title: Elicitation of anti-H-2 cytotoxic T lymphocytes with antigen-modified H-2 negative stimulator cells.
abstract: By a newly developed technique, we have modified H-2k-negative cells in such a way as to render them capable of elicitation of anti-H-2 CTL. Purified H-2Kk and/or partially purified Iak glycoproteins were incorporated into lipid vesicles that contained the hemagglutinin-neuraminidase (HN) glycoprotein and the fusion (F) glycoprotein of Sendai virus. These lipid vesicles were incubated with H-2-negative tumor cells (R1-) in a manner that resulted in rendering these cells capable of eliciting anti-H-2Kk CTL. The presence of Iak on the surface of the modified stimulator cell had a significant effect on the proportion of anti-H-2Kk CTL possessing a particular Lyt phenotype. Primary effector cells elicited by an H-2Kk-Iak difference were primarily Lyt 1-, 2+, whereas primary anti-H-2Kk CTL elicited by an H-2Kk difference alone were predominantly Lyt 1+, 2+.
