Question 1
The perforin-granzyme pathway involves
◦ the production of antibodies toward the invading pathogen.
◦ the production of fever, which kills the pathogen.
◦ binding CD95L to infected cells, which eventually leads to cell apoptosis.
◦ presenting the foreign antigen to B cells.
◦ the production of special cell-killing proteins that act on infected or abnormal cells.
Question 2
The immunological synapse refers to the
◦ activation of a B cell to become a plasma cell.
◦ interaction between a T cell and an antigen-presenting cell to produce a specialized cell-to-cell contact area.
◦ interaction of the many cytokines produced by different immunological cells.
◦ binding of a monocyte or macrophage to antigen so that it can act as an antigen-presenting cell.
◦ interaction between lymphocytes and foreign antigens to produce memory cells.
