Researchers Ground-Breaking Discovery Finds New Link Between Autoimmune Diseases and a Gut Bacterium

Queen’s University researchers have, for the first time, found a specific microbe in the gut that pumps out protein molecules that mimic a human protein, causing the human defence system to turn on its own cells by mistake. The culprit in this case is called Bacteroides fragilis, a bacterium that normally lives in the human gut. The Queen’s team has shown that this bacterium produces a human-like protein that could

Hypertension Drugs Could Prevent Memory Loss in Lupus Patients, Study Suggests

Researchers from The Feinstein Institute for Medical Research have discovered that the activation of brain cells called microglia likely contributes to the memory loss and other cognitive impairments suffered by many patients with systemic lupus erythematosus (SLE). The study, which will be published September 5 in the Journal of Experimental Medicine, shows that ACE inhibitors—a class of drugs commonly used to treat hypertension—can block this process in mice and might therefore

Small molecule could make a big difference for arthritis patients

Will there come a time when a patient with arthritis can forgo joint replacement surgery in favor of a shot? Keck School of Medicine of USC scientist Denis Evseenko, MD, PhD, has reason to be optimistic. In a new publication in the Annals of Rheumatic Diseases, Evseenko's team describes the promise of a new molecule aptly named "Regulator of Cartilage Growth and Differentiation," or RCGD 423 for short. As its

Stressed Out Interferons Reveal Potential Key to Alternative Lupus Treatment

Only one new drug has become available over the past 50 years for the estimated 1.5 million Americans and five million-plus people worldwide suffering from lupus, but new research has identified a previously unknown mechanism involved in the immune response that could provide an alternative therapy target. Lupus (also known as systemic lupus erythematosus) is a chronic autoimmune disease in which the immune system is unable to distinguish the difference
