Trans-vaccenic acid (TVA), a long-chain fatty acid found in meat and dairy products from grazing animals such as cows and sheep, improves the ability of CD8+ T cells to infiltrate tumors and kill cancer cells, according to a new study by researchers from the University of Chicago.
The research, published this week in Nature, also shows that patients with higher levels of TVA circulating in the blood responded better to immunotherapy, suggesting that it could have potential as a nutritional supplement to complement clinical treatments for cancer.
“There are many studies trying to decipher the link between diet and human health, and it’s very difficult to understand the underlying mechanisms because of the wide variety of foods people eat. But if we focus on just the nutrients and metabolites derived from food, we begin to see how they influence physiology and pathology,” said Jing…
