A promising new target for future drugs to treat inflammatory bowel disease (IBD) has been found. The study also indicates that another protein, protein kinase C (PKC) λ/ι, may serve as a biomarker of IBD severity. “The intestine is protected by specialized cells, called Paneth cells, that secrete antimicrobial peptides,” said Jorge Moscat, Ph.D., deputy director and professor in the NCI-designated Cancer Center...

Intestinal inflammation in mice can be dampened by subjecting them briefly to a diet restricted in amino acids. The findings, made by Bali Pulendran and colleagues at Emory University, highlight an ancient connection between cellular mechanisms to sense nutrient availability and control of inflammation. They also suggest that a low protein diet – or drugs that mimic its effects on immune cells – could be tools for the treatment of inflammatory bowel diseases, such as Crohn’s disease or ulcerative colitis.
This protective effect was shown to be mediated by molecule GCN2, wh...

Autoimmune diseases, eg type 1 diabetes, Crohn’s disease and juvenile idiopathic arthritis, collectively affect 1 in 12 persons in the Western hemisphere. They represent a significant cause of chronic disability.
“The results from this study enable us to better understand the genetic component of these diseases and how they are genetically related to each other, thereby explaining why different autoimmune disorders often run in the same family,” said Hakon Hakonarson, M.D., Ph.D.
The research encompassed 9 pediatric-onset autoimmune diseases (pAIDs): type 1 diabetes, celiac disease, juvenile idiopathic arthritis, common variable immunodeficiency, systemic lupus eryth...
Read MoreA new study hints we should be paying attention to omega-6, omega-7 for improving/ worsening Crohn’s. Some research has suggested that omega-3 fatty acids can relieve inflammation. Research has suggested high-fat diets may be linked with Crohn’s disease, but never have the 2 been joined through shared genetics. Certain subtle genetic variations — as small as a single-letter change in the DNA — seem to occur more often in people with Crohn’s disease. Separate lines of work show that specific genetic variations are linked to higher levels of some fatty acids (molecular building blocks of fat) in the bloodstream.
In the new study, res...
