Arachidonic Acid News and Research

RSS

Arachidonic acid is an omega-6 fatty acid that is present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain. It is the counterpart to the saturated arachidic acid found in peanut oil.

Mechanism of fatty-acid coupled adaptive immunity in SARS-CoV-2 revealed

A new study explains how SARS-CoV-2 adapts its immunogenicity to the immune response of the host.

Inflammatory chemicals involved in fat metabolism play key role in ALS, study shows

A new study using genetically engineered mice and human cell and tissue samples has added to evidence that higher levels of inflammatory chemicals involved in fat metabolism occur in people with amyotrophic lateral sclerosis (ALS), the neuromuscular disorder, also known as Lou Gehrig's disease.

Some COX inhibitors/NSAIDs increase COVID-19 severity

A startling new preprint research paper posted to the medRxiv server warns against the use of commonly used non-steroidal anti-inflammatory drugs (NSAIDs) belonging to the category of cyclooxygenase inhibitors (COX inhibitors) in patients with coronavirus disease 2019 (COVID-19).

Lipid storm in severe COVID-19 linked to high COX/LOX pathway activity

A potentially valuable new study discusses the role of lipids in the hyper-inflammatory phenomena that take place within the lungs of patients with severe or critical COVID-19. Involving a large variety of specialized lipids with biological activity, this process includes the generation and release of pro and anti-inflammatory lipids.

Cell nucleus may play role in enabling cells to evade crowded environments

Like people, cells in the human body protect their personal space. They seem to know how much space they need, and if it gets too tight, most cells prefer to break free.

Researchers identify proinflammatory lipids that precede onset of Type 1 diabetes in mouse model, children

Type 1 diabetes, or T1D, is an autoimmune disease in which the body's immune cells - led by inflammatory macrophages - attack and destroy the beta cells of the pancreas that produce insulin.

Direct structural link between SARS-CoV-2 and essential fatty acid

Now, a new study published on the preprint server bioRxiv in June 2020 reports the discovery of a novel free fatty acid (FFA) binding pocket on the SARS-CoV-2 virus that could explain in part the viral effects of hyperinflammation, immune modulation, and membrane structure.

Camelina sativa oil and fatty fish have major beneficial effect on lipid metabolism

Camelina sativa oil and fatty fish are rich in polyunsaturated omega-3 fatty acids, but their health benefits seem to differ.

Researchers develop new probe to detect common target of anti-inflammatory drugs

The Chan group at the Beckman Institute for Advanced Science and Technology has recently developed a probe named CoxFluor, which is able to distinguish between Cyclooxygenase-2, an enzyme that plays a major role in driving the progression of cancer, and Cyclooxygenase-1, which is expressed in all cells.

Scientists discover the change in activity of neutrophils during cancer development

International group of scientists in the joint study of the laboratory of the Wistar Institute, University of Pittsburgh and I.M. Sechenov First Moscow State Medical University discovered the change in activity of one of the immune cells types called neutrophils during the cancer development: they begin to prevent other immune cells from fighting tumor and thus decelerate treatment.

New studies on fat cell filling, history of biochemistry, and ketogenic diet

There's more than one type of fat cell. Besides the white fat that stores triglycerides in lipid droplets in preparation for lean times later, mammals also have heat-generating brown fat, which acts more like a radiator than a storage closet.
