Triamcinolone therapy led to significantly greater reduction in disease severity, measured by SALT scores, compared to autologous platelet-rich plasma treatment over a 24-week period.

In this study, treatment with flutamide combined with a low-dose oral contraceptive significantly improved hirsutism in women with polycystic ovarian disease who did not respond to oral contraceptive treatment alone.

This case report describes a 29-year-old woman with longstanding alopecia areata who experienced improvement in her scalp hair loss after 7 years of topical treatment with squaric acid dibutylester.

This case report describes a 22-month-old with alopecia universalis who showed improved hair growth after receiving combination therapy with minoxidil, corticosteroids, and excimer laser.

The trial is ongoing, but researchers are evaluating the efficacy and safety of REZPEG, a potential new therapy for severe alopecia areata, which selectively expands regulatory T cells.

This study found that androgenetic alopecia in men is associated with significant psychological distress and moderate depression, suggesting a possible link between raised dihydrotestosterone levels and mental health issues.

Significant hair regrowth doesn't always mean complete hair recovery in alopecia areata.

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.

Surgery for high-risk prostate cancer is challenging but doesn't lead to more complications, and additional treatment is often needed.

Using 5α-reductase inhibitors for hair loss in women doesn't increase cancer risk.

In this clinical trial, patients with lichen planopilaris treated with the oral TYK2 inhibitor deucravacitinib showed significant improvement in PGA, LPPAI, and Skindex-16 scores over 24 weeks, with transcriptomic analyses indicating decreased inflammatory and immune pathway activity post-treatment.

This review highlights the possible role of T regulatory cells in the immune-related mechanisms of alopecia areata but reports no new clinical findings.

This study found that inhibiting the PI3Kδ enzyme in murine models of cutaneous chronic graft-versus-host disease (cGVHD) reduced skin scores and fibrosis, prevented pathogenic lymphoid structures, and improved survival, suggesting it as a promising therapeutic approach to address the disease's hypoxic pathophysiology.

This study found that platelet-rich plasma had limited efficacy in treating alopecia areata but may help restore immune balance in the affected areas.

This study found that Th22 cells and their cytokine IL-22 may play an important role in the pathogenesis of systemic lupus erythematosus and could serve as bioindicators for monitoring disease severity.

In this study, patients with alopecia areata were found to have higher high-sensitivity cardiac troponin T levels compared to healthy controls, indicating a potential link between the condition and cardiovascular risk.

In this study, rheumatoid arthritis patients showed no changes in the number of circulating follicular helper T cells, but these cells had increased CD200 expression, implicating them in disease pathogenesis and suggesting CD200/CD200R as a potential therapeutic target.

This study observed that flutamide treatment reduced hair growth and improved acne and seborrhea in hirsute women, with increased androstenedione levels and no side effects noted.

This study observed that both ritlecitinib and brepocitinib improved scalp biomarkers in patients with alopecia areata, with associations to hair regrowth seen in this phase 2a trial.

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.

This study found that AiQingHua oil improved microcirculation and promoted hair regeneration in mice with testosterone-induced alopecia.

This study observed that oral tofacitinib was effective and safe for treating alopecia areata in paediatric patients, with 82% of pre-adolescent participants experiencing hair regrowth and 64% showing significant improvement in their hair loss severity scores.
