We demonstrated that trifluoperazine, a calcium-calmodulin antagonist, blocked the hyperpermeability induced by Vibrio vulnificus cytolysin in in vitro-modeled endothelium and prevented the deaths of mice. Furthermore, compared to tetracycline alone, tetracycline combined with trifluoperazine enhanced the survival rate of V. vulnificus-infected mice, indicating the role of the cytolysin as an important factor in pathogenesis.
