This paper discusses two preclinical models for studying alopecia areata and finds that testing new therapeutic agents should involve both the C3H/HeJ mouse model and the humanized mouse model for comprehensive insights.

This review examines emerging and past therapies for recurrent implantation failure, focusing on three innovative strategies: PBMC, G-CSF, and PRP, but reports no new clinical results.

This review discusses the clinical phenotypes of primary mitochondrial cytopathies linked to significant genetic defects in mitochondrial DNA, reporting no new clinical results; the authors emphasize the need for differential diagnosis.

This study found that poly(butylene citramalate-co-butylene succinate) copolymers exhibit high toughness, recyclability, degradability, and biocompatibility, achieving complete wound healing with skin and hair follicle regeneration in 7 days.

Apremilast may help treat hair loss in alopecia areata.

In this study, researchers isolated new compounds from the plant *Calanthe cardioglossa* and found that five of these compounds, particularly calancardin B, significantly reduced TNF-α levels in immune cells relevant to multiple sclerosis, suggesting potential for immunomodulatory effects.

This study reported that bioactive peptides from skin collagen, obtained through selective hydrolysis, improve skin collagen synthesis and remodeling, while inhibiting its breakdown by metalloproteinases, showing benefits such as enhanced skin hydration, elasticity, healing, and hair restoration, without associated adverse effects.

This study found that activating Toll-like receptor 3 signaling in periodontal ligament stem cells may enhance their immunomodulatory properties, suggesting potential implications for future stem cell therapy applications.

This review reports that platelet-rich plasma may be more effective for musculoskeletal conditions when prepared with high platelet doses and low leukocyte content, but further trials are needed to confirm optimal formulations.

This study documented distinct expression patterns of stem cell markers LGR5 and LGR6 in various human skin tumors, highlighting differences in their potential roles and contributions to tumor development.

This report analyzed an FDA adverse event database and aimed to evaluate and describe post-finasteride syndrome potentially related to dutasteride, but it does not report new clinical findings.

This article reviews the potential of using PBM in 3D tissue engineering to improve cell viability under stress conditions but reports no new experimental findings.

This study found that patients with alopecia areata had higher levels of Th17 cells and lower levels of regulatory T cells compared to healthy controls, suggesting an immune imbalance in these patients.

In this study, researchers observed that dysregulated innate lymphoid cells type 1, alongside CD8+ T cells, may contribute to the pathogenesis of alopecia areata by affecting hair follicle health.

This case study describes a rare presentation of childhood lupus with recurrent pericardial effusion and cardiac tamponade that responded to glucocorticoid therapy.

In this study, researchers found that alopecia areata is linked to immune cell activation against hair follicle autoantigens and is associated with heart changes and cardiac marker alterations in humans and mice.

This review explores animal models of alopecia areata, particularly focusing on the insights they've provided into the disease's immune mechanisms and potential treatment approaches, without reporting new experimental data.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

This study observed that patients with recurrent furunculosis had different cytokine profiles compared to healthy subjects and that retinol stimulation altered cytokine secretion in both groups.

This study found that L-glutamine supplementation in Hanwoo steers under heat stress did not affect growth performance or muscle and adipose tissue gene expression but was associated with increased immune cells and reduced HSP90 expression.

This study found that the novel IPC analog SIG-1451 may inhibit inflammatory cytokine release in cell-based assays relevant to allergic dermatitis.

This study found that human hair follicle dermal papilla cells and keratinocytes self-assembled differently in 3D spheroid co-cultures, providing insights into cell distribution and organogenesis during skin regeneration.

In this study, researchers found that alopecia areata patients show a significant reduction in suppressive regulatory T-cells and an increase in inflammatory T-cell populations, suggesting an immunological imbalance contributing to the disease.

This study found that fisetin, a dietary flavonoid, significantly improved psoriasiform skin lesions in mice by promoting cell differentiation, inhibiting proliferation, and modulating inflammatory responses.

In this study, the novel isoprenylcysteine analog SIG-1451 was shown to inhibit pro-inflammatory cytokine release in various cell-based assays relevant to allergic dermatitis, acting on targets such as IL-4 and IL-6 with potential anti-inflammatory benefits.

This study found that retinoic acid and a retinol complex formulation showed different permeation and compound localization in a skin equivalent model, with unique lipid changes observed with only the retinol formulation.

Some treatments can improve skin's defense against damage, but overuse may cause other skin problems.

This study explores the correlation between sirtuins' expression, histone deacetylation, and redox status in young and old monozygotic twins to understand their role in age-related mechanisms.

This study found that Nrf2 activation protected keratinocytes from UVB damage but also caused thickening, inflammation, and cysts, limiting its therapeutic potential for skin protection.

In this study, estradiol was found to increase VEGF expression in cultured dermal papilla cells at physiological levels similar to pregnancy, suggesting that declining estrogen might contribute to female pattern hair loss in older Japanese women.
