New research published in the Journal of Leukocyte Biology suggests that increased sensitivity to infection in related to chronic alcohol consumption is due to defective host defense responses and treatment with IL-17 prevent this in mice Alcoholism takes a toll on every aspect of a person's life, including skin problems. Now, a new research report appearing in the April 2015 issue of the Journal of Leukocyte Biology, helps explain why this happens and what might be done to address it. In the report, researchers used mice show how chronic alcohol intake compromises the skin's protective immune response. They also were able to show how certain interventions may improve the skin's immune response. Ultimately, the hope is that this research could aid in the development of immune-based therapies to combat skin infection in people who chronically consume alcohol. "The clinical association between alcoholism and severe skin infection is well established," said Corey P. Parlet, Ph.D., a researcher involved in the work from the Department of Pathology at the University of Iowa, Carver College of Medicine, Iowa City, Iowa. "The ability to experimentally model skin immune deficiencies that occur in chronic alcoholics opens up new avenues to test immune-based therapies to better … Continue reading →

Contact Information Available for logged-in reporters only Newswise Researchers at the Mechanobiology Institute (MBI) at the National University of Singapore have discovered that the inherent handedness of molecular structures directs the behaviour of individual cells and confers them the ability to sense the difference between left and right. This is a significant step forward in the understanding of cellular biology. This discovery was published in Nature Cell Biology on 23 March 2015. Cellular decision making Our bodies are made up of hundreds of different types of cells, each of which performs a unique and highly specialized task. Traditionally, the ability of cells to specialize in a given function was attributed to its genetic code. However, it is becoming increasingly clear that cells do not simply live by a set of inherited or pre-determined instructions. Instead, cellular decisions are made dynamically, much like humans make decisions based on the information provided to us by our senses. Although cells do not have the ability to see or hear, they do possess sensory structures that allow them to detect and measure various environmental stimuli. The application of mechanical force to the cell, for example, will be felt and the cell will respond accordingly. … Continue reading →
