VEGFA and infection: A significant increase in VEGF expression in the BAL fluid of ANDV-infected hamsters late after infection (day 17) was observed compared to what was seen in normal hamsters, but as expected, the levels of VEGF detected in the BAL fluid of ANDV-infected animals were nearly identical at later times after infection (day 17) regardless of the presence or absence of AMθ (Fig. 6).
