Bacterial Vector - an overview | ScienceDirect Topics
The most commonly used bacterial vector for vaccine development is Listeria monocytogenes (Lm), a gram-positive intracellular facultative anaerobe. Once inside the phagosome, Lm secretes the membrane-active virulence factors LLO and phospholipase C, which degrade the phagolysosomal membrane, enabling entry into the cytoplasm where expressed ...
Bacterial Vector - an overview | ScienceDirect Topics
Attenuated or nonpathogenic bacteria and viruses may be used as a carrier, or vector, to deliver genes encoding the vaccine target antigen. The insertion of genes into the vector genome allows for delivery of the vaccine antigen to particular anatomic sites (e.g., gut-associated lymphatic tissue) and antigen presentation pathways.
