Fig. 3From: The critical role of lipopolysaccharide in the upregulation of aquaporin 4 in glial cells treated with Shiga toxinPhosphorylation of ERK was decreased in B92 glial cells, 20 min after stimulation with Stx-2 and LPS, or Stx-2 alone (a). Phosphorylation of ERK was decreased in B92 glial cells, 20 min after stimulation with Stx-2 and LPS, but not LPS alone (b). Values are presented as means ± SEM. *P < 0.05, **P < 0.01Back to article page
