Epigenetic silencing of the immunoglobulin heavy-chain gene in classical Hodgkin lymphoma-derived cell lines contributes to the loss of immunoglobulin expression.
Immunoglobulin production is impaired in Hodgkin and Reed-Sternberg (HRS) cells of classical Hodgkin lymphoma (cHL) in spite of functional clonal rearrangements. The presence of "crippling" mutations in coding and regulatory regions, as well as down-regulation of B-cell-specific transcription factors, has been suggested as a potential reason for the lack of immunoglobulin (Ig) chain gene transc...
متن کاملSpecific immunoglobulin cDNA clones produced from hybridoma cell lines and murine spleen fragment cultures by 3SR amplification.
The isothermal 3SR amplification method has been employed to assist in cloning the VL and VH genes from cells of hybridomas and splenic fragment cultures expressing antibodies for phosphorylcholine (PC) and estradiol (E2), respectively. As a first step, pools of degenerate primer pairs were identified complementary to immunoglobulin light and heavy chain variable (V) genes and capable of amplif...
متن کاملMultiple immunoglobulin heavy-chain gene transcripts in Abelson murine leukemia virus-transformed lymphoid cell lines.
Lymphoid cells transformed by Abelson murine leukemia virus (A-MuLV) contain three classes of RNA transcripts from immunoglobulin mu genes. P mu-mRNAs (productive) correspond to the normal 2.7-kilobase (kb) membrane (mu m) and 2.4-kb secreted (mu s) mu mRNA species both in size and coding capacity and occur at approximately equal abundance in most mu-positive (pre-B-like) A-MuLV transformants. ...
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...
متن کاملFunctional 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...
