Yersinia outer protein E, YopE. A versatile type III effector molecule for cytosolic targeting of heterologous antigens by attenuated Salmonella.
Many Gram-negative pathogens evade the host's immune response by utilizing a specialized protein secretion machinery, known as type III secretion system (TTSS). Virulence factors such as the Yersinia outer protein E (YopE) are delivered directly into the cytosol of target cells in a TTSS-dependent fashion. This unique translocation mechanism can be used by attenuated Salmonella carrier vaccines for the delivery of heterologous antigens fused to YopE into the MHC class I-restricted antigen processing pathway. In orally immunized mice, this novel vaccination strategy results in the induction of pronounced peptide-specific cytotoxic CD8 T cell responses.
