[Immunohistochemical study of intracellular immunoglobulins in the lymph nodes in malignant lymphomas]. 1981

A G Merson, and Iu F Rudens

The immunoperoxidase method was employed to assay the content of immunoglobulins in the lymph node cells in 39 patients with malignant lymphoma. It was found that cytoplasmic immunoglobulins were contained in tumor cells in patients with malignant lymphoma of lymphoplasmacytic/-oid cells (LP immunocytoma) and in some patients with malignant lymphoma of centrofollicular cells and immunoblasts. Only one type of the light chain of immunoglobulins was observed in these cells which points to their monoclonal nature. All cases revealed different amounts of polyclonal plasma cells, containing both chi- and lambda-immunoglobulins, in the affected lymph nodes. Paradoxically large numbers of polyclonal plasma cells were observed in the affected lymph nodes of patients with Mycosis Fungoides and T-cell chronic lymphoid leukosis.

D007128	Immunoglobulin Fragments	Partial immunoglobulin molecules resulting from selective cleavage by proteolytic enzymes or generated through PROTEIN ENGINEERING techniques.	Antibody Fragment,Antibody Fragments,Ig Fragment,Ig Fragments,Immunoglobulin Fragment,Fragment, Antibody,Fragment, Ig,Fragment, Immunoglobulin,Fragments, Antibody,Fragments, Ig,Fragments, Immunoglobulin
D007136	Immunoglobulins	Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.
