Dexamethasone restores the expression of VEGF.

<p>Micrographs show the expression of VEGF by immunofluorescence in mice motor cortex after four days of treatment with saline (A and E), LPS (B and F), Stx2 (C and G) and Stx2+LPS (D and H) followed by i.p. injection of saline (without Dexamethasone, A through D) or Dexamethasone (E through H). VEGF expression is quantified under different treatments (I). J: negative control by not adding the primary antibody. *: significant differences between mice treated with Dexamethasone and those treated with saline (p <0.001).
