This review discusses how menopause and hormone replacement therapy affect skin aging in women but reports no new clinical findings.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This study introduces a novel chitosan-based hydrogel containing cinnamaldehyde-tannic acid-zinc acetate nanospheres, which reportedly enhances wound healing by promoting antibacterial, antioxidant, and anti-inflammatory effects.

In this study, researchers observed elevated levels of epidermal γδ T cells, keratinocytes, and an upregulation of the BST2 gene among immune cells in C3H/HeJ mice with alopecia areata, suggesting a potential role in disease pathogenesis.

This study demonstrated a novel use of tape stripping on a human skin model to simulate the inflammation and barrier damage caused by dry razor shaving, highlighting potential shaving and skin-care formulations that may mitigate such damage.

Langerhans cells are crucial for skin immunity and allergic reactions.

This case report describes how a 21-year-old male with alopecia areata and seborrheic dermatitis showed clinical improvements and symptom relief following a tailored, three-month functional nutrition protocol, highlighting potential benefits of addressing root causes in immune-related skin conditions.

This review explores the potential of multifunctional bioscaffolds in skin tissue engineering, highlighting their successful biological performance in vitro and in vivo animal models, while also identifying the demand for technological advancements to improve wound healing applications in clinical settings.

This study found significant differences in gene expression between newborn and adult skin, with infant skin notably increasing processes related to ECM organization, cell adhesion, and collagen fibril organization.

This study investigated the molecular mechanisms behind cashmere goat coat types by analyzing gene expression during hair follicle development stages, identifying regulatory pathways involved in metabolism, immune response, and the quiescent state of follicles, potentially aiding in genetic selection for improved cashmere production.

This review discusses how ionizing radiation causes skin damage by inducing cellular senescence in keratinocytes, which secrete inflammatory mediators, recruiting immune cells and exacerbating inflammation, impacting the skin barrier function and healing.

In this study, mouse models with EGFR deficiency showed that disrupted hair follicle cycling leads to increased mast cell numbers and inflammation, suggesting EGFR's role in managing hair cycle transitions and preventing folliculitis.

This review discusses the interactions between immune cells and the skin epithelium and their impact on maintaining barrier function, emphasizing the potential to enhance epithelial barrier function in inflammatory diseases.

This review highlights that the epidermis acts as an endocrine organ, synthesizing and responding to hormones such as corticosteroids and Vitamin D, impacting processes like hair growth and immune response, and participating in regulating endocrine balance.

This review discusses the dynamic, niche-driven regulation of stem cell states in tissue homeostasis and regeneration, focusing on epithelial stem cells in the mammalian skin, intestine, and lung, without providing new experimental results.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This article reviews the impact of psychological factors on skin health and discusses the interplay between stress, the brain, and the immune system but presents no new clinical findings.

This study explores the potential of adaptogenic herbal extracts like ashwagandha, rhodiola, and schisandra in treating stress-induced dermatoses, noting their effects on modulating the HPA axis, reducing inflammation, and improving skin barrier function.

This study found that mesenchymal stem cell treatment alleviated atopic dermatitis-like symptoms in a mouse model by modulating immune and inflammatory responses, with gene expression changes suggesting pathways for potential personalized treatment approaches.

This study found that Wnt secretion is important for maintaining skin homeostasis in mice, as Evi-deficient mice developed psoriasis-like skin lesions and had an imbalance in immune cell populations.

This review discusses the potential role of extracellular vesicles in modulating hair follicle dynamics and reports no new clinical results; future investigations may inform treatment strategies for skin disorders.

In this study, researchers analyzed spaceflight data from various sources and found that skin issues during spaceflight are linked to DNA damage, mitochondrial dysregulation, and gene alterations, while also highlighting the skin's adaptability post-flight.

This study found that Wnt secretion is important for skin homeostasis in mice, as Evi-deficient mice developed skin lesions resembling psoriasis and showed immune cell imbalance.

In this case report, a 7-month-old boy with Netherton syndrome experienced significant improvement in symptoms, including reduced pruritus and increased hair growth, through a combination of intravenous immunoglobulin and dupilumab treatment, which also decreased high serum IgE levels and food-specific IgE antibodies.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

This article reviews topical agents for cosmetic surgery and reports no new clinical results; it emphasizes the importance of skin preparation and management for optimal surgical outcomes.

Modifying gut bacteria with pro- and postbiotics may help treat hair loss.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This article discusses a novel hypothesis on the role of hair follicles in dandruff pathogenesis, focusing on immune response and inflammation due to scalp microbiota changes and sebum by-products, but reports no new clinical results.

This abstract highlights the potential applications of exosomes in dermatology, including scar treatment and hair regeneration, but notes that further clinical studies are needed to confirm their safety and efficacy and address regulatory challenges.
