FIG 2.

Cytokine production following influenza virus infection in human lung epithelial cells. Calu-3 cells 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. Values represent the means of triplicate independent cultures per virus plus standard deviations. Levels of each analyte in uninfected cells are indicated with a dashed line. An asterisk indicates a statistically significant difference between groups (P < 0.05).
