CBA/H mice produced serum anti-pig IgG1, IgG2a, and IgG2b following xenotransplantation of pig proislets beneath the kidney capsule; anti-pig IgM was present as pre-existing antibody in the serum of normal CBA/H mice and was also produced in response to pig proislet xenografts. Serum anti-pig IgG3 was not detected post-xenotransplantation. Rejection of pig proislet xenografts and the production of anti-pig IgG1, IgG2a, and IgG2b isotypes were CD4 T cell-dependent. The capacity for adoptively transferred hyperimmune CBA/H mouse anti-pig PBL serum to induce the rejection of intact pig proislet xenografts in CD4 T cell-depleted mice was dose dependent and correlated with markedly elevated levels of serum anti-pig IgG3. Levels of anti-pig IgG1, IgG2a, IgG2b, and IgM comparable to control mice acutely rejecting pig proislet xenografts and achieved following adoptive transfer of hyperimmune serum did not correlate with induced xenograft rejection. These findings suggest that anti-pig Ig isotypes produced during the conventional process of acute proislet xenograft rejection do not play a major role in mediating graft damage. The acute rejection of pig proislet xenografts in the absence of serum anti-pig Ig in microMT-/- hosts confirmed that anti-pig antibody is not essential for proislet xenograft destruction.

D007132 Immunoglobulin Isotypes The classes of immunoglobulins found in any species of animal. In man there are nine classes that migrate in five different groups in electrophoresis; they each consist of two light and two heavy protein chains, and each group has distinguishing structural and functional properties.

D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D000910 Antibodies, Heterophile Antibodies elicited in a different species from which the antigen originated. These antibodies are directed against a wide variety of interspecies-specific antigens, the best known of which are Forssman, Hanganutziu-Deicher (H-D), and Paul-Bunnell (P-B). Incidence of antibodies to these antigens--i.e., the phenomenon of heterophile antibody response--is useful in the serodiagnosis, pathogenesis, and prognosis of infection and latent infectious states as well as in cancer classification.
