by University of Virginia Atherosclerosis is a condition affecting the cardiovascular system. If atherosclerosis occurs in the coronary arteries (which supply the heart) the result may be angina pectoris, or in worse cases a heart attack.

Physical fitness in adolescence linked to less atherosclerosis in middle age
by Linköping University Credit: Unsplash/CC0 Public DomainMen who were physically fit when they were young had a lower risk of atherosclerosis almost 40 years later, according to a study led by researchers at Linköping University, Sweden. The findings, published in the British Journal of Sports Medicine, suggest that atherosclerosis is one of the mechanisms behind the...
Researchers uncover new signaling pathway in the development of atherosclerosis
by Ludwig Maximilian University of Munich Pathway synopsis (I.) Sterile inflammation triggers the activation of a subset of cDCs, which respond by releasing CCL17. (II.) In turn, CCL17 binds to CCR8 on cDCs (autocrine) and on CD4+ T cells (paracrine) to stimulate an upregulation of CCL3 expression and release. (III.) Subsequently, CCL3 interacts with CCR1 on...
Study analyzes recent global and national trends of atherosclerosis

Diagnosing atherosclerosis with an oxidative stress biomarker triggered multiplexed instrument
by Thamarasee Jeewandara , Medical Xpress A multiplexed diagnostic tool for detecting intraplaque and urinary MDA. We design a multiplexed diagnostic tool that includes two functions (photoacoustic imaging and urinalysis), for assessing intraplaque and urinary MDA and reliably assessing intraplaque and systematic oxidative stress in atherosclerosis. Credit: Science Advances, DOI: 10.1126/sciadv.adh1037Oxidative stress is fundamental to...
Key molecular pathway affecting atherosclerosis progression discovered
by Medical University of Vienna Credit: Kateryna Kon/Shutterstock Heart attacks and strokes arising from atherosclerosis, which is driven by the accumulation of lipids in the inner linings of arteries, are responsible for about one third of deaths worldwide. Accordingly, atherosclerosis is the focus of intense research aimed at the development of novel effective treatments. A team of researchers from MedUni...
Acetate controls endothelial-to-mesenchymal transition: Potential therapeutic target for reducing atherosclerosis
by Yale School of Medicine In a new study, researchers including Yale School of Medicine’s Michael Simons, MD, identify the molecular underpinnings of persistent endothelial-to-mesenchymal transition (EndMT), an important process related to vascular inflammation in diseases including pulmonary hypertension. Researchers found atypical acetate production from glucose triggered metabolic modulation of the endothelium activated TGF-β signaling, triggering a...
High-fat diet ‘turns up the thermostat’ on atherosclerosis, finds study

High-fat diet ‘turns up the thermostat’ on atherosclerosis
AMERICAN SOCIETY FOR BIOCHEMISTRY AND MOLECULAR BIOLOGY IMAGE: MICROSCOPY IMAGE OF A MOUSE AORTA WITH ATHEROSCLEROTIC LESIONS. PLAQUES ARE SHOWN IN RED. CREDIT: SRINIVASA REDDY In a recent study, researchers determined that derivatives of natural emulsifiers such as phospholipids found in high-fat, high-cholesterol diets can promote atherosclerosis via gut bacteria interactions with the immune system. This...
Irregular Sleep Tied to Markers of Atherosclerosis
Carolyn Crist February 23, 2023 Irregular sleep — such as inconsistent sleep duration or sleep timing — may increase the risk of developing atherosclerosis among adults older than age 45, a new report suggests. In particular, variation in sleep duration of more than 2 hours per night in the same week was tied to higher rates of...
