Effect of LPS and MALP-2 exposure on TLR4 expression by alveolar macrophages, ATII and TT1 cells.

<p>Using Simple PCI software analysis of images captured by confocal microscopy, the mean fluorescent intensity of staining of individual cells for TLR4 was measured over a 3 hour time course of exposure to LPS (A) or MALP-2 (B). Data expressed as mean ± SE (n = 3 subjects). *P<0.05, **P<0.002, ***P<0.0001.
