Figure 8. (a) cell counts shown. Legend: Act = active, Intern = internalized the ag, pres II = presenting on MHC II, Dup = in the mitotic cycle, anergic = anergic, resting = not active. (b) symbols as figure above. (c) the virus, the immunoglobulins and the immunocomplexes. (d) concentration of cytokines and interleukins. Inset plot shows danger signal together with leukocyte growth factor IL-2.
