How Sugar Promotes Inflammation

People who consume sugar and other carbohydrates in excess over a long period of time have an increased risk of developing an autoimmune disease. In affected patients, the immune system attacks the body’s own tissue and the consequences are, for example, chronic inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis, type 1 diabetes and chronic inflammation of the thyroid gland.

New targets for therapy

The underlying molecular mechanisms that promote autoimmune diseases are multilayered and complex...

Suffering from Psoriasis? Blame this Trio of Proteins

New study shows there may be a way to help even more psoriasis patients. About 7.5 million Americans suffer from psoriasis, an autoimmune disease that shows up as patches of red, inflamed skin and painful, scaly rashes. Although there are effective treatments for psoriasis, not everyone responds to these therapies — and for many, the relief is temporary.

“These therapies don’t reduce disease by 100 percent, and they don’t cure the disease” says La Jolla Institute for Immunology (LJI) Professor Michael Croft, Ph.D. “And if you take patients off those drugs, the disease almost always comes back.”

Now Croft and his team in LJI’s Center for Autoimmunity and Inflammation have discovered how a key protein called TWEAK damages skin cells in psoriasis patients...

Link between Crohn’s disease and Fatty Tissue in the Gut revealed

New research led by University of Limerick in Ireland has revealed a direct link between fatty tissue and Crohn’s disease. The study, carried out by researchers at UL along with a team from University Hospital Limerick, is suggesting for the first time that Crohn’s disease, which is an inflammatory bowel condition, may in fact be a fatty intestine condition.

The research, published in leading journal Scientific Reports, has been described as “an exciting starting point” for the further exploration of Crohn’s disease, which affects thousands of people every year in Ireland and internationally.

The study involved body composition analysis of patients with Crohn’s disease using equipment hosted on the UL campus, with the UL team collaborating with gastroenterology and surgical spec...

Fat-Dissolving Bile Acids may help regulate Gut Immunity and Inflammation

Could bile acids—the fat-dissolving juices churned out by the liver and gallbladder—also play a role in immunity and inflammation? The answer appears to be yes, according to two separate Harvard Medical School studies published in Nature.

The findings of the two studies, both conducted in mice, show that bile acids promote the differentiation and activity of several types of T cells involved in regulating inflammation and linked to intestinal inflammatory conditions. They also reveal that gut microbes are critical for converting bile acids into immune-signaling molecules.

The work suggests possible therapeutic pathways for modulating ...
