GMCSF-MOG exhibited inhibitory activity when included in a CFA emulsion
Included in CFA emulsiona | Incidence of EAE | Mean cumulative score | Median cumulative score | Mean maximal score | Median maximal score | % weight loss |
---|---|---|---|---|---|---|
(a) GMCSF-MOG + MOG35-55 | 3 of 6 | 15.7 ± 19.3 | 7.8 | 1.2 ± 1.5 | 0.5 | 4.4% |
(b) GMCSF-MOG | 1 of 6 | 1.1 ± 2.7 | 0.0 | 0.2 ± 0.4 | 0.0 | 4.3% |
(c) MOG35-55 | 6 of 6 | 79.2 ± 36.6 | 83.5 | 3.7 ± 0.5 | 4.0 | 18.9% |
(d) GMCSF-MOG + MOG | 5 of 6 | 47.5 ± 33.7 | 40.5 | 2.8 ± 1.4 | 3.0 | 9.3% |
(e) GMCSF-MOG | 2 of 6 | 10.5 ± 16.4 | 0.0 | 0.8 ± 1.3 | 0.0 | −1.6% |
(f) MOG35-55 | 7 of 7 | 136.7 ± 10.9 | 142.0 | 4.0 ± 0.0 | 4.0 | 20.9% |
(a–c) C57BL/6 mice were immunized on day 0 with 75 nmole of MOG35-55 in CFA (c), with 1 nmole of GMCSF-MOG in CFA (b), or a mix of 75 nmole of MOG35-55 and 1 nmole of GMCSF-MOG in CFA (a). All mice were given i.p. injections of Pertussis toxin on days 0 and 2. Data analysis represented the time course from day 0 through the end of the experiment on day 41. (c) versus(a) and (b); cumulative scores, p = 0.002, p < 0.001; maximal score, p = 0.002, p < 0.001; weight loss, p = 0.068, p = 0.005.
(d–f) B cell-deficient mice were immunized on day 0 with 75 nmole of MOG35-55 in CFA (c), with 2 nmole of GMCSF-MOG in CFA (b), or a mix of 75 nmole of MOG35-55 and 2 nmole of GMCSF-MOG in CFA (a). All mice were given i.p. injections of Pertussis toxin on days 0 and 2. Data analysis represented the time course from day 0 through day 50. Average daily weight loss was calculated as the average of daily body weight measurements from day 10 until the end of experiment, subtracted from the 100% maximal body weight. (f) versus(d) and (e); cumulative scores, p < 0.001, p < 0.001; maximal score, p = 0.002, p < 0.001; maximal weight loss, ns, p < 0.001; average weight loss; p = 0.018, p < 0.001;
