The innate immune response together with antibodies are generally not effective at clearing infections established by pathogens that replicate inside host cells. The evolution of T cells has provided a means for the immune response to ‘see’ intracellular infections based on the ability of T cells to: Secrete cytokines that diffuse into the infected tissue Activate type I interferon production by macrophages and dendritic cells Activate macrophages to induce inflammation Recognize pathogen-derived peptides on host MHC surface molecules Express cytoplasmic sensors for detecting pathogen-derived nucleic acids

Question
The innate immune response together with antibodies are generally not effective at clearing infections established by pathogens that replicate inside host cells. The evolution of T cells has provided a means for the immune response to ‘see’ intracellular infections based on the ability of T cells to:
- Secrete cytokines that diffuse into the infected tissue
- Activate type I interferon production by macrophages and dendritic cells
- Activate macrophages to induce inflammation
- Recognize pathogen-derived peptides on host MHC surface molecules
- Express cytoplasmic sensors for detecting pathogen-derived
nucleic acids
