The sphingosine 1-phosphate receptor-1 (S1PR1) signals in heterogenous populations of mouse adventitial lymphatic (LEC) and arterial endothelial cells (aEC1, aEC2) to regulate chromatin and the transcriptome, thus affecting their phenotypes.
Notch ligands Jag1 and Dll4 and their effector Ephb2 are required in sinus venosus endocardium for primitive coronary vasculature formation and later for arterial differentiation and maturation of coronary endothelium.
Transcriptome analysis reveals an alternative splicing program induced in the arterial endothelium under low-flow inflammatory conditions by platelet and macrophage recruitment and dependent upon the RNA-binding splice factor Rbfox2.
Identification of a novel source of progenitor cells that form arterial valve leaflets and that, when disrupted, can lead to bicuspid arterial valve, the most common human cardiac malformation.
Arterial myocyte PKD2 channels are activated by vasoconstrictor stimuli, which increases blood pressure, are upregulated during hypertension and cell-specific knockout in vivo reduces both physiological blood pressure and hypertension.
Current evidence does not suggest adverse effects of ACE inhibitors or ARBs in COVID-19 patients and, to the contrary, discontinuing these drugs in these patients may potentially be harmful.
CO2/H+-dependent purinergic signaling by astrocytes provides specialized control of vascular tone in a brainstem respiratory center in a manner that contributes to respiratory behavior.
Single-cell RNA analysis of brain endothelium identifies the angiogenic venous capillary subset and respective resident endothelial progenitors at the origin of CCM lesions, while arterial endothelial cells are unaffected.
