A Cell-Based Screen for Discovery of a Macrofilaricide

Kelly Johnston and others from the Liverpool School of Tropical Medicine in the United Kingdom will develop a cell line from a parasitic filarial nematode worm that can proliferate continuously in vitro to enable high-throughput screening of candidate anti-filarial drugs. Current drug screening efforts are limited by the complex life cycle of the worms and the difficulties of obtaining sufficient numbers of worms. They will isolate worm cells from various life cycle stages and use a high-content screening approach to monitor thousands of cells cultured under different conditions to increase the probability of detecting a stably growing cell line. Once one or more stable cell lines have been produced, they will establish optimal culture conditions for drug screening assays.
