Tangled up with tau

Pathologist Keqiang Ye and his colleagues have identified a new potential drug target in Alzheimer’s disease. It’s called SRPK2 (serine-arginine protein kinase 2).

Depleting this enzyme from the brain using genetic engineering tools alleviates cognitive impairment in an animal model of Alzheimer’s. The result suggests that drugs Cheap Oakleys that target this enzyme could be valuable in the treatment of Alzheimer’s, although additional studies on human brain samples are necessary to fully confirm the findings, Ye says.

The results were published Tuesday in Journal of Neuroscience. The first author is postdoctoral fellow Yi Hong.

Hong and colleagues found that SRPK2 has elevated activity in a mouse model of Alzheimer’s. It acts on tau, one of the two major toxic clumpy proteins in Alzheimer’s. (beta-amyloid is outside the cell and forms plaques, tau is inside and forms tangles). Previous research on SRPK2 indicated that it had something to do with RNA splicing, so its “entanglement” with tau is a surprise.
