Cotinine for Alzheimer's Treatment

A compound derived from tobacco, cotinine, reduced beta-amyloid plaque aggregation in the brain's of mice with the Alzheimer's disease model. The treated mice also performed better on tasks measuring working memory.

Intractable Pain Treatment

Investigators conducted a phase 1 trial of intradermal NP2, a novel gene transfer vector, which was found to be safe and well tolerated for the treatment of intractable pain resulting in pain relief in cancer patients who were unresponsive to morphine or other treatments.

Drosophila Model for Alzheimer's Disease

Joshua Shulman,MD,PhD , instructor of neurology at Harvard medical school used the drosophila model for Alzheimer's disease to determine how variants function. The drosophila tauopathy model, which exhibits age-dependent neurodegeneration, decreased lifespan and hyperphophorylated and misfiled tau protein. The model is used to functionally screen candidate genes in AD which may lead to sooner treatment options for afflicted patients.
