Effective amelioration of EAE by agg Ig-PLP1. (a) Groups of mice (eight per group) were induced for EAE with 100 μg PLP1 and then treated with 300 μg of agg Ig-PLP1 or agg Ig-W in PBS on days 9, 13, and 17 after disease induction. (b) Direct comparison of the disease course of PLP1 peptide induced EAE after treatment with sol Ig-PLP1 (from Fig. 1) versus agg Ig-PLP1 (from 2 a). Each point represents the mean clinical score of eight mice. These results are representative of three independent experiments. The 900 μg agg Ig-PLP1 given to mice contains ∼12 nmol PLP1. This amount is ∼17-fold lower than the 200 nmol given as free PLP1, yet disease modulation was much more effective.
