The neurotropic JHM strain of mouse hepatitis virus (MHV) causes
acute encephalitis and chronic demyelinating encephalomyelitis in
rodents. Previous results indicated that CD8 T cells infiltrating the
central nervous system (CNS) were largely antigen specific in both
diseases. Herein we show that by 7 days postinoculation, nearly 30% of
the CD4 T cells in the acutely infected CNS were MHV specific by using
intracellular gamma interferon (IFN-

) staining assays. In mice with
chronic demyelination, 10 to 15% of the CD4 T cells secreted IFN-
in response to MHV-specific peptides. Thus, these results show that
infection of the CNS is characterized by a large influx of CD4 T cells
specific for MHV and that these cells remain functional, as measured by
cytokine secretion, in mice with chronic demyelination.
