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.

Genetic background plays a role in regulating the metabolism of essential polyunsaturated fatty acids

Genetic background has an effect on the metabolism of the essential polyunsaturated fatty acids alpha-linolenic acid and linoleic acid, a recent study from the University of Eastern Finland shows.

T-cell cytokine and fatty acid work together to trigger a type of cell death

Researchers at the University of Michigan Rogel Cancer Center found that a cytokine, a category of protein that acts as messengers in the body, and a fatty acid can work together to trigger a type of cell death previously defined by studies with synthetic molecules.

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.

Could drugs derived from microalgae be effective against COVID-19?

Researchers discuss the ability of some microalgae metabolites to prevent cytokine storm syndrome during COVID-19.

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.
