Abstract

Severe combined immune deficient (SCID) mice infected orally with reovirus type 1/L die of hepatitis. Leukocytes bearing the cell surface antigens Thy-1.2 and asialoGM-1 (AsGM1) accumulate in the livers of infected animals. These cells display lytic activity toward natural killer-sensitive (YAC-1) and -resistant (P815) cell lines and murine hepatoma line Hepa 1/A1. Although these cells have the capacity to lyse infected hepatoma targets, they cannot clear the virus.
