IL-6, soluble IL-6 receptor (sIL-6R) and soluble gp130 (sgp130) levels were measured in sera and pleural effusions from 42 patients with metastatic carcinoma, non-Hodgkin's lymphoma, tuberculosis, cardiac failure and miscellaneous diseases. Pleural IL-6 levels measured by ELISA were very high in all patient groups (mean 34.8 +/- 15.3 ng/ml) without significant difference according to diseases. IL-6 was shown to be biologically active in a proliferative assay. Serum IL-6 levels were low (0.049 +/- 0.014 ng/ml) and did not correlate with pleural fluid levels. Pleural IL-6 levels correlated with the number of polymorphonuclear cells in pleural fluid (P < 0.03). Pleural sIL-6R levels (76 +/- 8 ng/ml) were always lower than serum levels (196 +/- 12 ng/ml; P < 0.0001) but correlated with them (P < 0.01). Pleural sIL-6R and albumin levels correlated (P < 0.01), suggesting a transudation of sIL-6R from the serum. Pleural sgp130 levels (10.9 +/- 1.0 ng/ml) were lower than serum levels (24.6 +/- 2.8 ng/ml; P < 0.002). After gel filtration of pleural fluid, the bulk of IL-6 (> 90%) was recovered in a 15,000-30,000 fraction, corresponding to the expected mol. wt of free IL-6. These results suggest a production and a sequestration of IL-6 in the pleural cavity in all studied conditions.

Primary effusion lymphoma (PEL) is a new lymphoma entity occurring predominantly, but not exclusively in HIV+ patients with acquired immunodeficiency syndrome (AIDS). PEL grows exclusively in body cavities as serous lymphomatous effusion without evidence of mass disease or dissemination. The cells are infected with the newly discovered human herpesvirus-8 (HHV-8), often accompanied by co-infection with Epstein-Barr virus (EBV). Several lymphoma cell lines have been established from patients with AIDS- and non-AIDS-associated PEL. Given their phenotypical relationship to plasma cells, several cytokines may be important for growth and survival of PEL cells. We investigated the spectrum of cytokines produced by nine HHV-8+ PEL cell lines, in comparison with five Burkitt lymphoma, seven other B non-Hodgkin's lymphoma (B-NHL) and seven multiple myeloma-derived cell lines. In addition, we tested the response of the PEL cells to selected cytokines and the effects of neutralizing anti-cytokine and anti-cytokine receptor antibodies. Using specific ELISAs, PEL cell lines were found to produce large amounts of interleukin-6 (IL-6; 10-5000 pg/ml), IL-6 soluble receptor (IL-6sR; 30-600 pg/ml), IL-10 (600-80,000 pg/ml) and oncostatin M (OSM; 50-80 pg/ml) which in most cases were significantly higher than the levels produced by the Burkitt, B-NHL or myeloma cell lines; on the contrary, PEL cell lines did not elaborate significant levels of macrophage inhibitory protein (MIP-1alpha) and leukemia inhibitory factor (LIF). However, the levels of MIP-1alpha were increased 10- to 100-fold by treatment with phorbol ester TPA. PEL cell lines did not respond proliferatively to IL-6, IL-10, IL-11, LIF, MIP-1alpha, or OSM. Incubation with IL-6sR and IL-6 inhibited cell growth. Anti-IL6 neutralizing antibodies had no effect on PEL cell line proliferation; conversely, whereas anti-IL6R alone inhibited only weakly, anti-gp130 and anti-gp130 plus anti-IL6R showed strong inhibitory effects (>20% inhibition in 5/9 lines and >60% inhibition in 3/9 lines). In summary, PEL cell lines produce high amounts of cytokines (IL-6, IL-10, OSM); proliferation could be inhibited by blocking the receptors of the IL-6 signaling pathway.

Mantle cell lymphoma (MCL) is a non-Hodgkin's lymphoma of B-cell lineage. The blastoid variant of MCL, characterized by high mitotic rate, is clinically more aggressive than common MCL. We used the cDNA array technology to examine the gene expression profiles of both blastoid variant and common MCL. The data was analysed by regression analysis, principal component analysis and the naive Bayes' classifier. Eight genes were identified as differentially deregulated between the two groups. Oncogenes CMYC, BCL2 and PIM1 were upregulated more frequently in the blastoid variant than in common MCL. This implied that the gp130-mediated signal transducer and activator of transcription 3 (STAT3) signalling pathway was involved in the blastoid variant transformation of MCL. Other differentially deregulated genes were TOP1, CD23, CD45, CD70 and NFATC. By using the eight differentially deregulated genes, we created a classifier to distinguish the blastoid variant from common MCL with high accuracy. We also identified 18 genes that were deregulated in both groups. Among them, BCL1, CALLA/CD10 and GRN were suggested to be oncogenes. The products of RGS1, RGS2, ANX2 and CD44H were suggested to promote tumour metastasis. CD66D was suggested to be a tumour suppressor gene.
