Two new studies show that a new drug called Cimzia may ease symptoms of Crohn’s disease.

Cimzia hasn’t been approved by the FDA yet. Patients would give themselves injections of the drug, which targets an inflammatory chemical called tumor necrosis factor (TNF) alpha.

The two new studies, published in The New England Journal of Medicine, highlight Cimzia’s clinical trials in Crohn’s disease patients.

A large-scale genomic study has uncovered new genetic variations associated with multiple sclerosis (MS), findings that suggest a possible link between MS and other autoimmune diseases. The study, led by an international consortium of clinical scientists and genomics experts, is the first comprehensive study investigating the genetic basis of MS. Findings appear in the July 29 online edition of the New England Journal of Medicine.

The ebb and flow of such autoimmune diseases as multiple sclerosis, lupus and rheumatoid arthritis has long been a perplexing mystery. But new findings from the Stanford University School of Medicine bring scientists closer to solving the puzzle, identifying a molecule that appears to play a central role in relapses.

The discovery by a six-member Inflammatory Bowel Disease (IBD) Genetics Consortium of a genetic risk factor for IBD has been reported in Science Express, the online publication of the journal Science. According to one of the Canadian principal investigators, director of the Laboratory in Genetics and Genomic Medicine of Inflammation at the Montreal Heart Institute, Dr. John D. Rioux, “This discovery may lead to a paradigm shift in our thinking from ‘genetics of diseases to genetics of health’, particularly as concerns Crohn’s Disease and Ulcerative Colitis.”

Using a new form of microscopy to penetrate living lymph nodes, UCSF scientists have for the first time viewed immune cells at work, helping clarify how T cells control autoimmunity.

The technique, known as two-photon laser-scanning microscopy, was able to focus deep within the lymph node of a diabetic mouse, allowing the researchers to show that immune cells known as T regulatory, or Treg, cells control the destructive action of rogue autoimmune cells when each of the two cell types interact with a third kind of cell.
