p24 measurements, taken at days 2, 4 and 7, showed that individuals with higher BST-2 expression (dotted line, Figure 5A) significantly associated with lower viral replication, at days 4 and 7 post infection, compared to lower BST-2 expression individuals (solid line, Figure 5A; ANOVA, p<0.001). The gene discussed is BST2; the disease is infection.
