Chemists identify immune system mechanism for methamphetamine binges

...hemical reactions that occur with the drug when it enters the bloodstream, the researchers showed that methamphetamine reacts with glucose and proteins to form a larger-size "glycated" product. This product is then recognized by immune system components, stimulating the production of antibodies to the drug....

Two years after gene therapy treatments, severe angina patients showed prolonged clinical benefit

...ction site. Inside the cell, the DNA plasmid then enters the nucleus of the cell without a requirement of incorporation into the genomic DNA. The Phase IIb clinical trial expects to see the effect of the expression of DNA-encoded VEGF-2, which in turn stimulates the growth of new blood vessels by promotin...

Discovery of key protein's shape could lead to improved bacterial pneumonia vaccine

...the cell, the pneumococcus breaks free of pIgR and enters the blood, where it can multiply and infect the body. S. pneumoniae is the only bacterium known to use CbpA to invade human cells by binding to pIgR, according to Richard W. Kriwacki, Ph.D., associate member of St. Jude Structural Biology. Kriwacki ...

Success of experimental herpes vaccine builds momentum for human clinical trials

Researchers explore gene treatment to obliterate HIV before it does damage

...n infected person's own cells to destroy HIV as it enters the cell. The process involves removing the patient's stem cells - the ones in the bloodstream that form the different immune system cell types that HIV infects, such as T cells and macrophages - and inserting a gene that produces an HIV-obliterating...

Study finds HIV protein can drive immune cells away

Scientists find HIV-blocking protein in monkeys

...Sodroski, "we've learned quite a bit about how HIV enters cells. More recently, we've developed a picture of the late stages of the viral lifecycle, as it leaves the cell. However, the steps between virus entry and conversion of the viral RNA into DNA have been a black box." A key preparatory step is the re...

Protein helps immune system mount 'instant strike' against deadly flu viruses
