FIG. 5.
Antigen-driven proliferation of murine spleen cells in the presence of recombinant nematode cystatins. Ovalbumin (OVA)-stimulated proliferation of spleen cells of ovalbumin receptor transgenic mice in the presence of a constant amount (0.25 μM) of rCysele1, rCysele2, rAv17, or rOv33. The data shown were obtained with spleen cells from five individual mice.
