Study specifies chemical pathway for ions through the cell membrane

Life ultimately depends on the traffic of tiny charged particles through porous proteins studding the membrane surrounding every cell. In research published in Nature, scientists at The Rockefeller University have for the first time mapped a stepping-stone pathway of amino acids that these charged particles, or ions, follow across cell membranes.

Scientists image transfer of antibodies from mother's milk, to baby's gut

The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases.

Tuberculosis vaccine a step closer

Researchers at Aberystwyth University, following a number of years of investment by the Biotechnology and Biological Sciences Research Council (BBSRC), have licensed ground-breaking research to a non-profit product development partnership working to develop new, more effective vaccines against Tuberculosis (TB). This development will give hope that significantly better prevention and treatment of TB will be available within the next few years.

Reason for body's response to borrelia discovered

Inside a cell it is so crowded that a certain protein from borrelia winds up being crunched. From having been like an oblong rugby football, it gets bent and then collapses into a lump. At this point a previously hidden part appears, known to trigger the formation of antibodies. This explains how Borrelia can be diagnosed, a process that was previously unknown.

FDA licenses Kogenate FS to prevent joint damage in children with hemophilia A

The U.S. Food and Drug Administration has approved a new use for the blood product Kogenate FS to reduce the frequency of bleeding episodes and prevent joint damage in children with the most severe form of hemophilia.

FDA licenses for marketing Cinryze for hereditary angioedema

The U.S. Food and Drug Administration today licensed for marketing the first product in the United States intended to protect people with hereditary angioedema (HAE), a rare and potentially life-threatening genetic disease. HAE affects about 6,000 to 10,000 individuals in the United States.

Tracking down the cause of Mad Cow disease - first synthetic prion protein with an anchor

The cause of diseases such as BSE in cattle and Creutzfeld-Jakob disease in humans is a prion protein. This protein attaches to cell membranes by way of an anchor made of sugar and lipid components (a glycosylphosphatidylinositol, GPI) anchor. The anchoring of the prions seems to have a strong influence on the transformation of the normal form of the protein into its pathogenic form, which causes scrapie and mad cow disease.

On the trail of a targeted therapy for blood cancer

Investigators from the Herman B Wells Center for Pediatric Research at the Indiana University School of Medicine are focusing on a family of blood proteins that they hope holds a key to decreasing the toxic effects of chemotherapy in children and adults.

Discovery of gene variant for cleft lip

About 20 percent of isolated cleft lip, one of the world's most common birth defects, may be due to a one-letter difference in the DNA sequence of a gene involved in facial development, researchers supported by the National Institutes of Health report.

Many receptor models used in drug design may not be useful after all

It may very well be that models used for the design of new drugs have to be regarded as impractical. This is the sobering though important conclusion of the work of two Leiden University scientists published in Science this week.
