^aShaded and nonshaded cells indicate proteins that were increased and decreased, respectively, in infected cells compared to those in mock-infected FTE cells. Data shown here include proteins with differential of about 3-fold with P < 0.05. For a complete list, see Table S2 in the supplemental material. INF, infinity.

^bP value is from a paired t test with mock-infected and infected FTE cells from 4 donors.
