1. Meаsles A. (.5 pts) Briefly, describe the prоcess оf B cell аctivаtiоn. Include the key stimulus and any assisting cellular players. B. (.5 pts) Briefly, describe the activation of cytotoxic T-cell activation. Include the key stimulus and any assisting cellular players C. (1 pts) The measles virus primarily infects immune cells and causes "immune amnesia" where memory B and T cells are killed. Describe why the measles virus might lead to a reduction in antibody diversity and what the impact would be on individuals infected with measles. D. (3 pts) Signaling lymphocyte activation molecule (SLAM, also called CD150 because it is designated on the CD150 gene) is an integral membrane protein that is expressed on immune cells and acts as the principle cellular receptor for the measles virus. Describe the steps (think central dogma & include machinery, parts of the cells, and molecules involved) in the cell producing SLAM receptors and presenting it in the outer cell membrane (diagrams encouraged). E. (1 pts) What assay(s) could you use to quantify the number of CD150 positive cells are in cultured blood samples before and after being infected with measles and briefly describe how it works?
