Columbia University Medical Center (CUMC) researchers have pinpointed the immune system mechanism that allows a kidney transplant to be accepted without lifelong immunosuppressive drugs, a significant step toward reducing or eliminating the need for costly and potentially toxic immunosuppressant drugs and improving long-term transplant success. The study is published in Science Translational Medicine.

An experimental treatment to stop the body attacking its own nervous system in patients with multiple sclerosis (MS) appears safe in trials. The sheath around nerves cells, made of myelin, is destroyed in MS, leaving the nerves struggling to pass on messages. A study on nine patients, reported in Science Translational Medicine, tried to train the immune system to cease its assault on myelin.

Another step forward has just been taken in the area of synthetic biology. Research teams from Inserm, CNRS (French National Centre for Scientific Research), Montpellier Regional University Hospital and Stanford University, have transformed bacteria into ‘secret agents’ that can give warning of a disease based solely on the presence of characteristic molecules in the urine or blood. To perform this feat, the researchers inserted the equivalent of a computer programme into the DNA of the…

The heart tissue of mammals has limited capacity to regenerate after an injury such as a heart attack, in part due to the inability to reactivate a cardiac muscle cell and proliferation program. Recent studies have indicated a low level of cardiac muscle cell (cardiomyocytes) proliferation in adult mammals, but it is insufficient to repair damaged hearts. Now researchers from the University of Pennsylvania have now shown that a subset of RNA molecules, called microRNAs, is important for…

A 10th of children have a "monkey-like" immune system that stops them developing Aids, a study suggests. The study, in Science Translational Medicine, found the children's immune systems were "keeping calm", which prevented them being wiped out. An untreated HIV infection will kill 60% of children within two and a half years, but the equivalent infection in monkeys is not fatal.
