Putting the work of B and T cells together Adaptive immunity: Putting the work of B and T cells together

The need for both innate and adaptive immunity:

1. T cells find their target (MHC/peptide) 2. Appropriate T cells are trapped in lymph tissue 3. Effector T cells leave nodes

Which type of helper T cell will you become? Stimulate macrophages Stimulate B cells

Antigen presentation affects T cell type:

How do effector T cells find their target sites?

Red = defense mechanism Yellow = protective immunity

The immune response to mucosal invasion:

Oral Tolerance:  T cells involved Inflammatory response not induced Antigen not presented by M cells

Immunological memory: Quantitative and qualitative changes
