Question

An antigen has invaded a mammal's body. Specific immune cells engulf and ingest it. Some of the digested pieces are displayed on the cells' bodies. What happens next?

A) B cells are activated and release antibodies

B) T cells are activated and produce clones

C) B cells withdraw the immune response as the antigen is killed

HELP!?!?!?!

Answer 1

I go with C

Answer 2

A nice question...this is a mechanism of forming memory cells in immune system so that in future if infection occurs again our immunity can fight against it.
As specific immune cells engulf and ingested the antigen so it is Cell Mediated Immunity (CMI) and cells here involved are T cells..
Correct option is B. T cells will activate and form clones which acts as memory for future
