Functional Immunoglobulin Light Chain Genes
Rearrangement of Ig genes proceeds during B cell differentiation in an orderly fashion. First the heavy (H) chain gene is rearranged in pre-B cells . These cells can express cytoplasmic A chain but no light (L) chain (1). The K light chain genes rear range next and if they fail to produce a functional gene on either chromosome the X light chain genes are rearranged (2) . It is generally believe...
متن کاملThe requirement of light chain for the surface deposition of the heavy chain of immunoglobulin M.
The murine tumor line 70Z/3 resembles a pre-B lymphocyte in containing the heavy chain of IgM (mu) as a cytoplasmic protein in the apparent absence of light chain (L). However, these cells can be induced by lipopolysaccharide to differentiate into a B lymphocyte-like state, containing mu2L2 tetramers as membrane-bound molecules. This is a accompanied by an increase in mu synthesis, the acquisit...
متن کاملOrganization of immunoglobulin heavy chain genes and allelic deletion model.
We have assessed the number of times the gene sequence encoding constant regions of mouse immunoglobulin heavy chains gamma1, gamma2a, and gamma3 are represented in the mouse genome by hybridization kinetic analysis. All three genes are present at one copy each per haploid genome in normal tissues and myelomas producing IgM or IgG3. IgG1-producing myelomas, however, contain 1 copy each of the g...
متن کاملImmunoglobulin heavy and light chain isotypes in multiple myeloma patients.
The frequency of expression of immunoglobulin (Ig) light and heavy chain isotypes was analyzed in myeloma proteins (M-proteins) from sera of 40 Indian patients with clinically established multiple myeloma. Patients samples were screened by a combination of electrophoresis, immunoelectrophoresis (IEP) and ELISA techniques in this study. We found that majority of the myeloma proteins (58%) were o...
متن کاملAn Immunoglobulin Light Chain
Identification of the immunogens responsible for the production of pathogenic autoantibodies is a major problem in the field of autoimmunity. In the principal diseases that are thought to involve autoimmunization, rheumatoid arthritis, type I diabetes, and multiple sclerosis are examples, the instigating stimulus is unknown. Another example of the gap in our knowledge of disease-causing immunog...
