Abstract
Targeted cytokine delivery has been gaining popularity in cancer immunotherapy since systemic recombinant cytokine treatment has not been successful due to low response rate and systemic toxicities in the clinical studies. In order to address these issues, we propose a new concept that cytokine signal is specifically activated at tumor-micro-environment (TME) by delivering two protein subunits of heterodimeric cytokine fused with a tumor targeting antibody respectively to TME and by bridging the two subunits into active heterodimeric form.Interleukin-12 (IL-12) is one of the major cytokines which can induce immune activation. IL-12 consists of two protein subunits which are p35 and p40. IL-12 signaling is initiated when it forms as the heterodimeric protein and binds to IL-12 receptor complex. We made fusion proteins of both IL-12p35 and IL-12p40 targeting specific tumor associated antigens (TAAs) and demonstrated the formation of bioactive IL12p70 with TME targeting antibody toward both p35 and p40 to form as the active molecule. We describe our concept validation in an in vitro based functional assay.

Abstract
OBJECTIVE SPI1, also referred to as PU.1, is an Ets family transcription factor that interacts with IRF2, IRF4, and IRF8. In view of the significance of the type I interferon pathway in systemic lupus erythematosus (SLE), this study was undertaken to investigate a possible association between SPI1 polymorphisms and SLE. METHODS A case-control association study was performed using 6 tag single-nucleotide polymorphisms (SNPs), as well as a SNP located upstream of SPI1 previously found to be associated with acute myelogenous leukemia, in 400 Japanese patients with SLE and 450 healthy controls. Resequencing of all exons and known regulatory regions was performed to identify functional polymorphisms. Association of genotype and SPI1 expression was examined using the GENEVAR database and reporter assays. RESULTS A significant association was detected in 2 SNPs in intron 2 (rs10769258 and rs4752829) (P = 0.005 and P = 0.008, respectively, under the dominant model). The association was stronger in patients with nephropathy. Resequencing identified a potentially functional polymorphism in the 3'-untranslated region (3'-UTR), rs1057233, which was in strong linkage disequilibrium with the SNPs in intron 2. The number of risk alleles at rs1057233 was strongly correlated with SPI1 messenger RNA (mRNA) level in the database analysis (P = 0.0002), and was confirmed by a reporter assay. Interestingly, rs1057233 alters a target sequence for microRNA hsa-miR-569 (miR-569). Transfection experiments demonstrated that miR-569 inhibits expression of a reporter construct with the 3'-UTR sequence containing the nonrisk allele but not the risk allele. CONCLUSION Our findings indicate that a SNP in the 3'-UTR of SPI1 is associated with elevated SPI1 mRNA level and with susceptibility to SLE.

Abstract
Introduction Recent studies identified STAT4 (signal transducers and activators of transcription-4) as a susceptibility gene for systemic lupus erythematosus (SLE). STAT1 is encoded adjacently to STAT4 on 2q32.2-q32.3, upregulated in peripheral blood mononuclear cells from SLE patients, and functionally relevant to SLE. This study was conducted to test whether STAT4 is associated with SLE in a Japanese population also, to identify the risk haplotype, and to examine the potential genetic contribution of STAT1. To accomplish these aims, we carried out a comprehensive association analysis of 52 tag single nucleotide polymorphisms (SNPs) encompassing the STAT1-STAT4 region. Methods In the first screening, 52 tag SNPs were selected based on HapMap Phase II JPT (Japanese in Tokyo, Japan) data, and case-control association analysis was carried out on 105 Japanese female patients with SLE and 102 female controls. For associated SNPs, additional cases and controls were genotyped and association was analyzed using 308 SLE patients and 306 controls. Estimation of haplotype frequencies and an association study using the permutation test were performed with Haploview version 4.0 software. Population attributable risk percentage was estimated to compare the epidemiological significance of the risk genotype among populations. Results In the first screening, rs7574865, rs11889341, and rs10168266 in STAT4 were most significantly associated (P < 0.01). Significant association was not observed for STAT1. Subsequent association studies of the three SNPs using 308 SLE patients and 306 controls confirmed a strong association of the rs7574865T allele (SLE patients: 46.3%, controls: 33.5%, P = 4.9 × 10-6, odds ratio 1.71) as well as TTT haplotype (rs10168266/rs11889341/rs7574865) (P = 1.5 × 10-6). The association was stronger in subgroups of SLE with nephritis and anti-double-stranded DNA antibodies. Population attributable risk percentage was estimated to be higher in the Japanese population (40.2%) than in Americans of European descent (19.5%). Conclusions The same STAT4 risk allele is associated with SLE in Caucasian and Japanese populations. Evidence for a role of STAT1 in genetic susceptibility to SLE was not detected. The contribution of STAT4 for the genetic background of SLE may be greater in the Japanese population than in Americans of European descent.

