Question

Which of the following are MISMATCHED?

1) B cells: can be activated to produce antibodies
2) regulatory T cells: release inhibitory cytokines to dampen the immune response
3) helper T cells: directly target and kill cancer cells
4) cytotoxic T cells: carry out cellular immune responses

Answer 1

The mismatched statement is that helper T cells directly target and kill cancer cells.

Step-by-step explanation:

The mismatched statement is:

1. B cells: can be activated to produce antibodies
2. regulatory T cells: release inhibitory cytokines to dampen the immune response
3. helper T cells: directly target and kill cancer cells
4. cytotoxic T cells: carry out cellular immune responses

B cells can indeed be activated to produce antibodies. Regulatory T cells release inhibitory cytokines to dampen the immune response. Helper T cells do not directly target and kill cancer cells; their primary function is to help activate and direct functions of immune responses. Cytotoxic T cells carry out cellular immune responses by destroying infected cells. Therefore, the mismatched statement is option 3) helper T cells: directly target and kill cancer cells.
