Assignment:

CTLs are a subset of T cells that express the molecule CD8 on the surface of cells and contain granules filled with proteins that can cause death to the infected cells. In the right circumstances, when they bind to antigen, they will release the granules contents a "lethal payload". The granules content induces apoptosis in the cells that display the antigen. What type of pathogen cannot be controlled by CTLs?
