This study describes the expression patterns of type I inner root sheath keratin proteins K25–K28 in human hair follicles, highlighting their distinct distribution within different layers.

This review discusses the potential of combining low-dose IL-2 with islet antigens to enhance antigen-specific Treg function in type 1 diabetes, but reports no new clinical results.

This study found that dexpanthenol treatment reduced inflammation, oxidative stress, and apoptosis in rats, providing a protective effect against lipopolysaccharide-induced cardiac and endothelial damage.

This article discusses the affordability and safety of platelet-rich plasma gel production but presents no new research findings.

In this study, researchers found that during late pregnancy, neuroactive steroid fluctuations increase the number of extrasynaptic GABAA receptors in rat hippocampal cells.

This study observed that hereditary factors were associated with acne duration but not severity, and found a potential role of CYP450 1A1 polymorphisms in acne pathogenesis.

This study identified key genetic regions associated with alopecia areata, highlighting both acquired and innate immune involvement, with a novel link to the upregulation of ULBP ligands in autoimmune disease.

This study found that JAK inhibitors promote hair regrowth in both mice and human alopecia areata cases by blocking key immune pathways involved in disease development.

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

This study found that human fetal CD133+ progenitor cells and their conditioned medium accelerated wound healing and promoted angiogenesis in a mouse model of ischemic diabetic ulcers through paracrine mechanisms involving Wnt signaling.

Understanding and targeting specific molecules can help reduce scarring and promote scar-free healing.

In this study, IL-6 expression in transgenic mice thickened the stratum corneum without causing increased epidermal proliferation or inflammation, suggesting it may enhance skin protection rather than directly induce inflammation.

This review discusses biological sex differences in COVID-19 outcomes and reports no new clinical results; it identifies a need for studies to clarify how sex influences disease progression.

In this research, authors found that skin-resident ILCs regulate sebaceous gland function and microbial balance, emphasizing an immune-epithelia system that supports host-microbe symbiosis.

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.

The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.

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 study found that pro-inflammatory cytokines and apoptotic mechanisms, specifically involving granzyme B and Fas pathways, are associated with chronic alopecia areata, indicating their potential role in the disease's persistence.

This review summarizes recent advances in Treg cell biology, focusing on Foxp3's role in immune regulation and therapeutic reprogramming for immune dysregulatory disorders, but reports no new clinical results.

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 study observed that patients receiving IL-2 immunotherapy developed a skin eruption characterized by burning and pruritus, which resolved shortly after stopping the infusion, suggesting that IL-2 mediated these effects.

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 article offers a viewpoint on hidradenitis suppurativa pathogenesis, suggesting that impaired Notch signalling from γ-secretase mutations may drive inflammation and link the condition to other Th17-driven diseases.

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 study found that interleukin-1 directly induces the expression of keratin 6 in keratinocytes, which is a marker of activation and involved in inflammatory skin responses.

In this study, oral administration of Lactococcus lactis strain H61 to senescence-accelerated mice was linked to reduced bone density loss, less skin ulcer incidence, and reduced hair loss, along with altered immune responses.

In this study, AS101 combined with chemotherapy significantly reduced the severity of chemotherapy-induced alopecia in non-small-cell-lung-cancer patients and may involve immune mechanisms related to IL-1 and PGE2.

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 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 highlights the evolving understanding of acne's pathophysiology and suggests that targeting pro-inflammatory cytokines such as IL-1β, IL-17, IL-23, and TNFα with biological antibodies may offer new treatment strategies for severe acne and its scars.
