*Discovery could lead to treatments for muscular dystrophy and ALS*

COLUMBIA, Mo. – Researchers at the University of Missouri have identified a communication breakdown between nerves and muscles in mice that may provide new insight into the debilitating and fatal human disease known as spinal muscular atrophy (SMA).

“Critical communication occurs at the point where nerves and muscles ‘talk’ to each other. When this communication between nerves and muscles is disrupted, muscles do not work properly,” said Michael Garcia, associate professor of biological sciences in the College of Arts and Science and the Christopher S. Bond Life Sciences Center. “In this study, we found that delivery of ‘the words’ a nerve uses to communicate with muscles was disrupted before they arrived at the nerve ending.” (more…)

People Learn While They Sleep, Study Suggests

EAST LANSING, Mich. — People may be learning while sleeping – an unconscious form of memory that is still not well understood, according to a study by Michigan State University researchers.

The findings are highlighted in the Journal of Experimental Psychology: General. (more…)

EAST LANSING, Mich. — Continuing a global effort to prevent malaria infections, Michigan State University researchers have created a new malaria vaccine – one that combines the use of a disabled cold virus with an immune system-stimulating gene – that appears to increase the immune response against the parasite that causes the deadly disease.

At the same time, the group led by Andrea Amalfitano of the College of Osteopathic Medicine also discovered another immune-system stimulating agent – created at MSU and which has been successful in improving immune responses in vaccines for diseases such as HIV – paradoxically made for a less effective malaria vaccine.

Toxin proteins are genetically engineered into our food because they kill insects by perforating body cell walls, and Professor Rikard Blunck of the University of Montreal’s Group for the study of membrane proteins (GÉPROM) has detected the molecular mechanism involved. In recognition of his breakthrough, he received the Traditional Paul F. Cranefield Award of the Society of General Physiologists yesterday evening. (more…)

MU Study Finds Quitting Smoking Enhances Personality Change

COLUMBIA, Mo. – University of Missouri researchers have found evidence that shows those who quit smoking show improvements in their overall personality.

“The data indicate that for some young adults smoking is impulsive,” said Andrew Littlefield, a doctoral student in the Department of Psychology in the College of Arts and Science. “That means that 18-year-olds are acting without a lot of forethought and favor immediate rewards over long term negative consequences. They might say, ‘I know smoking is bad for me, but I’m going to do it anyway.’ However, we find individuals who show the most decreases in impulsivity also are more likely quit smoking. If we can target anti-smoking efforts at that impulsivity, it may help the young people stop smoking.” (more…)
