Specifically, we compared (i) pre-treatment with the MEK inhibitor on day 0 followed by media change and immediate infection on day 2, (ii) simultaneous drug treatment and infection on day 0 followed by media change on day 2, and (iii) infection on day 0 followed by post-treatment initiation on day 2 and media change on day 4. Here, MAP2K7 is linked to infection.
