DR. KIM has been working with genetic mutations that are associated with early-onset familial Alzheimer's disease (FAD).These mutations increase production of ,-amyloid (A,) by increasing cleavage of amyloid precursor protein (APP) by ,- or ,-secretase.Specifically, Dr. Kim has been studying the "Swedish'" FAD mutation in APP, which results in increased ,-secretase cleavage of APP, and mutations in presenilins, which affect the ,-secretase pathway, leading to increased production of highly amyloidogenic A,42.Applying the relatively new technique of RNA interference (RNAi), he has developed small interfering RNAs (siRNA) that can selectively suppress the FAD allele without affecting the wild-type allele.His group has also developed a lentivirus-based delivery system.
