After decades of studying the pathological process that wipes out large volumes of memory, scientists at The Feinstein Institute for Medical Research discovered a molecule called c-Abl that has a known role in leukemia also has a hand in Alzheimer’s disease. The finding, reported in the June 14th issue of the Journal of Alzheimer’s Disease, offers a new target for drug development that could stave off the pathological disease process.

About half of prostate cancers have a genetic anomaly that appears to make tumor cells responsive to a new class of cancer-fighting drugs, a new study from the University of Michigan Comprehensive Cancer Center finds.

Researchers studying the life threatening infectious disease sepsis have discovered how the infection can lead to a fatal inflammatory response through blood vessel cells. The research, which is published in EMBO Molecular Medicine, focuses on blocking crucial Matrix Metalloprotease enzymes (MMP) which activate the response.

Using a technique that silences genes promoting infection, researchers have developed a novel, topically-applied molecular microbicide capable of preventing HIV transmission. The microbicide is predicted to have long-lasting effects in mice, opening the door to developing an intravaginal microbicide that could protect women against HIV infection potentially for weeks at a time and bolster public health efforts to halt the spread of HIV/AIDS.

Scientists have identified a class of naturally occurring bacteria that can strongly inhibit malaria-causing parasites in Anopheles mosquitoes, a finding that could have implications for efforts to control malaria.

In a study published this month, first author Budd A. Tucker said that he and principle investigator Michael J. Young took skin cells from the tails of rats and used chemical processes to turn them into “induced pluripotent stem cells,” then guided them into becoming precursor cells for retinal neurons.

For the first time, a vaccine has completely protected monkeys against infection with SIV, a virus related to HIV that infects the animals. Out of 24 immunised rhesus macaques, 12 had long-term protection, with no signs of SIV a year after they were deliberately infected with the virus.
