Abstract: Since BoNTs are potential biothreat agents, efforts are being made to develop therapeutic countermeasures for which sensitive in vitro models are required to evaluate the efficacy of potential therapeutic agents. In this report, we tested human neuroblastoma cell lines for their susceptibility to BoNT toxicity and demonstrated the application of these cells to measure the neutralising activity of a BoNT-specific antibody. We demonstrated that SK-N-BE(2)M17 cells are highly sensitive to BoNT/A and /C intoxication and can be used as a cell-based assay to investigate the molecular mechanism of BoNT/A intoxication and to quantitate the neutralising activity of antibodies.
