Question

A biologist identifies a mutant line of mice that lacks the cellular immune response. She suspects that a mutation in these mice affects the ability of host cells to carry out the antigen presentation step during the activation phase. What could the biologist do to test her hypothesis

Answer 1

Answer:

Isolate antigen-presenting host cells from mice known to have an intact cellular immune response and inject these into the mutant mice to see if the normal response can be restored.
