Multiple Choice

Which of the following are MISMATCHED?

helper T cells: directly target and kill cancer cells

B cells: can be activated to produce antibodies

cytotoxic T cells: carry out cellular immune responses

regulatory T cells: release inhibitory cytokines to dampen the immune response

Verified step by step guidance

Understand the role of helper T cells: Helper T cells are a type of T cell that play a crucial role in the immune system by activating other immune cells, such as B cells and cytotoxic T cells, but they do not directly target and kill cancer cells.

Review the function of B cells: B cells are a type of white blood cell that can be activated to produce antibodies, which are proteins that specifically target and neutralize pathogens.

Examine the role of cytotoxic T cells: Cytotoxic T cells are responsible for carrying out cellular immune responses by directly attacking and killing infected or cancerous cells.

Consider the function of regulatory T cells: Regulatory T cells help maintain immune system balance by releasing inhibitory cytokines, which dampen the immune response to prevent excessive reactions.

Identify the mismatch: Based on the roles described, the mismatch is 'helper T cells: directly target and kill cancer cells,' as this is not their function. Helper T cells assist other cells in the immune response rather than directly killing cells.
