Protein IL-10 removes Escherichia coli K1 bacterium from blood and reverses brain damage

A team of researchers at Childrens Hospital Los Angeles (CHLA), along with colleagues from the Keck School of Medicine of the University of Southern California and the Universite Auvergne, France, have discovered an important role for a small, naturally occurring protein called interleukin-10 (IL-10) in removing bacteria from the blood of infected mice and reversing damage to the brain.

Study demonstrates p53 protein becomes activated during gamete formation

Protein p53 is known as the guardian of the genome since it is basic for the genome's integrity by preventing the accumulation of mutations originating either by the cell's own mechanisms or by the action of external agents.

UAB researchers win grant to study metastasis of dead cancer cells

Researchers with the University of Alabama at Birmingham (UAB) Comprehensive Cancer Center and UAB Department of Chemistry have won an $805,000 grant from the U.S. Department of Defense Breast Cancer Research Program to study whether dead cancer cells left over after treatment encourage cancer's spread to other parts of the body.

Reprogrammed killer cells prevent metastasis

A team of researchers has developed a method to produce cells that kill tumour cells in the lab and prevent tumours forming in mouse models of cancer. Although the current work is in cells and mouse, if the research transfers to human biology, the new type of cell could be a new source for cell-based anticancer therapies.

mPFC dysfunction contributes to compulsive seeking of sexual behavior

Sex "addiction" is a concept that has had particularly high visibility recently with the publicity associated with Tiger Woods. Persons with addictive or compulsive disorders frequently display an inability to inhibit behaviors once they become maladaptive, despite adverse consequences of their behavior. The medial prefrontal cortex (mPFC) is a brain region involved in decision-making and behavioral flexibility, and it has been identified as a potential mediator of behavioral inhibition.

Ginkgo extract EGb 761 promotes formation of new nerve cells, cell connections in brain's memory center

US scientists have shown that the Ginkgo extract EGb 761® promotes the formation of new nerve cells and new cell connections in the hippocampus, the brain's memory center. According to Professor Yuan Luo from the University of Maryland, Baltimore, the Ginkgo constituents responsible for these effects are quercetin and bilobalide.

Study identifies mechanism that interrupts normal p53 gene function leading to tumor development

The p53 gene has been a well-documented player in the prevention of tumors. It is considered the most frequently mutated gene in human tumors with more than half harboring p53 mutations (Bennett et al., 1999). These mutations often can be caused by disruption in normal p53 function.

Neutralizing inhibitory molecules does not improve regeneration in damaged spinal axons

Neuroscientists at the University of California, San Diego School of Medicine have found that removing three key inhibitory molecules from myelin - the insulating material that surrounds nerve cell fibers - does not significantly boost the ability of injured spinal axons to regenerate and restore themselves to full function.

Scientists develop plastic antibody that works in bloodstream of living animal

Scientists are reporting the first evidence that a plastic antibody - an artificial version of the proteins produced by the body's immune system to recognize and fight infections and foreign substances - works in the bloodstream of a living animal. The discovery, they suggest in a report in the Journal of the American Chemical Society, is an advance toward medical use of simple plastic particles custom tailored to fight an array of troublesome "antigens."
