The purpose of this study was to analyze changes in the T-helper cell 1/T-helper cell 2 (Th1/Th2) balance of peripheral T-helper cells after autologous peripheral blood stem cell transplantation (auto-PBSCT) for non-Hodgkin's lymphoma (NHL) and to evaluate the effects of chemotherapy and granulocyte colony-stimulating factor (G-CSF) on the Th1/Th2 balance. A series of peripheral blood samples from four patients with NHL were collected before peripheral blood stem cell harvest and after auto-PBSCT. Using flow cytometry, Th1 and Th2 cells were identified by their intracellular cytokines: interleukin (IL)-4-/interferon (IFN)-gamma+ and IL-4+/IFN-gamma-, respectively. The Th1/Th2 balance was estimated as the ratio of IL4-/IFN-gamma+ cells to IL-4+/IFN-gamma- cells. Although the Th1/Th2 balance decreased initially, it increased markedly 28 days after the cessation of G-CSF, following auto-PBSCT, in parallel with an increase in lymphocytes. This increase was mainly due to an increase in the proportion of Th1 cells. The Th1/Th2 balance did not change appreciably before PBSC harvest. Serum IFN-gamma increased after auto-PBSCT in three patients. These preliminary data demonstrate that, after auto-PBSCT for NHL, the Th1/Th2 balance decreases initially and then increases after 1 month to levels above pretreatment levels and that the effects of chemotherapy and G-CSF on the Th1/Th2 balance are negligible before PBSC harvest. Further evaluation of the Th1/Th2 balance after allogeneic PBSCT at the single-cell level should be undertaken using this method.

To investigate whether single nucleotide polymorphisms (SNPs) in key cytokine and innate immunity genes influence risk for childhood lymphomas, we genotyped 37 children with Hodgkin's (HL) and 48 with non-Hodgkin's lymphoma (NHL), aged (1 month-14 yr), along with their 85 age- and gender-matched controls suffering from mild medical conditions. Genotypic analysis was performed for 10 SNPs from nine genes with important role in immunoregulatory pathways (IL4, IL4R, IL6, IL10, IL12, IL18, TNFalpha, IFNgamma, CD14). Analysis of SNPs genotypes revealed that the CD14 -159 C>T polymorphism was associated with significantly increased risk for HL regarding both the CC and CT genotypes (OR(CC): 5.36; 95% CI, 1.30-22.14; P = 0.02, OR(CT): 3.76; 95% CI, 1.00-14.16; P = 0.05). An indicative association between IL18-137 G>C polymorphism with the CC genotype and NHL did not reach, however, statistical significance (OR(CC), 3.78; 95% CI, 0.87-16.38; P = 0.08). In conclusion, our findings suggest that genetic variation in the CD14-159 loci may be associated with childhood HL risk; these preliminary findings need to be further confirmed in sizeable multi-centre studies along with determination of cytokines, which could provide an insight on the biologic basis underlying these findings.

Peripheral T cell lymphoma (PTCL) is an aggressive form of non-Hodgkin's lymphoma characterized by a poor prognosis. In this study, we examined the prognostic value of two T-cell-specific transcription factors, GATA3 and T-bet, in PTCL, uncovered the pathogenesis of PTCL, and investigated new PTCL therapeutic targets. Samples from 109 PTCL patients were examined for expression of GATA3, T-bet and CD68. High GATA3 expression correlated with poor survival in PTCL patients and with tumor-associated macrophage (TAM) infiltration, as indicated by the presence of CD68-positive cells. Multivariate analysis further confirmed that high GATA3 expression and Eastern Cooperative Oncology Group (ECOG) scores higher than 2 were independent predictors of patient survival. Using lentiviral transfection to induce stable GATA3 knockdown in a PTCL cell line, we observed that GATA-3 knockdown in Hut78 cells decreased levels of IL4, IL5, IL13 and VEGF mRNA and reduced the number of co-cultured U937 cells that differentiated towards the M2 phenotype. These results suggest that high GATA3 expression is a predictor of a poor prognosis in PTCL, and that T lymphoma cells promote M2-type macrophage differentiation through a GATA3-dependent mechanism.
