Question

Which cell type activates B cells and coordinates cell-mediated immunity?

1) T cells
2) Natural killer cells
3) Macrophages
4) Dendritic cells

Answer 1

T cells activate B cells and coordinate cell-mediated immunity by destroying infected cells and activating immune responses.

Step-by-step explanation:

T cells are the cell type that activates B cells and coordinates cell-mediated immunity.

Cytotoxic T cells destroy virus-infected cells in the cell-mediated immune response, and helper T cells play a part in activating both the antibody and the cell-mediated immune responses. Suppressor T cells deactivate T cells and B cells when needed to prevent an excessive immune response.
