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

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 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 the oral JAK1/JAK2 inhibitor deuruxolitinib effectively promoted hair regrowth and patient satisfaction in adults with alopecia areata over 24 weeks.

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 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.

This article reviews the regulation of androgens in human skin and adrenals, highlighting their role in skin disorders, but reports no new research findings.

This study found that intron 3 VNTR polymorphism in the IL-4 gene may be associated with an increased risk of alopecia areata in the Turkish population.

This review discusses current and potential treatments for alopecia areata, focusing on immunosuppressive and immunomodulatory approaches, but provides no new clinical results.

This study found that IL-25-mediated-IL-17RB signaling improved diabetic wound healing by enhancing angiogenesis, collagen deposition, and endothelial cell function, suggesting a potential therapeutic strategy for poorly healing diabetic wounds.

SACUMAN, a rare condition causing hair loss without clear signs, is often misdiagnosed and needs scalp biopsies for accurate detection.

This study investigated the role of NLRP3 inflammasomes in alopecia areata and found that outer root sheath cells may contribute to inflammation by increasing IL-1β and HMGB1 secretion when stimulated with double-stranded RNA.

In this study, researchers found that specific IL18 genetic variants may be linked to increased susceptibility to alopecia areata in a Korean population.

This study found increased IL-18 levels in the endometrium of women with polycystic ovary syndrome, especially in those who are overweight, suggesting a link with body mass index.

This study found that UV-B exposure significantly increased the expression of inflammatory cytokines IL-1β and IL-8 in cultured sebocytes.

This article reviews adverse skin reactions caused by chemotherapy and cytokine treatments, describing specific and nonspecific reactions, but reports no new clinical findings.

This study found that acellular dermal matrix scaffolds may facilitate full-thickness skin wound healing by promoting a pro-regenerative immune response through M2 macrophage polarization via the Lamtor1 pathway.

In this study, minoxidil significantly downregulated interleukin-1 alpha expression in human keratinocyte cells, suggesting an anti-inflammatory effect that may be a mechanism of action in treating alopecia.

This study found that alopecia areata patients had higher baseline interleukin levels, which significantly decreased with tofacitinib treatment, though this change did not correspond to disease severity improvement.

This review examines treatments for chemotherapy-induced alopecia, reporting that combining mechanical and chemical interventions may offer some benefits, though the evidence is not yet definitive.

This study found that isolated red light may serve as an alternative for photo-immunotherapy without additional photosensitizers, as it did not reduce keratinocyte differentiation markers or increase photo-oxidative damage, unlike treatment with IL-4 or UVA1/blue light.

This review discusses gene polymorphisms in COVID-19 patients but reports no new clinical findings.

This study found that IL-1α promotes hair follicle regeneration and stem cell activation in an age-dependent manner by modulating inflammatory cells and oxidative stress in mice.

This study found that recombinant murine IL-36α increased the number of regenerated hair follicles and accelerated wound healing in a mouse model of wound-induced hair follicle neogenesis.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

Tocilizumab treatment was associated with significant hair regrowth in one patient and temporary hair loss followed by regrowth in another.

This study found that etifoxine pretreatment reduced neuroinflammation and improved cognitive function in LPS-induced neuroinflammation in mice, potentially through increased neurosteroid synthesis and reduced apoptosis.

This analysis examines acne vulgaris using an integrative approach, highlighting its links with psychopathology, lifestyle, and diet, but reports no new results.
