High levels of immunosuppressant may lead to tumor recurrence

A new study on the incidence of liver cancer after transplant found that high levels of the immunosuppressant cyclosporine favored tumor recurrence and identified blood levels of the drug that should not be exceeded. Lower levels of cyclosporine levels did not affect rejection rates.

Discovery may lead to new drugs to prevent sexually transmitted HIV infection

Scientists have long suspected that HIV hijacks immune cells called dendritic cells to infiltrate the immune system. Now UCLA AIDS Institute researchers have shown that blocking HIV's access to a naturally occurring molecule on dendritic cells may cut their ability to smuggle the virus into other immune cells.

Gene may boost schizophrenia risk

Clues about how a suspect version of a gene may slightly increase risk for schizophrenia are emerging from a brain imaging study by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH). The gene variant produced a telltale pattern of activity linked to production of a key brain messenger chemical.

Anti-malarial drug combo could help address malaria crisis in Africa

Using a combination of two drugs—artemether and lumefantrine—is the most effective way to treat malaria in the areas of Africa where resistance to commonly used malaria drugs is high, concludes a randomised trial published in this week’s issue of The Lancet.
