Figure 5.

Absence of apoptosis in eritoran tetrasodium–treated corneal epithelium. Mice were pretreated with 2.2 µg antagonist before LPS, as described in Figure 4. The eyes were snap frozen and 5-µm sections were stained using the TUNEL assay and counterstained with DAPI to identify individual cells. Note that the only TUNEL-positive cells are in the corneal stroma and correspond to the presence of neutrophils.
