Abstract:
:Fas (CD95) and Fas ligand (FasL, CD95L) have been implicated to be involved in the acute inflammatory response by attracting neutrophils and regulating their survival. Increased levels of soluble Fas and FasL are found in cerebrospinal fluid (CSF) samples of patients with bacterial meningitis but not in controls. Functional FasL (gld)- or Fas (lpr)-deficient mice were used to assess their role in the pathophysiology of pneumococcal meningitis. Induction of meningitis in wild-type (WT) mice caused an increase in CSF white blood cell (WBC) count, intracranial pressure (ICP), and vessel permeability, paralleled by a worse clinical status at 24 h. The inflammatory response was accompanied by elevated levels of IL-1beta, MMP-2, and MMP-9 in the brain. Neither gld- nor lpr-mice showed significant differences in the above-mentioned pneumococci-induced pathophysiological alterations. These results indicate that Fas and FasL are not essential in the regulation of the acute inflammatory response during pneumococcal meningitis.
