Dietary polyphenols may play a role in regulating inflammatory immune responses

PCB2DG, a polyphenol with anti-inflammatory properties, works by targeting and directly interacting with the major glutamine transporter protein, alanine serine cysteine transporter 2 (ASCT2), to inhibit the uptake of glutamine, an important amino acid found in the blood.

Mediterranean diet may benefit health in part by incorporating moderate wine consumption

Many public health warnings have been issued against alcohol consumption, even in small quantities, though the evidence for such strict limits is controversial. The current study, published in the MDPI journal Nutrients, is a narrative review focused on clearing up some of the confusion associated with alcoholic drinks.

Scientists unravel the molecular origin of rare genetic disease cystinosis

The rare genetic disease cystinosis is caused by mutations in the gene for a protein called cystinosin. A team of scientists has now solved the structure of cystinosin and determined how mutations interfere with its normal function, providing insights into the underlying mechanisms and suggesting a way to develop new treatments for the disease.
