cells have been observed in animal models of
influenza and sendai virus infections, as well as in patients infected with human immunodeficiency virus and herpes simplex virus type 1 (HSV-1). However, a direct role for TCR-
/
cells in protective immunity for pathogenic viral infection has not been demonstrated. To define
the role of TCR-
/
cells in anti-HSV-1 immunity, TCR-
/
mice treated with anti-
TCR-
/
monoclonal antibodies or TCR-
/
× TCR-
/
double-deficient mice were
infected with HSV-1 by footpad or ocular routes of infection. In both models of HSV-1 infection, TCR-
/
cells limited severe HSV-1-induced epithelial lesions and greatly reduced mortality by preventing the development of lethal viral encephalitis. The observed protection
resulted from TCR-
/
cell-mediated arrest of both viral replication and neurovirulence. The
demonstration that TCR-
/
cells play an important protective role in murine HSV-1 infections supports their potential contribution to the immune responses in human HSV-1 infection. Thus, this study demonstrates that TCR-
/
cells may play an important regulatory role
in human HSV-1 infections.
