title: Association between H-2 and vaccinia virus-induced antigens on the surface of infected cells.
abstract: The relationship between H-2 molecules and vaccinia virus-induced antigens on the surface of H-2d infected cells was investigated by the differential redistribution method and by the blocking capacity of monospecific anti-H-2 sera on an anti-vaccinia cell-mediated cytotoxicity (CMC). Capping of either H-2K or H-2D molecules upon addition of monospecific and anti-H-2 sera was followed by the complete redistribution of viral antigens, suggesting the formation, on the cel membrane, of complexes of H-2K, H-2D molecules and vaccinia virus-induced antigens. However, not all H-2 molecules were involved in this association since i) free H-2K and H-2D molecules still moved independently on the cell surface, and ii) capping of vaccinia virus-induced antigens failed to induce the redistribution of all the H-2K and H-2D molecules. In addition, either monospecific anti-H-2K or anti-H-2D antiserum was found to exert potent blocking activity on anti-vaccinia CMC, indicating also a close topographical relationship between H-2K, H-2D molecules and vaccinia virus-induced antigens.
