CD8A and infection: We compared lung inflammation in mice developmentally exposed to vehicle or BPA at three critical times following influenza A virus infection: 1) during the peak of virus replication in the lung (day 3 post-infection [p.i.]), 2) during early virus clearance phase (day 7 p.i.), and 3) during the peak of CD8+ T cell mediated response, which ultimately clears virus from the lung and generally dictates the overall outcome of the disease (day 10 p.i.).
