Epithelium, tear down this wall!

Cell Host Microbe. 2009 Jan 22;5(1):1-2. doi: 10.1016/j.chom.2008.12.008.


The presence of bacteria within epithelial-lined compartments, such as the lung, elicits rapid recruitment of innate immune cells. In this issue of Cell Host & Microbe, Chun and Prince (2009) report that epithelial cells facilitate this process by reorganizing their intercellular junctions to enhance immune cell transmigration.
