2) You encounter a patient that has been found to have an inability to mount an immune response to bacterial infections other than IgM. Suppose the following are plausible issues: 1) The patient is lacking Macrophages able to present antigens to T Cells (ergo only getting a B-Cell response without T Cell activation) 2) The patient either lacks expression of CD 40 (B Cell) or CD 40L (T Cell) 3) A B cell mutation has occurred within the IgA gene. Come up with a plausible test to evaluate each condition and indicate what a result that would indicate the problem.
