T-cell populations specifically depleted of alloreactive potential cannot be induced to lyse H-2-different virus-infected target cells*

Abstract

Mouse lymphocyte populations of one parental H-2 type (A) were specificially depleted of alloreactive potential by filtration through irradiated A X B F1 recipients, and thoracic duct cells were then stimulated with virus in an A X B F1 environment. Experiments using T cells that had previously been exposed to influenza virus in the context of A established that cross-priming for recognition of viral components expressed on H-2-different (B) target cells does not occur. Furthermore, immunologically naive T cells stimulated with vaccinia virus, subsequent to negative selection for reactivity to B, could not be shown to interact with virus-infected cells of type B. Either there is no significa..
