All the other subsets [including MSP121-specific CD11b—CD11c— B-cells sorted from the same mice and at the same day post-infection as the MSP121-specific AMB (i.e. 35dpi)] clustered on the left of the PC1 axis, and showed differences mostly along the PC2 axis of the PCA plot, which accounts for only 10% of the variance (Figure 7A). This evidence concerns the gene ITGAM and infection.
