Trypanosoma Cruzi Infection-Induced Changes In Cardiac Microvascular Endothelial Cell Morphology And Function, Lyndsey N. Gisclair, Douglas A. Johnston

Introduction. Six to seven million individuals are infected with Trypanosoma cruzi, the causative agent of Chagas disease. With 12,000 deaths annually, chronic Chagas disease remains a significant global health challenge due to persistent vector transmission, increasing non-vector transmission and limited therapeutic options. Chronic Chagas cardiomyopathy is a leading cause of morbidity and mortality, yet the underlying mechanisms remain poorly understood.Gap Statement. Since its initial description more than 100 years ago, research efforts into the cardiomyopathy found in chronic Chagas disease have primarily focused on the contributions of immune cells, cardiomyocytes and cardiac fibroblasts, leaving a significant gap in understanding the …

Heart failure with preserved ejection fraction (HFpEF) accounts for ∼50% of HF cases. The ZSF1-obese rat model recapitulates clinical features of HFpEF including hypertension, obesity, metabolic syndrome, exercise intolerance, and diastolic dysfunction. We utilized a systems-biology approach to define the metabolic and transcriptional signatures to gain mechanistic insight into pathways contributing to HFpEF development. Male ZSF1-obese, ZSF1-lean hypertensive controls, and WKY (wild-type) controls were compared at 14 weeks of age for extensive physiological phenotyping and left ventricle (LV) tissue harvesting for unbiased-metabolomics, RNA-sequencing, and mitochondrial morphology and function. Utilizing ZSF1-lean and WKY controls enabled a distinction between hypertension-driven molecular changes …
Bcg Vaccine-Induced Innate And Adaptive Pulmonary Immunity Correlating With Protective Efficacy Against Mycobacterium Tuberculosis In The Lungs, Mayank Khanna, Alistair J. Ramsay

Background/Objectives: Effective prophylaxis for Mycobacterium tuberculosis (Mtb) requires greater understanding of immune correlates of protection. With renewed interest in BCG as an Mtb vaccine, particularly via the intravenous (IV) route, our objective was to characterize both innate and adaptive immune correlates of vaccine-induced pulmonary immunity as potential biomarkers for protective efficacy in a murine model of Mtb infection. Methods: Mice were given BCG via different routes and some boosted with recombinant virus constructs encoding Mtb Ag85B. Responding innate lymphoid cell (ILC) populations, T cells and B cells were analyzed by fluorescence activated cell sorting (FACS) for surface markers and by …

Atrial and brain natriuretic peptides (ANP and BNP) bind to guanylyl cyclase A/natriuretic peptide receptor A (GC-A/NPRA), stimulating natriuresis and diuresis and reducing blood pressure (BP), but the role of ANP/NPRA signaling in podocytes (highly specialized epithelial cells covering the outer surfaces of renal glomerular capillaries) remains unclear. This study aimed to determine the effect of conditional deletion of podocyte-specific Npr1 (encoding NPRA) gene knockout (KO) in male and female mice. Tamoxifen-treated wild-type control (PD Npr1 f/f; WT), heterozygous (PD-Cre-Npr1 f/+; HT), and KO (PD-Cre-Npr1 f/-) mice were fed a normal-, low-, or high-salt diet for 4 wk. Podocytes isolated …

Through a process termed clot retraction, platelets cause thrombi to shrink and become more stable. After platelets are activated via inside-out signaling, glycoprotein αIIbβIII binds to fibrinogen and initiates a cascade of intracellular signaling that ends in actin remodeling, which causes the platelet to change its shape. Clot retraction is also important for wound healing. Although the detailed molecular biology of clot retraction is only partially understood, various substances and physiological conditions modulate clot retraction. In this review, we describe some of the current literature pertaining to clot retraction modulators. In addition, we discuss compounds from Cudrania trucuspidata, Arctium lappa, …
