Figure 8From: Lung endothelial cells are sensitive to epsilon toxin from Clostridium perfringensEndothelial cells from mice lungs express the MAL protein. Immunohistochemistry assays against the MAL protein (A and C) or Etx (B and D) on lung sections from mice injected with PBS (A, B) or GFP-Etx (C, D). MAL protein expression in the endothelial cells of some vessels was present in both PBS- and GFP-Etx-injected mice (brown, arrowheads in A and C, respectively). Etx was present in GFP-Etx-injected mice (brown, arrowhead in D) but not in the PBS control mice (arrowheads in B). Note unspecific staining from blood cells inside vessels in all conditions (brown, asterisk in A–D). Nuclei were stained with hematoxylin. Scale bar 25 µm.Back to article page
