Marburg Virus Glycoprotein Is a Remarkable Virulent Factor Linked to Hemorrhagic Pathology: Evidence from Multimodal Experimental Systems

open access: yesAdvanced Science, EarlyView.
By integrating data from in vitro, ex vivo, and in vivo models, our research identifies the MARV glycoprotein as a remarkable hemorrhagic factor, filling a major gap in this important field. It also provides practical experimental tools for the basic research on viral pathogenesis and applied research aimed at antiviral intervention for hemorrhagic ...

Integrated Regional Cardiac Hemodynamic Imaging and RNA Sequencing Reveal Corresponding Heterogeneity of Ventricular Wall Shear Stress and Endocardial Transcriptome

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundUnlike arteries, in which regionally distinct hemodynamics are associated with phenotypic heterogeneity, the relationships between endocardial endothelial cell phenotype and intraventricular flow remain largely unexplored.

Expression of transient receptor potential channels TRPC1 and TRPV4 in venoatrial endocardium of the rat heart.

open access: yesNeuroscience, 2014
The atrial volume receptor reflex arc serves to regulate plasma volume. Atrial volume receptors located in the endocardium of the atrial wall undergo mechanical deformation as blood is returned to the atria of the heart.

Isovolumic relaxation strain imaging is an accurate and sensitive approach for detection of active diastolic dysfunction: A preclinical study

open access: yesAnimal Models and Experimental Medicine, EarlyView.
A modified approach was developed to accurately identify the isovolumetric relaxation time (IVRT) using an apical three‐chamber view. Compared with conventional echocardiography, isovolumic relaxation strain imaging (IVSI) helps to detect the earlier alternations of diastolic function in transverse aortic constriction (TAC) mice.

Mechanical forces pattern endocardial Notch activation via mTORC2-PKC pathway

open access: yeseLife
Notch signaling has been identified as a key regulatory pathway in patterning the endocardium through activation of endothelial-to-mesenchymal transition (EMT) in the atrioventricular canal (AVC) and proximal outflow tract (OFT) region.

Heg1 and Ccm1/2 proteins control endocardial mechanosensitivity during zebrafish valvulogenesis

open access: yeseLife, 2018
Endothelial cells respond to different levels of fluid shear stress through adaptations of their mechanosensitivity. Currently, we lack a good understanding of how this contributes to sculpting of the cardiovascular system.

Recognition of specific sialoglycan structures by oral streptococci impacts the severity of endocardial infection. [PDF]

open access: yes, 2019
Streptococcus gordonii and Streptococcus sanguinis are primary colonizers of the tooth surface. Although generally non-pathogenic in the oral environment, they are a frequent cause of infective endocarditis.

Learning Shape Representations for Multi-Atlas Endocardium Segmentation in 3D Echo Images

open access: yesThe MIDAS Journal, 2014
As part of the CETUS challenge, we present a multi-atlas segmentation framework to delineate the left-ventricle endocardium in echocardiographic images. To increase the robustness of the registration step, we introduce a speckle reduction step and a new ...

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.
