Table 2. Example of percentages of positive cells for CD80, MHC II, CD40, and CD86, 24 h after contact with PBS (negative control), LPS (positive control at 1μg/ml), and NPs-MPLA at 4 different loading ratios of MPLA.

% of positive cells	PBS	LPS	NPs-MPLA 0.025%	NPs-MPLA 0.05%	NPs-MPLA 0.1%	NPs-MPLA 0.2%
CD80	91.5	95.1	94.5	94.2	95.5	88.8
MHC II	90.5	95.5	94.5	93.9	96.6	94.4
CD40	73.5	81	73.2	73.3	76.6	76.8
CD86	11.2	70.3	64.1	54.6	44.9	43.1
