Revealed -- Mosquito genes that could be controlling the spread of killer viruses

...ind pathogen/immune system interactions in disease vector mosquitoes may help us understand why, for example, some types of mosquitoes can transmit a particular human pathogen while others cannot. If those that cannot have evolved an effective immune system that fights off the pathogen, we may be able to us...

Gene therapy study shows safety and statistically significant improvement in Parkinson's disease

... The study used an adeno-associated virus (AAV) vector to deliver an inhibitory gene (glutamic acid decarboxylase or “GAD”) to the subthalmic nucleus (STN) of the brain. In Parkinson’s disease, STN activity is abnormally increased, largely due to a deficit in GABA (gamma-aminobutyric acid), the major inh...

...th the degree of exposure of the subject to insect vector bites. The vector saliva, which is adapted for blood feeds, plays a prime role in the transmission of the associated d...

Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model

...ion, or ED, that were injected with a gene therapy vector containing either of two nerve growth factors were able to regain normal function after four weeks, according to a study conducted by University of Pittsburgh School of Medicine researchers. These findings are being presented at the 10th annual meeti...
