Can a nicotine vaccine cure smokers?
If smoking a cigarette no longer delivers pleasure, will smokers quit? It's the idea behind a nicotine vaccine being created by MIT and Harvard researchers, in which an injection of synthetic nanoparticles prompts the immune system to create antibodies. The antibodies bind to incoming nicotine molecules so that they're too large to cross the blood-brain barrier. If the brain doesn't know you're smoking, you don't experience the normal smoking kick.
The Boston-based start-up company Selecta Biosciences has tested the SEL-068 vaccine in the lab and is beginning safety tests in humans, making SEL-068 the first synthetic nanoparticle vaccine to be tested in human clinical trials. If successful, the vaccine would be the first synthetically engineered nanoparticle vaccine, distinct from conventionally manufactured biological vaccines.
Although nicotine is not a virus, the nanoparticles target the chemical as if it were by initiating an immune response. Selecta is using the same strategy to design other synthetic vaccines for non-virus ailments including malaria, cancer, diabetes, and transplant rejection. Once a person receives the nicotine vaccine, the effects should last for several years. Read more here...
