Increased levels of soluble Fas receptor and Fas ligand in the cerebrospinal fluid of HIV-infected patients.

Abstract:

:Analyses of serum samples and blood cells have revealed a dysregulation of the Fas/Fas ligand (FasL) system during HIV infection, which may be related to disease progression. As Fas and FasL have been suggested to participate in brain injury in a variety of CNS disorders, the aim of this study was to determine (1) whether soluble Fas and FasL can be detected in cerebrospinal fluid (CSF) samples from HIV-infected patients, (2) whether levels of these molecules are related to disease progression, and (3) whether levels of sFasL are related to other laboratory findings. Soluble Fas was detected in 38 of 56 (68%) and soluble Fas ligand in 17 of 56 (30%) CSF samples from HIV-infected patients. CSF levels of both molecules correlated neither with the CSF-to-serum albumin ratio nor with corresponding serum concentrations. This finding suggests that they are at least in part produced intrathecally. Levels of both CSF sFas and sFasL correlated significantly and inversely with the blood CD4+ cell counts, suggesting that the intrathecal release of both molecules is increased during progression to advanced immunodeficiency.
