Antibodies to the Junctional Adhesion Molecule Cause Disruption of Endothelial Cells and Do Not Prevent Leukocyte Influx into the Meninges after Viral or Bacterial Infection


Lechner, Franziska; Sahrbacher, Ulrike; Suter, Tobias; Frei, Karl; Brockhaus, Manfred; Koedel, Uwe; Fontana, Adriano (2000). Antibodies to the Junctional Adhesion Molecule Cause Disruption of Endothelial Cells and Do Not Prevent Leukocyte Influx into the Meninges after Viral or Bacterial Infection. Journal of Infectious Diseases, 182(3):978-982.

Abstract

A hallmark of infectious meningitis is the invasion of leukocytes into the subarachnoid space. In experimental meningitis triggered by tumor necrosis factor—α and interleukin-1β, the interaction of leukocytes with endothelial cells and the subsequent migration of the cells through the vessel wall can be inhibited by an antibody to the junctional adhesion molecule (JAM). In contrast to the cytokine-induced meningitis model, anti-JAM antibodies failed to prevent leukocyte influx into the central nervous system after infection of mice with Listeria monocytogenes or lymphocytic choriomeningitis virus. Furthermore, in bacterial meningitis, anti-JAM IgG antibodies, but not Fab fragments, caused disruption of the endothelium. Likewise complement-dependent antibody-mediated cytotoxicity was observed in cultured brain endothelial cells treated with anti-JAM IgG but not with its Fab fragment
