Gene Therapy For Parkinson's Disease Moves Forward In Animals

...ndel has been working on the idea of introducing a vector into brain that would express GDNF. What they've found is that if you get low-level expression, you can prevent cell death in a part of the brain called the substantia nigra. That's been shown before in rodent models, but it's encouraging to see data...

Researchers identify protein crucial for survival of Lyme-disease bacterium

...it has chosen a tick environment to be its natural vector in nature. "It potentially could give us a target for eradicating the bacterium, because if you understand what it needs to sustain itself, then in theory you could disrupt that cycle by blocking whatever that mechanism is," Dr. Norgard said. Tradi...

The researchers use a modified adenovirus vector vaccine expressing a region of the outer membrane of P. aeruginosa, called OprF, which had previously been recognized as a promising vaccine candidate. This region of the bacteria was expressed in the capsid area of the vector. Immunization of mice w...

Using nanoparticles, in vivo gene therapy activates brain stem cells

...in vivo. "This is the first time that a non-viral vector has demonstrated efficacy in vivo at levels comparable to a viral vector," Bharali said. In the UB experiments, targeted dopamine neurons -- which degenerate in Parkinson's disease, for example -- took up and expressed a fluorescent marker gene, dem...
