Immune response and apoptosis are up-regulated by Pf-IRBC exposure. GO biologic process categories (A) up-regulated and (B) down-regulated were selected from total list obtained based on the number of genes and corrected P value. Only those categories were plotted that showed minimum 8 (up-regulated) or 5 (down-regulated) genes and have corrected P < .05. Numbers associated with each category represent number of genes.
