Preclinical Evaluation of Fingolimod in Rodent Models of Stroke With Age or Atherosclerosis as Comorbidities
This study used a rigorous study design in normal male C57BL/6JOlaHsd mice and in mice with common stroke comorbidities to further evaluate the translational potential of fingolimod. Stroke was induced via middle cerebral artery electrocoagulation in 8-9-week old mice (young mice), 18 month old mice (aged mice), and in high-fat diet-fed 22-week old ApoE-/- mice (hyperlipidaemic mice). Recovery was evaluated using motor behavioural tests 3 and 7 days after stroke. Tissue damage was evaluated at 7 days. A lower dose of fingolimod, 0.5 mg/kg, but not 1 mg/kg, increased lesion size but decreased ipsilateral brain atrophy in yo...

Dog models of human atherosclerotic cardiovascular diseases
Mamm Genome. 2022 Oct 15. doi: 10.1007/s00335-022-09965-w. Online ahead of print.ABSTRACTCardiovascular diseases (CVD) are one of the leading causes of death worldwide. Eighty-five percent of CVD-associated deaths are due to heart attacks and stroke. Atherosclerosis leads to heart attack and stroke through a slow progression of lesion formation and luminal narrowing of arteries. Dogs are similar to humans in terms of their cardiovascular physiology, size, and anatomy. Dog models have been developed to recapitulate the complex phenotype of human patients and understand the underlying mechanism of CVD. Different methods, inc...

IL-19 Regulates Atherosclerotic Plaque Progression via Lymphangiogenesis
CONCLUSION & SUMMARY: These data suggest that IL-19 increases lymphatic vessel formation, potentially allowing RCT to take place to decrease plaque burden in atherosclerosis. Further studies will confirm IL-19's mechanistic pathway in LECs. We will also determine RCT and inflammatory cell trafficking by intravital microscopy. These results have the potential to shift our understanding toward a positive view of the association between the lymphatic system and atherosclerosis.PMID:35554476 | DOI:10.1096/fasebj.2022.36.S1.R5435

DL-3-n-butylphthalide improves the endothelium-dependent vasodilation in high-fat diet-fed ApoE < sup > -/- < /sup > mice via suppressing inflammation, endothelial necroptosis and apoptosis
This study aims to explore whether NBP is able to improve endothelium-dependent vasodilation in atherosclerosis and the underlying mechanisms. Male ApoE-/- mice were fed with a high-fat diet (HFD) for 9-16 weeks to establish a model of atherosclerosis. NBP were given to the mice after eating HFD for 6 weeks and atorvastatin served as a positive control. The endothelium-dependent vasodilation, the blood flow velocity, the atherosclerotic lesion area, the serum levels of lipids, inflammatory cytokines and necroptosis-relevant proteins (RIPK1, RIPK3 and MLKL), and the endothelial necroptosis and apoptosis within the aorta wer...

Endothelial Cell CD36 Reduces Atherosclerosis and Controls Systemic Metabolism
Front Cardiovasc Med. 2021 Nov 23;8:768481. doi: 10.3389/fcvm.2021.768481. eCollection 2021.ABSTRACTHigh-fat Western diets contribute to tissue dysregulation of fatty acid and glucose intake, resulting in obesity and insulin resistance and their sequelae, including atherosclerosis. New therapies are desperately needed to interrupt this epidemic. The significant idea driving this research is that the understudied regulation of fatty acid entry into tissues at the endothelial cell (EC) interface can provide novel therapeutic targets that will greatly modify health outcomes and advance health-related knowledge. Dysfunctional ...

Apolipoprotein C3-Rich Low-Density Lipoprotein Induces Endothelial Cell Senescence via FBXO31 and Its Inhibition by Sesamol In Vitro and In Vivo
In this study, we aimed to examine the effects of ApoC3-rich low-density lipoprotein (AC3RL) mediated via FBXO31 on endothelial cell (EC) senescence and its inhibition by sesamol. AC3RL and ApoC3-free low-density lipoproteins (LDL) (AC3(-)L) were isolated from the plasma LDL of patients with ischemic stroke. Human aortic endothelial cells (HAECs) treated with AC3RL induced EC senescence in a dose-dependent manner. AC3RL induced HAEC senescence via DNA damage. However, silencing FBXO31 attenuated AC3RL-induced DNA damage and reduced cellular senescence. Thus, FBXO31 may be a novel therapeutic target for endothelial senescen...

Hawthorn fruit acid consumption attenuates hyperlipidemia-associated oxidative damage in rats
CONCLUSION: HFA administration can provide health benefits by counteracting the effects of hyperlipidemia caused by an HFD in the body, and the underlying mechanism of this event is closely related to the activation of the Nrf2/HO-1 signaling pathway.PMID:35990322 | PMC:PMC9384962 | DOI:10.3389/fnut.2022.936229

Crosstalk between neurological, cardiovascular, and lifestyle disorders: insulin and lipoproteins in the lead role
Pharmacol Rep. 2022 Sep 23. doi: 10.1007/s43440-022-00417-5. Online ahead of print.ABSTRACTInsulin resistance and impaired lipoprotein metabolism contribute to a plethora of metabolic and cardiovascular disorders. These alterations have been extensively linked with poor lifestyle choices, such as consumption of a high-fat diet, smoking, stress, and a redundant lifestyle. Moreover, these are also known to increase the co-morbidity of diseases like Type 2 diabetes mellitus and atherosclerosis. Under normal physiological conditions, insulin and lipoproteins exert a neuroprotective role in the central nervous system. However, ...
