This review analyzes the wide range of extrapulmonary symptoms in COVID-19, highlighting variations in severity from mild cases with anosmia to severe cases impacting major organs.

This article reviews the nutritional needs and challenges for the elderly, emphasizing the benefits of antioxidants and healthy fats for immune support and overall health, but presents no new clinical results.

This study used single-cell RNA-sequencing data from mouse skin to reveal that fibroblasts show high transcriptional plasticity during wound healing, forming transient microniches early on and stratifying scar tissue into distinct molecular layers over time.

This review examines the roles of macrophages and fibroblastic cells in organ injury and repair, discussing their impact on outcomes ranging from regeneration to fibrosis, without presenting new clinical results.

This review discusses strategies to enhance mesenchymal stem cell therapy effectiveness but reports no new clinical results; it highlights the need for improved consistency and efficacy in MSC-based treatments.

This article describes how HIV-related skin disorders vary in presentation among pigmented skin types and highlights challenges in their diagnosis due to atypical disease manifestations.

In this study, researchers reported that the Pinkie mutation in mice, affecting RXRa activity, leads to skewed Th1 development and suggests RXRa's role in Th2 differentiation, impacting immune responses.

This research examined the transcriptional landscape of quiescent melanocyte stem cells (qMcSCs) in adult female mice, revealing significant heterogeneity within this cell population and identifying novel subpopulations that vary in immune privilege regulation, melanocyte differentiation potential, and neural crest potential.

This review discusses the association between various skin conditions and metabolic syndrome, reporting no new clinical results but suggesting a potential reciprocal relationship that warrants further investigation.

This study demonstrated that both classical and atypical BSE strains from cattle can be transmitted to goats, highlighting the importance of surveillance in protecting public health.

This study found that sebaceous gland-derived cutaneous adnexal carcinomas exhibited the highest frequency of genomic alterations compared to other tumor types.

This study found that pediatric alopecia areata patients with atopic predisposition showed heightened immune and inflammatory responses, including significant immune cell infiltration, compared to adults and healthy controls.

This study analyzed scalp hair proteins from healthy children and their mothers, finding that non-structural proteins could serve as promising biomarkers for understanding long-term developmental changes and health status linked to early childhood experiences.

In this chapter, researchers discuss how microRNAs (miRNAs) interact with vitamin D signaling, highlighting their emerging role as mediators in vitamin D-regulated disorders and their potential for developing miRNA-based clinical applications.

The document concludes that understanding health requires considering evolutionary perspectives on reproductive fitness, and recognizing the complexity of factors like diet, testosterone, and sexual orientation.

Langerhans cells are crucial for skin immunity and allergic reactions.

This article explores various skin reactions linked to COVID-19, including "COVID toes" and other rashes, which tend to appear in mild cases, while severe conditions like livedo reticularis are more often seen in critically ill patients, according to medical experts.

In this study, a new topical formulation containing amine-activated carboxymethyl chitosan and hydrolyzed extracellular matrix showed promising results in a mouse model by reducing oxidative stress, inflammation, and promoting hair regeneration, potentially offering an alternative treatment for inflammatory hair loss.

In this review, researchers explored how various cell types and molecular mechanisms contribute to wound-induced hair follicle neogenesis, highlighting its potential as a therapeutic approach for regenerating hair follicles and minimizing scar formation after injury.

This study found that mutant cells in hair follicles can be tolerated or eliminated by surrounding normal tissue, suggesting the potential for wild-type cells to counteract oncogenic mutations.

This report describes two cases where patients developed alopecia while undergoing treatment for psoriasis with IL-17 inhibitors, suggesting an unexpected paradoxical reaction.

This review discusses recent advances in hair follicle research, highlighting therapeutic and cosmetic applications, but reports no new study results.

The conclusion is that managing hair loss conditions like FFA and melanoma requires individualized approaches, considering new findings and balancing treatment benefits with potential risks.

This review highlights the promise of small extracellular vesicles (sEVs) as biomarkers for sepsis, emphasizing their potential to improve early detection and guide therapeutic decisions by reflecting the immune status and pathogen presence in patients.

This study found that DNA methylation and histone modification status were altered in peripheral blood mononuclear cells of patients with alopecia areata, suggesting these changes may contribute to the disease's pathological immune responses.

This study involving 81 yaks found significant correlations between melatonin, dihydrotestosterone, and immunoglobulin levels in blood serum and mineral content in hair, suggesting these factors may jointly influence yak hair growth and immune status, providing a potential non-invasive indicator of overall health.

This study observed that in Korean HIV patients, tinea infection, folliculitis, and seborrheic dermatitis were the most common skin diseases, with HAART medications generally reducing folliculitis incidence. Skin disease prevalence differed by immune status, affecting treatment needs.

This study analyzed blood samples from individuals with alopecia areata and found that NKG2D+ immune cells, particularly memory-like NK cells, may better correlate with disease activity compared to CD8+ cells, though significant variability among individuals complicates these findings.

This research found that topical minoxidil may promote hair regrowth in alopecia areata by stimulating hair follicle epithelium and suppressing certain immune responses, with potential contributions from its vasodilatory effects.

This review highlights the multifaceted roles of skin in immune and endocrine functions, stressing its contributions to psycho-immunological and psycho-endocrine responses, but presents no new research findings.
