Autoantibodies play an important role in the pathogenesis of type II collagen-induced arthritis in mice. We have earlier reported a high frequency of cells producing anti-CII autoantibodies and a low frequency of cells producing multispecific antibodies, in regional lymph nodes 9 to 11 days after primary immunization with CII. It is shown here that anti-CII antibodies produced during primary immune response are IgG-antibodies mainly of IgG2a, IgG1 and IgG2b subclasses while IgM antibodies dominate primary responses elicited by OVA and denatured CII as analyzed with a large panel of hybridomas. Anti-CII antibodies generated during the primary response recognize at least five different epitopes on the CII molecule. The specificities of these antibodies for various epitopes result from combinational association of products encoded by genes derived from various VH and VK families and/or by the occurrence of somatic mutations. It is suggested that the primary anti-CII autoantibody response involves activation of memory B cells and is in this aspect different from the origin of "natural" autoantibodies.

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.

D007135 Immunoglobulin Variable Region That region of the immunoglobulin molecule that varies in its amino acid sequence and composition, and comprises the binding site for a specific antigen. It is located at the N-terminus of the Fab fragment of the immunoglobulin. It includes hypervariable regions (COMPLEMENTARITY DETERMINING REGIONS) and framework regions.

D003094 Collagen A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of SKIN; CONNECTIVE TISSUE; and the organic substance of bones (BONE AND BONES) and teeth (TOOTH).

D005803 Genes, Immunoglobulin Genes encoding the different subunits of the IMMUNOGLOBULINS, for example the IMMUNOGLOBULIN LIGHT CHAIN GENES and the IMMUNOGLOBULIN HEAVY CHAIN GENES. The heavy and light immunoglobulin genes are present as gene segments in the germline cells. The completed genes are created when the segments are shuffled and assembled (B-LYMPHOCYTE GENE REARRANGEMENT) during B-LYMPHOCYTE maturation. The gene segments of the human light and heavy chain germline genes are symbolized V (variable), J (joining) and C (constant). The heavy chain germline genes have an additional segment D (diversity).

D005810 Multigene Family A set of genes descended by duplication and variation from some ancestral gene. Such genes may be clustered together on the same chromosome or dispersed on different chromosomes. Examples of multigene families include those that encode the hemoglobins, immunoglobulins, histocompatibility antigens, actins, tubulins, keratins, collagens, heat shock proteins, salivary glue proteins, chorion proteins, cuticle proteins, yolk proteins, and phaseolins, as well as histones, ribosomal RNA, and transfer RNA genes. The latter three are examples of reiterated genes, where hundreds of identical genes are present in a tandem array.
