FIG 5.

Cytokine production following influenza virus infection in human lung endothelial cells. HULECs were infected with influenza virus at an MOI of 1. Viral titer was determined by standard plaque assay at 24 h p.i. Supernatants were collected at 24 h p.i., and levels of each analyte were quantified by BioPlex. The means from triplicate independent cultures per virus plus standard deviations are shown. Levels of each analyte in mock-infected cells are indicated with a dotted line. An asterisk indicates a statistically significant difference between groups (P < 0.05).
