  • Title: T cells causing immunological disease.
    Author: Zinkernagel RM, Pircher H, Ohashi PS, Hengartner H.
    Journal: Springer Semin Immunopathol; 1992; 14(2):105-13. PubMed ID: 1475738.
    Abstract:
    Evidence is summarized that genetically encoded self peptides may not be considered immunological as self when expressed solely extrathymically on non-lymphohemopoietic cells; nevertheless, they are antigenic and are recognized by induced effector T cells. An immune response is readily induced against such "nonimmunological" self (as against foreign) by an appropriate presentation of these self peptides on proper antigen-presenting cells. If it is substantial, such an immune response causes a disease resembling an autoimmune disease, which is more appropriately called an "immunopathological T cell-mediated disease" rather than a T cell autoimmunity. These pathogenetic considerations may be incorporated into a revised-extended Gell and Coomb's classification of immunopathologies. If this view of immunopathological T cell-mediated diseases against nonimmunological self is correct, such diseases should be amenable to the same prevention (i.e., vaccination) and treatment principles, as are T cell immune responses to foreign antigens.
