Daniel A. Portnoy Pennsylvania, where he collaborated with Dr. Lewis Tilney in the Biology Department and made the observation that "L. monocytogenes" spreads from one cell to another by exploiting a host cell system of actin polymerization. His lab also defined the role of the listerial hemolysin in mediating dissolution of phagosomes. In collaboration with Dr. Philip Youngman, he showed that expression of the "L. monocytogenes" hemolysin by "Bacillus subtilis" led to its growth inside of host cells. Dr. Portnoy collaborated with Dr. Yvonne Paterson, who also arrived at Penn in 1988, on the use of "L. monocytogenes" as a recombinant vector-based vaccine
