title: Reserpine ameliorates Abeta toxicity in the Alzheimer's disease model in Caenorhabditis elegans.
abstract: Earlier we have reported that reserpine, an antihypertensive drug, known to downregulate biogenic amines through inhibition of the vesicular monoamine transporter (VMAT), increases longevity of Caenorhabditis elegans with a high quality of life, namely, enhanced and prolonged mobility (Srivastava et al., 2008). As neurodegenerative diseases are of adult onset, we addressed the protective ability of reserpine against neurodegenerative diseases, especially Alzheimer's disease (AD). In the well established AD model in C. elegans, Amyloid beta (Abeta) is expressed in the muscles and Abeta toxicity is manifested as paralysis (Link, 1995). In this model, reserpine significantly delayed paralysis and increased the longevity. In addition, reserpine provided thermotolerance, but interestingly the Abeta transcript and expression levels remains grossly unchanged.
