This report describes a case of alopecia universalis successfully treated with tofacitinib, though it was associated with increased peripheral blood cytokine levels.

This review discusses the potential of ginseng and its metabolites for treating hair loss and reports no new clinical findings.

In this study, researchers found that changes in immune cell infiltration and immune-related gene expression may contribute to the immune microenvironment changes in male androgenetic alopecia.

JAK inhibitors show promise for treating alopecia areata, but more research is needed.

This review discusses human sebocyte in vitro models for studying sebaceous gland function and control but reports no new clinical results, highlighting hormonal effects and the impact of retinoids on sebocyte activity.

IL-6 contributes to hair loss by shortening the growth phase and causing hair follicles to regress.

Alopecia areata is an autoimmune disorder causing hair loss, linked to specific hair follicle antigens and genetic factors.

This review discusses recent advancements in scar reduction techniques, highlighting promising therapeutic targets and the role of Wnt/β-catenin signaling in promoting scarless wound healing, but reports no new clinical results.

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 study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This review compares various rodent models that reflect aspects of psoriasis with human psoriasis and potential applications for research, reporting no new clinical findings.

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 meta-analysis estimated that around 80% of patients who had COVID-19 experienced at least one long-term symptom, with fatigue being the most common reported effect.

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 study concluded that cytokines and growth factors significantly regulate hair growth in vitro, with some completely inhibiting growth, such as EGF and TNFα.

This review discusses androgenetic alopecia and alopecia areata through a systems biology lens, emphasizing the role of multi-omics data integration to explore molecular mechanisms and potential therapeutic strategies, but offers no new clinical results.

This study suggests that Notch1 acts as a key signal in skin epithelium, promoting immune cell recruitment and aiding in normal skin repair after damage.

This study found that administering melatonin for 12 weeks to women with PCOS significantly reduced hirsutism, testosterone, and inflammation markers, while enhancing antioxidant levels compared to a placebo.

This study reviewed the use of dupilumab, beyond its approved indications for atopic dermatitis and prurigo nodularis, and found effective treatment reports for various chronic inflammatory skin diseases such as bullous autoimmune diseases, eczema, and alopecia areata, highlighting its broad potential in dermatology.

This study found that local injections of interleukin-4 and neutralizing anti-interferon-γ antibody effectively treated alopecia in a mouse model, suggesting potential therapeutic pathways for human alopecia areata.

This study found that CD45RO+ cells, a subtype of T lymphocytes, were notably reduced in the ovarian follicles of women with PCOS, which may contribute to the condition's pathogenesis.

This article reviews the role of perifollicular regulatory T cells in maintaining hair follicle integrity in the context of hidradenitis suppurativa and calls attention to inflammatory mechanisms without reporting new clinical results.

This review discusses recent advances in how proinflammatory cytokines affect epidermal stem cell function during skin wound healing and introduces potential therapies targeting these cells and cytokines.

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.

This review discusses the neurobiology and proposed mechanisms of scalp itch, but it does not report new clinical findings, highlighting the need for further research in this area.

This paper discusses the variability in COVID-19 susceptibility and severity, emphasizing factors like biological differences and suggesting potential precision medicine approaches, but it reports no new clinical results.

Alopecia areata severity is linked to increased TH1 and TH2 activity.

This study found that 17β-estradiol inhibited RANTES production in human keratinocytes by suppressing nuclear factor κB activity, suggesting a potential mechanism for 17β-estradiol's modulation of psoriasis-related inflammation.

This research explores developing liposomal formulations to enhance the delivery of difficult-to-absorb agents directly to hair follicles and sebaceous glands, with minoxidil and plasmid DNA as study molecules.

This study found that Imuvert consistently protected against alopecia induced by certain chemotherapy drugs in rats, potentially mediated by a monocyte-derived cytokine like interleukin-1.
