The Activation of Helper T Cells is Likely

Question

The activation of helper T cells is likely
A)when an antigen is displayed by a dendritic cell.
B)when a cytotoxic T cell releases cytokines.
C)when natural killer (NK)cells come in contact with a tumour cell.
D)in the bone marrow during the self-tolerance test.
E)when B cells respond to T-independent antigens.

Accepted Answer

Helper T cells recognize and bind to antigens that have been presented by antigen-presenting cells, such as dendritic cells. This binding activates the helper T cells to release cytokines and stimulate the immune response.
