Figure 3

Effects of anti-LFA-1 and anti-Mac-1 antibodies on severe sepsis cytokine mixture (SSCM)-induced PMN adhesion to hCMEC/D3. PMN were first stimulated with CCM or SSCM for 10 minutes and subsequently treated with anti-LFA-1 or anti-Mac-1 function neutralizing antibody (or control isotype antibody) for an additional 15 minutes. PMN adhesion to stimulated PMN (A) or stimulated PMN and hCMEC/D3 (B) was assessed in the presence of flow (laminar shear stress 0.7 dyn/cm2). n = 4. *P <0.05 as compared to corresponding control cytokine mixture (CCM); # P <0.05 as compared to isotype IgG treatment. CCM-control cytokine mixture; SSCM-severe sepsis cytokine mixture; hCMEC/D3-human cerebral microvascular endothelial cells/D3; PMN-polymorphonuclear leukocytes; IgG-immunoglobulin G; LFA-1 - lymphocyte function-associated antigen 1; Mac-1 - macrophage-1 antigen.