Abstract
OBJECTIVE To determine whether the IRF5 gene, which encodes interferon regulatory factor 5, is associated with systemic lupus erythematosus (SLE) in a Japanese population. METHODS A case-control study was performed in 277 SLE patients and 201 healthy controls. Associations between the IRF5 genotype and levels of messenger RNA (mRNA) for interferon (IFN) pathway genes were examined using an mRNA expression database of HapMap samples. RESULTS Carriers of the rs2004640T single-nucleotide polymorphism (SNP) were slightly increased among SLE patients (58.8%) as compared with controls (50.2%). When data from our Japanese population were combined with previously published data from a Korean population, the T allele frequency was found to be significantly increased in SLE patients (P = 8.3 x 10(-5)). While no association was observed for the rs10954213 SNP or the exon 6 insertion/deletion, significant associations with 3 intron 1 SNPs (-4001, rs6953165, and rs41298401) were found. The allele frequency of rs41298401G was significantly decreased in SLE patients (13.0% versus 18.7% in controls; P = 0.017), and the allele frequency of rs6953165G, which was in absolute linkage disequilibrium with -4001A, was increased in SLE patients (8.8% versus 5.2% in controls; P = 0.034). The Caucasian risk haplotype was not present; instead, a protective haplotype carrying rs2004640G, rs41298401G, the deletion in exon 6, and rs10954213A was identified. SNP rs10954213, but not intron 1 SNPs, was associated with IRF5 at the mRNA level; nevertheless, intron 1 SNPs were also associated with levels of mRNA for several IFN pathway genes, suggesting a functional role. CONCLUSION IRF5 was found to be associated with SLE in Asian populations. Intron 1 SNPs, rather than exon 6 and 3'-untranslated region polymorphisms, appeared to play a crucial role.

Abstract
Human NKG2A, NKG2C and NKG2E genes are located on 12p13 in the NK gene complex. We recently identified deletion of NKG2C in a Japanese population. This study was performed to identify the breakpoint, and to examine the association of NKG2C deletion with susceptibility to rheumatoid arthritis and systemic lupus erythematosus. The location of the breakpoint was determined to be 1.5-1.8 kb telomeric from the 3' end of NKG2A by comparing sequences of the intergenic segments upstream and downstream of the NKG2C gene in the common haplotype with the intergenic sequence between NKG2A and NKG2E in the deletion haplotype. Based on this information, a genotyping system was developed. The frequency of NKG2C deletion haplotype was 20.2% in Japanese and 20.0% in Dutch populations. The frequency of homozygous deletion was 4.1% in Japanese and 3.8% in Dutch. Evidence for an association with rheumatic diseases was not detected. These results indicated that NKG2C deletion is commonly present in Japanese and Dutch, suggesting that NKG2C is not essential for survival and reproduction, and is not associated with rheumatic diseases.

Abstract
CD94 and NKG2 are members of the NK cell receptor families, and are encoded in the natural killer gene complex (NKC) on human chromosome 12p12-13, one of the candidate chromosomal regions for rheumatic diseases. To examine a possible association between variations in CD94 and NKG2 genes and genetic susceptibility to rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), we carried out a systematic polymorphism screening of NKG2-A (KLRC1), NKG2-C (KLRC2) and CD94 (KLRD1) genes on a population basis. In NKG2-A, previously considered to be highly conserved, 10 polymorphisms in the noncoding region and introns, as well as one rare variation leading to an amino acid substitution within the transmembrane region, c.238T>A (Cys80Ser), were detected. In NKG2-C, in addition to the previously described two nonsynonymous substitutions, c.5G>A (Ser2Asn) and c.305C>T (Ser102Phe), two polymorphisms were newly detected in the noncoding region. In CD94, only one single nucleotide substitution was identified in the 5' untranslated region. When the patients and healthy individuals were genotyped for these variations, no significant association was observed. However, although statistically not significant, NKG2-A c.238T>A (Cys80Ser) was observed in three patients with RA, but in none of the healthy individuals and the patients with SLE. Unexpectedly, in the process of polymorphism screening, we identified homozygous deletion of NKG2-C in approximately 4.3% of healthy donors; under the assumption of Hardy-Weinberg equilibrium, the allele frequency of NKG2-C deletion was estimated to be 20.7%. These results demonstrated that, although human NKG2-A, -C and CD94 are generally conserved with respect to amino acid sequences, NKG2-A is polymorphic in the noncoding region, and that the number of genes encoded in the human NKC is variable among individuals, as previously shown for the leukocyte receptor complex (LRC), HLA and Fcgamma receptor (FCGR) regions.

Abstract
We found three new variations in the OX40 ligand (OX40L, CD134L) gene and its 5' upstream region. -921 (G-->A) at 5' upstream region, -19 (C-->G) at 5' untranslated region, and 202 + 25 (G-->T) at intron 2 were identified. -921 (G-->A) and 202 + 25 (G-->T) were detected in a substantial proportion of healthy Japanese individuals and were considered to be single nucleotide polymorphisms (SNPs). -19 (C-->G) was detected in only one healthy individual. There was no association between these variations and the presence of rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE).

Abstract
In Experiment 1, 3 mother-child pairs of Japanese monkeys (Macaca fuscata) were given simultaneous choice tests between raisins and popcorn. The mothers and offspring showed different choice patterns. Cofeeding opportunities were then alternated with individual choice tests. In Experiment 2,2 other pairs were added. Each animal was again offered simultaneous choice tests between marshmallows and almonds. Food aversion conditioning was used to create different choice patterns for mothers and offspring. After cofeeding and choice tests, the differences in choice patterns disappeared in both experiments. The changes after contact with the other's eating pattern during cofeeding was as follows: foods consumed by either came to be eaten by both; foods consumed by both continued to be eaten by both; and foods consumed by neither continued to be ignored. The results provide evidence for social transmission of food preferences in this species.
