Question

Draw a cartoon representing the following caption:

Dendritic cells initiate adaptive immune responses.

Immature dendritic cells residing in a tissue take up pathogens and their antigens by macropinocytosis and by receptor-mediated endocytosis. They are stimulated by recognition of the presence of pathogens to migrate through the lymphatics to regional lymph nodes, where they arrive as fully mature nonphagocytic dendritic cells that express both antigen and co-stimulatory molecules necessary to activate a naive t cell that recognizes the antigen. Thus the dendritic cells stimulate lymphocyte proliferation and differentiation.
