8 Questions
Which cells target intracellularly infected cells and activate macrophages to become microbicidal?
CD4 Th1 cells
Which cells induce target cells to undergo programmed cell death and release cytotoxic effector proteins contained in their granules?
Cytotoxic CD8 T cells
Which cells bind tightly to target cells for a long time and release their effector molecules directly to the target cell?
Effector T cells
Which cells are particularly important for activating macrophages and B cells that have taken up antigen but may not be expressing co-stimulatory molecules?
CD4 T cells
Which cells target cells infected intracellularly and are hidden from effects of antibodies and cytotoxic CD8 T cells?
CD4 Th1 cells
Which cells release IFNg which inhibits viral replication and increases MHC1?
CD8 cytotoxic T cells
Which cells specifically require co-stimulation when encountering their target cells?
Naïve T cells
Which cells are armed effector T cells, with activation requirements different from naïve T cells?
