Researchers studying multiple sclerosis (MS) have long been looking for the specific molecules in the body that cause lesions in myelin, the fatty, insulating cells that sheathe the nerves. Nearly a decade ago, a group at Mayo Clinic found a new enzyme, called Kallikrein 6, that is present in abundance in MS lesions and blood samples and is associated with inflammation and demyelination in other neurodegenerative diseases. In a study published in Brain Pathology, the same group found that an antibody that neutralizes Kallikrein 6 is capable of staving off MS in mice.

Collaborative research by groups headed by scientists Joan J. Guinovart and Marco Milán at the Institute for Research in Biomedicine (IRB Barcelona) has revealed conclusive evidence about the harmful effects of the accumulation of glucose chains (glycogen) in fly and mouse neurons.

Mice got new vision and revived heart muscles and monkeys were able to flex muscles in paralyzed hands in research reported today that has extended the boundaries of regenerative medicine beyond the test tube.

A Northwestern Medicine scientist has developed the first blood test to diagnose major depression in teens, a breakthrough approach that allows an objective diagnosis by measuring a specific set of genetic markers found in a patient’s blood.

A recent study finds that a new compound reverses many of the major symptoms associated with Fragile X syndrome (FXS), the most common form of inherited intellectual disability and a leading cause of autism. The paper, published by Cell Press in the April 12 issue of the journal Neuron, describes the exciting observation that the FXS correction can occur in adult mice, after the symptoms of the condition have already been established.

Expanding on previous research providing proof-of-principle that human stem cells can be genetically engineered into HIV-fighting cells, a team of UCLA researchers have now demonstrated that these cells can actually attack HIV-infected cells in a living organism.

A potential new treatment for type 2 diabetes targets the hormone glucagon instead of insulin, according to a new study in mice.

Alzheimer’s disease (AD) is now the sixth leading cause of death among Americans. There is currently no treatment that alters the course of this disease. However, an increasing amount of evidence suggests that changes in the way the body handles iron and other metals like copper and zinc may start years before the onset of AD symptoms. A study using rabbits shows that reducing iron levels in blood plasma may protect the brain from changes related to AD.

Researchers rely on zebra fish for many kinds of cancer studies because their genomes and immune systems are similar in many ways to their human counterparts. A little genetic modification, and poof! They can easily mimic human cancers, explains Nikolaus Trede, a researcher at the Huntsman Cancer Institute at the University of Utah.

A GROUP of mice have returned to Earth after the longest mission any animal has endured in space. The mice were floating around for 91 days to test a way to prevent the breakdown of bone.

A drug developed by Baker IDI scientists could help treat Duchenne Muscular Dystrophy (DMD), a severe and progressive muscle wasting disease that affects young boys, according to a study published today in Nature.

Babies who are born small have a tendency to put on weight during childhood and adolescence if allowed free access to calories. However, an animal model study at UCLA found when small babies were placed on a diet of moderately regulated calories during infancy, the propensity of becoming obese decreased.

Research conducted by the University of Minnesota’s College of Veterinary Medicine could help owners of severely epileptic dogs predict, control and more effectively treat their pets’ seizures.

New figures from the Centers for Disease Control (CDC) show autism is on the rise, affecting one in 88 children born. It’s a growing health problem. Scientists in San Antonio are using an animal model to help find answers to this mysterious condition.

Those with type II diabetes are at two to three times the risk of developing primary liver cancer. But new research from the University of Maryland shows that a common drug many patients already take may prevent the cancer. Studies on animals show that the diabetes drug metformin may help prevent liver tumors from growing.

A new animal model of nerve injury has brought to light a critical role of an enzyme called Nmnat in nerve fiber maintenance and neuroprotection. Understanding biological pathways involved in maintaining healthy nerves and clearing away damaged ones may offer scientists targets for drugs to mitigate neurodegenerative diseases such as Huntington’s and Parkinson’s, as well as aid in situations of acute nerve damage, such as spinal cord injury.

Researchers may have found a new way to treat pancreatic tumors, one of the deadliest and most drug-resistant forms of cancer. Injecting mice with a molecule that melts the tough structure around the tumor allowed a standard chemotherapy drug to better penetrate and destroy cancer cells. The strategy is already being tested in people.
