Article Abstract

Fungi increasingly threaten health globally. Mycoses range from life-threatening, often iatrogenic conditions, to enigmatic syndromes occurring without apparent immunosuppression. Despite some recent advances in antifungal drug development, complementary therapeutic strategies are essential for addressing these opportunistic pathogens. One promising avenue is leveraging host immunity to combat fungal infections; this necessitates deeper understanding of the molecular immunology of human fungal susceptibility to differentiate beneficial versus harmful immunopathological responses. Investigating human models of fungal diseases in natural settings, particularly through genetic immunodeficiencies and ethnographic-specific genetic vulnerabilities, reveals crucial immune pathways essential for fighting various yeasts and molds. This review highlights the diversity in intrinsic fungal susceptibility across individuals and populations, through genetic- and autoantibody-mediated processes, complementing previous principles learned from animal studies and iatrogenic contexts. Improved understanding of human immunity to fungal diseases will facilitate the development of host-directed immunotherapies and targeted public health interventions, paving the way for precision medicine in fungal disease management.

Introduction: Despite high coverage of routine childhood vaccines, uptake of the human papillomavirus (HPV) vaccine in the Pacific Island nation of Tonga has been slow. Culturally appropriate communication resources on the importance, safety, and effectiveness of the HPV vaccine are critical to support acceptance and uptake. To develop these resources, it is important to understand what people want to know.

Purpose: We reviewed recent advancements in the characterization of intraductal oncocytic papillary neoplasm (IOPN) of the pancreas, with a specific focus on developments in immunohistochemical markers, molecular pathology, and pathogenic mechanisms over the past ten years (2015-2024). Through comprehensive analysis of current literature, we aimed to elucidate the evolving understanding of IOPN's biological behavior and diagnostic features, while identifying potential areas for future research in this distinctive pancreatic neoplasm.

Methods: English-language articles on IOPN were searched from Pubmed from the first report of IOPN of the pancreas in 2015 to 2024.

Label-free immunoassay based on chemiluminescence-functionalized magnetic mesoporous nanoparticles for rapid detection of neuron-specific enolase.

Lung cancer, as one of the cancers with the highest morbidity and mortality rates in the world, requires accurate detection of its vital serum marker, neuron-specific enolase (NSE), which is a key challenge for early detection of lung cancer. However, traditional chemiluminescence immunoassay (CLIA) methods rely on labeled antibodies (Abs) and suffer from complex operations and high costs. In this work, a label-free CLIA based on CL-functionalized mesoporous magnetic nanoparticles (CuFeO@mSiO-Cys-Luminol-Au NPs) is developed for the rapid and sensitive detection of NSE.

It has become evident from decades of clinical trials that multimodal therapeutic approaches with focus on cell intrinsic and microenvironmental cues are needed to improve understanding and treat the rare, inoperable, and ultimately fatal diffuse intrinsic pontine glioma (DIPG), now categorized as a diffuse midline glioma. In this study we report the development and characterization of an in vitro system utilizing 3D Tumor Tissue Analogs (TTA), designed to replicate the intricate DIPG microenvironment. The innate ability of fluorescently labeled human brain endothelial cells, microglia, and patient-derived DIPG cell lines to self-assemble has been exploited to generate multicellular 3D TTAs that mimic tissue-like microstructures, enabling an in- depth exploration of the spatio-temporal dynamics between neoplastic and stromal cells.

High Environmental Heat Exposure Is a Risk Factor for Acute Kidney Injury and Chronic Kidney Disease.

University of Alabama at Birmingham, Department of Medicine, Division of Nephrology, Section of Cardio-Renal Physiology and Medicine, Birmingham, AL. Electronic address:

Chronic kidney disease of unknown etiology has been reported in Mesoamerican regions and other parts of the world, with increasing evidence pointing to heat stress as a central contributing factor. The incidence of acute kidney injury appears to correlate strongly with heat exposure, as demonstrated in both human and animal studies. The underlying mechanisms of heat-induced kidney injury are likely multifactorial, involving hemodynamic changes, immune responses, and possibly coagulopathies.
