Analysis of the repertoire of anti-HLA antibodies with anti-idiotypes to a murine anti-HLA-A2,A28 monoclonal antibody. 1984

C Russo, and M A Pellegrino, and S Ferrone

Xenoantibodies to idiotypes of the anti-HLA-A2,A28 MoAb CR11 -351 were isolated from an antiserum raised in rabbit #81 by immunizations with purified MoAb CR11 -351. The purification procedure involved absorption with insolubilized mouse immunoglobulins and monoclonal antibodies and affinity chromatography on insolubilized MoAb CR11 -351. Two antibody populations were identified in the xenoantibody preparation #81: one recognizes a recurrent idiotope expressed by the MoAb CR10 -215, CR10 -402, Q1/28, Q6 /64, and 6/31 to monomorphic determinants of HLA-A,B antigens and by the MoAb CR10 -343, CR11 -462, and Q5/6 to human Ia antigens. The other antibody population recognizes a private idiotope. Neither idiotope was detected on the anti-HLA-A2,A28 variant (A28) MoAbs BB7 .2, MA2 .2, and PA2.1, on the anti-HLA-A2,B17 MoAb MA2 .1 and on antibody populations in conventional anti-HLA-A2,A28 antisera. The idiotopes were also not detected on the anti-HLA-A2,A28 MoAb A2,A28 M1 which recognizes a determinant spatially close to that identified by the MoAb CR11 -351. The idiotope(s) recognized by the xenoantibodies #81 may be located in the combining site of the MoAb CR11 -351, since its incubation with the anti-idiotype antibodies specifically blocks the reactivity with lymphoid cells with the appropriate HLA phenotype.

UI	MeSH Term	Description	Entries
D007130	Immunoglobulin Idiotypes	Unique genetically-controlled determinants present on ANTIBODIES whose specificity is limited to a single group of proteins (e.g., another antibody molecule or an individual myeloma protein). The idiotype appears to represent the antigenicity of the antigen-binding site of the antibody and to be genetically codetermined with it. The idiotypic determinants have been precisely located to the IMMUNOGLOBULIN VARIABLE REGION of both immunoglobin polypeptide chains.

D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D006680	HLA Antigens	Antigens determined by leukocyte loci found on chromosome 6, the major histocompatibility loci in humans. They are polypeptides or glycoproteins found on most nucleated cells and platelets, determine tissue types for transplantation, and are associated with certain 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.

D015234	HLA-A Antigens	Polymorphic class I human histocompatibility (HLA) surface antigens present on almost all nucleated cells. At least 20 antigens have been identified which are encoded by the A locus of multiple alleles on chromosome 6. They serve as targets for T-cell cytolytic responses and are involved with acceptance or rejection of tissue/organ grafts.	Antigens, HLA-A,HLA-A,Antigens, HLA A,HLA A Antigens
