- What is required for B cells to switch isotype and increase antibody affinity?
- T/F: Effector T cells express more adhesion compared to naive T cells
- What 5 types of effector cells can activation of naive CD4 T cells result in?
- T/F: Effector T cells don't need costimulatory molecule interaction (CD28-B7) to respond to their antigens
- How would you expect a TC cell to respond if it encountered a TH cell that was infected with a virus?
- T/F: Effector T cells express integrin VLA-4 which allows them to interact with endothelial cells of blood vessels and extravasate at the sites of infection and inflammation
