 AB    Herpes simplex virus type I (HSV-1) establishes a latent infection in
       sensory ganglion neurons. During latency no viral-specific proteins are
       detected and virus gene expression is restricted to the
       latency-associated transcripts. We report here that trigeminal ganglia
       of mice with severe combined immunodeficiency contain individual sensory
       neurons exhibiting restricted viral gene expression characteristic of
       latency; this occurred during acute (4-6 days) infection with the
       wild-type HSV-1 strain 17+ and after prolonged (4 weeks) infection with
       the replication impaired HSV-1 mutant in 1814. These results indicate
       that T and B lymphocytes, while important for the recovery from viral
       infections, are not required for the establishment or maintenance of
       latency in neurons.
