Researchers Identify Unexpected Player in Intestinal Immunity

Washington University in St. Louis

With every meal, immune cells in the intestine stand like sentries at a citadel, turning away harmful bacteria but allowing vitamins and nutrients to pass. Now, researchers at Washington University School of Medicine in St. Louis have identified the cells that chaperone food antigens, or proteins, in the intestine so that the immune system doesn’t mount an attack. Their discovery provides scientists with a potential target for therapies against inflammatory bowel disease, celiac disease and food allergies.

Epigenetic Signatures Direct the Repair Potential of Reprogrammed Cells

Tufts University

A research team has reprogrammed skin cells to identify epigenetic signatures that regulate the expression of a protein critical for repair of non-healing wounds. Identification of these signatures holds promise for future research aimed at applying these cells for personalized tissue regeneration.

Correcting Human Mitochondrial Mutations

University of California, Los Angeles (UCLA), Health Sciences

Researchers at the UCLA stem cell center and the departments of chemistry and biochemistry and pathology and laboratory medicine have identified, for the first time, a generic way to correct mutations in human mitochondrial DNA by targeting corrective RNAs, a finding with implications for treating a host of mitochondrial diseases.

Sending Out an SOS: How Telomeres Incriminate Cells That Can't Divide

Salk Institute for Biological Studies

The well-being of living cells requires specialized squads of proteins that maintain order. Degraders chew up worn-out proteins, recyclers wrap up damaged organelles, and-most importantly-DNA repair crews restitch anything that resembles a broken chromosome. If repair is impossible, the crew foreman calls in executioners to annihilate a cell. As unsavory as this last bunch sounds, failure to summon them is one aspect of what makes a cancer cell a cancer cell.

Insulin, Nutrition Prevent Blood Stem Cell Differentiation in Fruit Flies

University of California, Los Angeles (UCLA), Health Sciences

UCLA stem cell researchers have shown that insulin and nutrition keep blood stem cells from differentiating into mature blood cells in Drosophila, the common fruit fly, a finding that has implications for studying inflammatory response and blood development in response to dietary changes in humans.

Researchers Discover Mechanism in Cells That Leads to Inflammatory Diseases


Cedars-Sinai researchers have unlocked the mystery of how an inflammatory molecule is produced in the body, a discovery they say could lead to advances in the treatment of rheumatoid arthritis, Type 2 diabetes and numerous other chronic diseases that affect tens of millions of people.

Discovery of Hair-Cell Roots Suggests the Brain Modulates Sound Sensitivity

University of Illinois at Chicago

The hair cells of the inner ear have a previously unknown "root" extension that may allow them to communicate with nerve cells and the brain to regulate sensitivity to sound vibrations and head position, researchers at the University of Illinois at Chicago College of Medicine have discovered.

Researchers Develop Powerful Tool to Measure Metabolites in Living Cells

NewYork-Presbyterian Hospital/Weill Cornell Medical Center/Weill Cornell Medical College

By engineering cells to express a modified RNA called "Spinach," researchers have imaged small-molecule metabolites in living cells and observed how their levels change over time. Metabolites are the products of individual cell metabolism. The ability to measure their rate of production could be used to recognize a cell gone metabolically awry, as in cancer, or identify the drug that can restore the cell's metabolites to normal.
