Abstract

In order to determine the influence of dialysis membranes on immunoglobulin (Ig) and interleukin-6 (IL-6) production, peripheral blood mononuclear cells (PBMC) from 11 haemodialysis patients were cultured for 7 days on Cuprophan, Hemophan, and polyacrylonitrile flat-sheet dialysis membranes. IL-6, IgG, IgA, and IgM were assayed in the supernatants using ELISA. Pokeweed-mitogen-stimulated IgG production declined significantly from 319 +/- 40 ng/ml on polystyrole to 162 +/- 26 ng/ml on Cuprophan, 135 +/- 25 ng/ml on Hemophan, and 109 +/- 20 ng/ml on polyacrylonitrile. A similar pattern was observed for IgA production by PBMC. In comparison to polystyrole (724 +/- 34 pg/ml), IL-6 production by PBMC was significantly reduced in the presence of Cuprophan (151 +/- 45 pg/ml), Hemophan (167 +/- 6 pg/ml) and polyacrylonitrile (108 +/- 33 pg/ml). The fact that the level of monocyte-derived IL-6, a stimulator of B cells, was decreased suggests that reduced B cell activity may be due to diminished stimulation by monocytes.

A mutation generating a stop codon in the alpha-L-fucosidase gene of a fucosidosis patient.

Fucosidosis is an autosomal recessive, lysosomal storage disease featured by deficient activity of alpha-L-fucosidase. Lymphoid cell lines from a fucosidosis patient (JT) and a healthy individual (control) contained alpha-L-fucosidase mRNA of the same size, 2.3 Kb, as determined by Northern blot analysis. cDNA was prepared from alpha-L-fucosidase mRNA of JT and control cells and each cDNA was amplified by the polymerase chain reaction. Direct DNA sequencing of the amplified products revealed a single mutation in JT, a G1141-->T transition. This changed the codon (GAA) for Glu-375 to a stop codon (UAA). Amplification and sequencing of the area containing the G1141-->T transition in genomic DNA of JT and control cells demonstrated that the mutation was homozygous in JT. Analysis of cDNA and genomic DNA derived from lymphoid cells of mother JT revealed her to be heterozygous (G and T) at position 1141. The G1141-->T mutation is probably responsible for disease in JT.

Transcription of the tumor necrosis factor alpha gene is rapidly induced by anti-immunoglobulin and blocked by cyclosporin A and FK506 in human B cells.

The human tumor necrosis factor alpha (TNF-alpha) gene encodes a cytokine whose activities have been implicated in many immunopathological processes, including the activation and differentiation of lymphocytes. Originally identified as a monocyte factor, our studies and those of others have demonstrated that B and T lymphocytes produce TNF-alpha when stimulated by a variety of inducers. We report here that TNF-alpha gene transcription is rapidly and highly induced in three independently derived human Burkitt lymphoma cell lines, as well as in freshly isolated human splenic B cells, activated by antibodies to surface immunoglobulin. This burst in TNF-alpha gene transcription is associated with an induction of TNF-alpha bioactivity in the culture supernatants from stimulated splenic B cells. Moreover, induction of TNF-alpha gene transcription by anti-immunoglobulin was blocked by the immunosuppressants cyclosporin A and FK506. These studies demonstrate that TNF-alpha production is an early event in B-cell activation and they establish the efficacy of using immunosuppressants as probes in dissecting transcriptional activation pathways in human B cells.

Epstein-Barr virus-transformed B lymphocytes produce low molecular mass molecules with autocrine growth factor and competence factor activity.

A human Epstein-Barr virus (EBV)-positive lymphoblastoid B cell line, named BA-D10-4, produces a factor of a molecular mass less than 10 kDa that promotes cell proliferation of both BA-D10-4 cells and other human T or B lymphoid cell lines, either EBV-positive or -negative. The factor synergizes with higher molecular mass autocrine growth factors and makes both BA-D10-4 cells and B cell lines from Burkitt's lymphoma, but not cells from T cell leukemia, more responsive to interleukin-1 and interleukin-6. Therefore, this low molecular mass factor seems to be an autocrine growth factor per se and to have the characteristics of a competence factor.
