title: Antigen-specific. I region-restricted interactions in vitro between tumor cell lines and T cell hybridomas.
abstract: A series of H-2d B cell tumor lines and one monocytic tumor cell line were shown to be capable of I region-restricted antigen presentation to I-A-d- and I-Ed- restricted, antigen-specific cloned T cell hybridomas. For the most part, antigen presentation correlated with the present of Ia antigens on the presenting cells, although in a few interesting cases Ia-expression lines failed to present antigen. These T cell hybridomas, together with the B cell and to monocyte tumor cell lines, offer a unique set of tools to study the phenomenon of I region-restricted antigen presentation.
