Discovery on how an Helicobacter pylori toxin gets into cells

Helicobacter pylori is one tough bug. It can survive in the human stomach, a zone with a pH somewhere between that of lemon juice and battery acid. Now researchers have discovered how an H. pylori toxin gets into cells, a feat that helps the bacterium live in one of the most inhospitable environments in the body

Researchers find multiple cancer genes cooperate to cause malignant cell transformation

Pinpointing new targets for cancer treatments is as difficult as finding a needle in a haystack, yet a University of Rochester team has discovered an entire novel class of genes they believe will lead to a greater understanding of cancer cell function and the next generation of effective and less harmful therapies for patients.

Intracellular antibody mops up mutant protein in Huntington's disease model

Scientists have created a tool for mopping up the clumps of mutant protein that drive neurodegeneration in Huntington's disease. Emory University researchers engineered a virus to make an intracellular antibody or "intrabody" against huntingtin, the protein whose mutant forms poison the brain cells of people with Huntington's.

The emerging role of infection in Alzheimer’s

A number of chronic diseases are in fact caused by one or more infectious agents. For example, stomach ulcers are caused by Helicobacter pylori, chronic lung disease in newborns and chronic asthma in adults are both caused by Mycoplasmas and Chlamydia pneumonia, while some other pathogens have been associated with atherosclerosis. The realization that pathogens can produce slowly progressive chronic diseases has opened new lines of research into Alzheimer's disease.

Scientists back the use of maize as an efficient 'factory' for protein-based pharmaceutical products

Scientists from the Universidad de Lleida (University of Lleida) have published a study confirming that maize seeds are an effective and sure platform within molecular agriculture to alleviate diseases. Over the next few years AIDS could be one of the first diseases to benefit from these results, although regulations for this technology are being developed at the same time as research is being undertaken.
