Micromolar concentrations of adenosine triphosphate (ATP) and its non-hydrolyzable analog &bgr;- &ggr; -methylene ATP are both effective depolarizing chemorepellents in Tetrahymena thermophila. Chemorepellent behavior consists of repeated bouts of backward swimming (avoidance reactions) that can easily be quantified to provide a convenient bioassay for purinergic reception studies. Chemosensory adaptation occurs following prolonged exposure (10 min) to the repellents, and cells regain normal… CONTINUE READING
