Cell receptors for the mammalian reovirus. I. Syngeneic monoclonal anti-idiotypic antibody identifies a cell surface receptor for reovirus.
We have prepared and characterized a syngeneic monoclonal anti-idiotype directed against the idiotype (Id3) of the anti-reovirus type 3 hemagglutinin B cell hybridoma 9BG5. We have shown this monoclonal antibody to be anti-idiotypic in a series of inhibition studies with purified sigma 1 (hemagglutinin) protein and with absorption studies on the idiotypic R1.1 cell line. That the idiotype Id 3 defined by the monoclonal anti-idiotype is distinct from H-2 was demonstrated by its presence on an idiotype-expressing H-2 negative cell line (R1.E). Binding of the anti-idiotype is relatively tunicamycin resistant and pronase/trypsin sensitive, which suggests that the recognition site of the anti-idiotypic receptor is poorly glycosylated. The presence of idiotype-like receptors on reovirus type 3 susceptible neurons may have important implications for the presence of related gene families between neural and lymphoid tissue. The implications of recognition by neuronal cells of an anti-idiotypic monoclonal antibody directed against the reovirus 3 attachment receptor for the pathogenesis of viral-induced auto-immunity are discussed.
