Study Notes
Activation of Helper T Cells
- Antigen presentation by antigen-presenting cells (APCs) is required for the activation of helper T cells.
Activation of B Cells
- Cytokines play a crucial role in the activation of B cells in secondary lymphoid organs, enhancing their proliferation and differentiation.
Antigen Recognition by Helper T Cells
- The T cell receptor (TCR) is involved in the specific recognition of antigens by helper T cells.
