title: Nonrestricted differential intoxication of cells by pertussis toxin.
abstract: After uptake and retrograde transport pertussis toxin acts by ADP-ribosylating alpha-Gi proteins. We show that uptake via many different receptor proteins followed by retrograde transport and intoxication is not restricted to a particular cell type. The efficiency of cellular intoxication, however, was found to be cell type dependent.
