Schizophrenia has been observed to be associated with various abnormalities in cytokines and cytokine receptors. Three very recent reports showed the evidence that the IL3 gene, colony stimulating factor 2 receptor alpha (CSF2RA), beta (CSF2RB) and IL-3 receptor alpha (IL3RA), the IL-specific receptor sub-units for CSF2 and IL3, respectively, are associated with schizophrenia. To examine the association of the IBRA polymorphism (rs6603272) with schizophrenia in a Chinese population, 310 physically healthy patients with schizophrenia were compared with 330 age-, sex-matched normal controls. Statistically significant differences were observed in both allelic and genotypic frequencies of the rs6603272 polymorphism (Allele, chi(2) = 6.24, d.f. = 1, p =0.013, odds ratio (OR)= 1.35, 95% Cl 1.07-1.71; Genotype, chi(2) = 6.85, d.f. = 2, p = 0.033). Our results indicate a small but significant contribution of the IBRA polymorphism to susceptibility to schizophrenia, suggesting that the IL3 pathway may be involved in schizophrenia.

Follicular lymphoma (FL) is a germinal center-derived B-cell lymphoma that is known to proliferate in the intrafollicular region. However, lymphoma cells can be identified in the extrafollicular regions, which are related to disease dissemination. We purified the intrafollicular and extrafollicular regions of FL cells by laser microdissection and conducted microarray analysis in order to characterize the gene expression profiles of FL cells from both regions. BCL2 and genes of germinal B-cell markers clearly separated intrafollicular and extrafollicular regions of reactive follicular hyperplasia, suggesting the adequacy of the current analysis. In FL cases, cytokine-related genes were significantly enriched in extrafollicular regions compared with those in the intrafollicular regions. In intrafollicular regions of FL, cell-cycle-related genes were enriched. We found that the FL cells in the extrafollicular region more strongly expressed IL3RA and CXCL12 than those of intrafollicular regions. The cytokines might be also derived from stroma cells in the extrafollicular regions, which may initiate activation and migration of the tumor cells to this region. Our results suggest that FL cell interaction with surrounding stroma cells plays an important role in the pathophysiology of FL and that such interactions should be a good target for therapy.
