Characterization of Tigurilysin, a Novel Human CD59-Specific Cholesterol-Dependent Cytolysin, Reveals a Role for Host Specificity in Augmenting Toxin Activity

Ifrah Shahi, Sophia A. Dongas, Juliana K. Ilmain…·Adam J. Ratner

This study characterizes tigurilysin, a novel hCD59-specific CDC, showing it requires both hCD59 and cholesterol for activity and exhibits increased lysis efficiency due to host specificity.
