Popis: We have generated transgenic mouse lineages that express the influenza virus hemagglutinin in different physical forms. One kind expresses the full-length hemagglutinin molecule as a cell surface glycoprotein and can be recognized by hemagglutinin-specific B and T cells. The other expresses a truncated polypeptide corresponding to the N-terminal third of the hemagglutinin molecule. This polypeptide encodes known hemagglutinin-specific T-cell determinants; however, it contains no native B-cell epitopes, since these depend on the conformation of the fully folded protein. In each case, the hemagglutinin transgenic mice display ubiquitous expression of transgenic messenger RNA and induce T-cell tolerance to the transgene-encoded T-cell determinant site 1. Thus, the hemagglutinin is a neo-self-antigen in both kinds of hemagglutinin transgenic mice and should provide a useful system for understanding the factors and mechanisms that govern tolerance and autoimmunity to self-antigens.
