---|---|---|---|
CD4+ T Cells | CD8+ T Cells | B220+ B Cells | |
Rat IgG | 13 | 3 | 9 |
PC61 | 49 | 14 | 24 |
C57BL/6 mice that had received three i.p. injections of either rat IgG orPC61 were immunized by standard protocol with mouse MOG, then sacrificed on day 20. Mononuclear cells were isolated from the CNS and stained with anti-CD4, anti-CD8 and anti-B220 antibodies as described in Methods. Cell frequencies were used to calculate the absolute cell numbers of each population out of the total number of isolated cells.
