Appearanc of cytotoxic cells within the bronchus after local infection with herpes simplex virus.
Cells from rabbit spleens, bronchial washings (BW) and bronchus-associated lymphoid tissues (BALT) were examined for their ability to lyse cells infected with herpes simplex virus (HSV). Specific lysis of HSV-infected cells was mediated by BW cells as early as 4 days after intratracheal infection of the rabbits with the virus whereas lysis by spleen cells and BALT cells was not detected until 7 or more days after infection. Lysis by spleen cells was initially detected 7 days after intraperitoneal injection of the virus but lysis by BW and BALT cells was not observed until 14 days after infection. Although spleen, BW, and BALT cells could lyse antibody-coated target cells, antibodies detectable by antibody-dependent cellular cytotoxicity could not be detected in bronchial washings until 7 or more days after infection. The data suggest that cells capable of direct cytotoxicity of virus-infected cells appear within the bronchus after local infection by the virus.
