In contrast to wt and Δ2B viruses, BCR stimulation of Δ2A and Δ2A/Δ2B virus-infected B cells resulted in significantly reduced LMP1 expression when compared to wt-infected B cells (Δ2A 168 hours p-value <0.05, Δ2A/Δ2B 120 hours p-value <0.0001, Δ2A/Δ2B 168 hours p-value <0.001) (Figure 7C), though the observed effect was most significant for Δ2A/Δ2B infection. The gene discussed is BCR; the disease is infection.
