Using the spheroplast fusion technique, we have introduced the cloned E beta b gene into two d haplotype cell lines, the B lymphoma line A20-2J and the macrophage tumor line P388D1. Analysis with a monoclonal antibody indicates that the product of the transfected E beta b gene associates with the endogenous E alpha chain to form an E alpha dE beta b complex. While expression of E alpha dE beta b is constitutive in A20-2J cells transfected with the E beta b gene, surface expression of E alpha dE beta b is detected in transfected macrophage cells only after treatment of cells with culture supernatants from concanavalin A (Con A)-stimulated T cells. Transfected B lymphoma cells and transfected Con A supernatant-treated macrophage cells have acquired the ability to present antigen to E alpha dE beta b-restricted T-cell hybridomas. The observed inducible expression of the transfected gene in the macrophage host indicates that sequences responsible for regulated expression of the E beta b gene may be associated with the transfected gene. In combination with directed mutagenesis, the system described here provides a means to study (i) E beta b sequences that are important in determining the restriction specificity of the E molecule and (ii) sequences associated with the E beta gene that may be important in the regulation of E beta chain expression.
