How do you assess atherosclerosis in mice?

There are a number of methods for the quantification of atherosclerosis in mice and the three vascular beds most commonly analysed are: (i) the aortic root and ascending aorta cut in cross-section (ii) the aortic tree spanning the arch, thoracic and abdominal regions of the aorta opened longitudinally to expose the …

How do you induce atherosclerosis in mice?

Lipid-enriched diets are often used to induce or accelerate the rate of atherosclerotic lesion development in murine models of atherosclerosis. It appears that the induction of persistent hypercholesterolemia to levels >&300 mg/dL is required for the development of experimental atherosclerosis in the mouse.

How are mice used to develop drugs to fight against atherosclerosis?

Stanford researchers have found that drug-coated nanoparticles limit the development of atherosclerosis in mice, without side effects. A new study describes how, in mice, nanotubes carry a molecule that turns off the “don’t eat me” signal given off by diseased and dying cells in artery plaque.

How do you diagnose atherosclerosis symptoms?

Doctors have an arsenal of diagnostic tests and tools they can access to confirm the presence of Atherosclerosis – these include an angiogram (Arteriogram), cholesterol tests, a chest x-ray, a CT (computed tomography) scan, Duplex scanning, an echocardiogram, an electrocardiogram (ECG or EKG), an exercise stress test ( …

What are LDLR mice?

The LDLR−/− mice (low-density lipoprotein, LDL, receptor) are the models for studying familial hypocholestrolemia. These mice have a mutation that affects the LDLR; therefore, they resemble humans in the plasma lipoprotein profile.

What does low-density lipoprotein do?

Low-density lipoprotein (LDL) transports cholesterol from the liver to the tissues of the body. LDL cholesterol is therefore considered the “bad” cholesterol.

What is hypercholesterolemia cholesterol levels?

Hypercholesterolemia is defined as serum total cholesterol of 200 mg/dl or more, according to the National Cholesterol Education Program (NCEP) III guidelines.

What kind of disease does a mouse have?

Although the mice were fed a diet containing about 10 times as much cholesterol as a Western diet, they had relatively small lesions that showed little evidence of progression to fibrous plaques, and lesion formation was limited to the aortic root in contrast to the lesions in humans.

How are wild type mice treated with IL-13?

Minihepcidin PR73 protected iron-loaded Hamp−/− mice from infection by V. vulnificus injected subcutaneously ( Arezes et al., 2015 ). Wild-type mice treated with IL-13 also develop symptoms strikingly reminiscent of human asthma, including mucus overproduction and AiHR. However, there is a mystery here because mouse T cells do not express IL-13R.

Why are wild type mice higher in cholesterol?

The mouse model lacking LDL receptor had twofold higher plasma cholesterol levels than wild-type mice, because of an increase in intermediate density lipoproteins and LDL. 298 Thus, this model has similarity to familial hypercholesterolemia.

What happens to the hippocampus in wild type mice?

WT mice exposed to EE showed an increase in H3 (K9 and K14) and H4 (K5, K8, and K12) acetylation in the hippocampus upon enhancement of associative and spatial learning (Fischer et al., 2007). Wild-type mice treated with IL-13 also develop symptoms strikingly reminiscent of human asthma, including mucus overproduction and AiHR.
