Cirrhotic hyperglobulinemia: increased rates of immunoglobulin synthesis by circulating lymphoid cells. 1979

S R Berger, and R A Helms, and D M Bull

We have measured immunoglobulin (Ig) synthesis by circulating lymphoid cells of 20 patients with cirrhotic hyperglobulinemia (CH) and 20 age-matched controls. We used specific anti-Ig antisera to precipitate Ig synthesized from [14C] amino acid precursors in 13 controls and employed an electroimmunoassay of the "rocket" type to measure Ig elaborated by cultured cells in 4 patient-control pairs. In addition, we studied 3 patient-control pairs by absorption of elaborated Ig onto an anti-Ig-coated solid phase, bromoacetylcellulose. The synthetic index (SI; the ratio of Ig synthesis by a CH patient and a control) was elevated in every case. Mean SI by coprecipitation was 7.2 +/- 5.4 (mean +/- SD), by rocket" 7.3 +/- 3.0 for IgG and 2.2 +/- 0.8 for IgA, and by immunoabsorption 13.8 +/- 8.4 for IgG. Three cirrhotic nonhyperglobulinemic patient-control pairs showed a mean SI of 1.0 +/- 0.1. CH and control populations showed equal numbers of membrane Ig-positive B lymphocytes by immunofluorescence. We conclude that (1) peripheral blood lymphoid cells are appropriate for study of differences in Ig synthetic capacity among individuals; (2) CH is associated with increased in vitro Ig synthesis; and (3) CH lymphocytes may be an appropriate cell population for the study of control mechanisms in Ig synthesis.

UI	MeSH Term	Description	Entries
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.

D011947	Receptors, Antigen, B-Cell	IMMUNOGLOBULINS on the surface of B-LYMPHOCYTES. Their MESSENGER RNA contains an EXON with a membrane spanning sequence, producing immunoglobulins in the form of type I transmembrane proteins as opposed to secreted immunoglobulins (ANTIBODIES) which do not contain the membrane spanning segment.
