Abstract

We have examined the macrophage and microglial cell response in mouse brains during the course of acute herpes simplex encephalitis produced by intranasal inoculation of virus. Macrophage infiltration and a microglial cell reaction were detected from 24 h after initial detection of HSV-1 antigen in brain. Macrophage infiltration was confined to focal areas of infection but the microglial cell reaction occurred in a more widespread distribution. Following disappearance of viral antigen, with resolution of the acute infection, macrophage infiltration and a focal microglial cell reaction remained for several weeks, providing a marker of sites of previous infection.

      In addition to CD8+ T cells, microglia also have been suggested to play a role in the immune response to HSV-1 within the CNS. For example, following intranasal inoculation with HSV-1, the brains of BALB/c mice demonstrated widespread microglia proliferation (Esiri et al., 1995). In addition, microglia increase their expression of MHC class I and class II molecules following a corneal HSV-1 infection in rats (Song and Jia, 1999; Weinstein et al., 1990).

      Other MMPs are also capable of degrading gelatin but recent reports indicate MMP-9 as the main protease involved in disruption of the basement membrane during acute CNS inflammation (Asahi et al., 2001; Lo et al., 2002). In acute HSE, encephalitic lesions are in close vicinity to perivascular infiltrates (Chan et al., 1989) and are characterized by edema, necrosis and petechiae (Esiri et al., 1995). Disruption of the BBB is associated with vasogenic edema, which is caused by the shift of intravascular fluid into the extravascular compartment and accompanied by disturbance of the cerebral microcirculation and metabolic disturbances.
