This paper lists the genotype frequencies of 50 polymorphisms of 37 genes (ALDH2, ADRB2, ADRB3, COMT, CD36, CXCR2, CCND1, COX2, CYP2A6, CYP17, CYP19, IGF1, IL-1A, IL-1B, IL-1RN, IL-1R1, IL-6, IL-8, IL-10, LEP, Le, L-myc, MPO, MTR, MTHFR, MAO-A, NQO1, OGG1, p53, p73, Se, SRD5A2, TGF-B, TNF-A, TNF-B, XPD, and XRCC1) and 6 sets of combined genotype frequencies for 241 non-cancer Japanese outpatients. Though the genotype frequencies of 25 polymorphisms have already been reported in our previous papers, 15 polymorphisms (CD36 A52C, CXCR2 C785T, CCND1 G870A, IGF1 C/T at intron 2 and G2502T, IL-1A 46-bp VNTR, IL-1R1 C-116T, IL-6 Ins/Del 17C, IL-8 A-278T and C74T, IL- 10 T-819C, LEP A-2548G, SRD5A2 2-bp VNTR, XPD Lys751Gln, and XRCC1 Arg399Gln) and six sets of combined genotype frequencies (IL-1B C-31T and IL-1A C-889T, IL-1B C-31T and IL-1RN 86-bp VNTR, IL-1B C-31T and IL-1R1 C-116T, TNF-A G-308A and TNF-B A252G, SRD5A2 Val89Leu and 2-bp VNTR, and XRCC1 Arg399Gln and XPD Lys751Gln) were reported in this paper for the first time for Japanese. Although microarray technology will produce this kind of information in near future, this is the first document that reports the genotype/allele frequencies among Japanese for an archival purpose.

Interleukin 10 (IL10) is a powerful Th-2 cell cytokine produced by lymphoid cells that exerts its functions by inhibiting macrophage/monocyte and T-cell lymphocyte replication and secretion of inflammatory cytokines (IL1, TNFA, TGFB, IL6, IL8 and IL12). Genetic association analysis of a well-characterized HBV cohort revealed that one of IL10 haplotypes, IL10-ht2, was strongly associated with hepatocellular carcinoma (HCC) occurrence in gene dose-dependent manner. The frequency of susceptible IL10-ht2 was much higher in HCC patients and significantly increased in order of susceptibility to HBV progression from chronic hepatitis to liver cirrhosis and HCC among hepatitis B patients. In addition, survival analysis clearly showed that the onset age of HCC was also accelerated among chronic hepatitis B patients who were carrying IL10-ht2. Increased IL10 production mediated by IL10-ht2 suggests that up-regulated IL10 accelerates progression of chronic HBV infection, especially to HCC development.

The blood-brain barrier (BBB) mediates interactions between the brain and the cytokines produced in the periphery. Some of these cytokines play significant roles in feeding behavior. This review will summarize various ways by which cytokines cross the BBB and discuss the implications of their transport systems in feeding. For simplicity of discussion, three categories of cytokines are discussed: (1). the proinflammatory cytokines TNFalpha, IFNgamma, IL1, and IL6; (2). the chemokines MIP-1, CINC-1 and IL8; and (3). other cytokines (LIF, CNTF, GM-CSF, FGF, EGF, and TGFalpha). The pharmacokinetics of barrier penetration, compartmental distribution, stability, and mechanism of passage (presence or absence of saturable transport) are summarized. Our understanding of cytokines interacting with the BBB is still growing; not only are more cytokines being studied, but also more details of the nature of the transport systems and how they affect feeding behavior are being explored.

The purpose of this study was to examine the source of adipokines released by the visceral and sc adipose tissues of obese humans. Human adipose tissue incubated in primary culture for 48 h released more prostaglandin E(2), IL-8, and IL-6 than adiponectin, whereas the release of plasminogen activator inhibitor 1 and hepatocyte growth factor was less than that of adiponectin but greater than that of leptin. IL-10 and TNFalpha were released in amounts less than those of leptin, whereas vascular endothelial growth factor and IL1-beta were released in much lower amounts. The accumulation of adipokines was also examined in the three fractions (adipose tissue matrix, isolated stromovascular cells, and adipocytes) obtained by collagenase digestion of adipose tissue. Over 90% of the adipokine release by adipose tissue, except for adiponectin and leptin, could be attributed to nonfat cells. Visceral adipose tissue released greater amounts of vascular endothelial growth factor, IL-6, and plasminogen activator inhibitor 1 compared with abdominal sc tissue. The greatly enhanced total release of TNFalpha, IL-8, and IL-10 by adipose tissue from individuals with a body mass index of 45 compared with 32 was due to nonfat cells. Furthermore, most of the adipokine release by the nonfat cells of adipose tissue was due to cells retained in the tissue matrix after collagenase digestion.

Acute and chronic hyperglycemia are proinflammatory states, but the status of proinflammatory cytokines and markers of oxidative stress and cardiovascular risks is not known in hyperglycemic crises of diabetic ketoacidosis (DKA) and nonketotic hyperglycemia (NKH). We studied 20 lean and 28 obese patients with DKA, 10 patients with NKH, and 12 lean and 12 obese nondiabetic control subjects. We measured 1) proinflammatory cytokines (tumor necrosis factor-alpha, interleukin [IL]-6, IL1-beta, and IL-8), 2) markers of cardiovascular risk (C-reactive protein [CRP], homocysteine, and plasminogen activator inhibitor-1 [PAI-1]), 3) products of reactive oxygen species (ROS; thiobarbituric acid [TBA]-reacting material, and dichlorofluorescein [DCF]), and 4) cortisol, growth hormone (GH), and free fatty acids (FFAs) on admission (before insulin therapy) and after insulin therapy and resolution of hyperglycemia and/or ketoacidosis. Results were compared with lean and obese control subjects. Circulating levels of cytokines, TBA, DCF, PAI-1, FFAs, cortisol, and GH on admission were significantly increased two- to fourfold in patients with hyperglycemic crises compared with control subjects, and they returned to normal levels after insulin treatment and resolution of hyperglycemic crises. Changes in CRP and homocysteine in response to insulin therapy did not reach control levels after resolution of hyperglycemia. We conclude that DKA and NKH are associated with elevation of proinflammatory cytokines, ROS, and cardiovascular risk factors in the absence of obvious infection or cardiovascular pathology. Return of these values to normal levels with insulin therapy demonstrates a robust anti-inflammatory effect of insulin.

The production of proinflammatory cytokines IL-1alpha, IL1 2b, TNF-alpha and IL8 in lachrymal fluid was dynamically determined in 134 patients with uncomplicated and complicated clinical courses of primary (at exacerbation of the cornea) and secondary (with dystrophic changes in the cornea) keratitis. The level of proinflammatory cytokines in lachrymal fluid was found to essentially affect the clinical course in different types of keratitis.

Meningococcal lipopolysaccharide (LPS) is of crucial importance for the pathogenesis of invasive infection. We show that sialylation and elongation of the alpha-chain effectively shields viable unencapsulated Neisseria meningitidis from recognition by human dendritic cells (DC). In contrast, beta- and gamma- chain of the LPS carbohydrate moiety play only a minor role in the interaction with DC. The protective function of the LPS for the bacteria can be counteracted in vivo by phase variation of the lgtA gene encoding LPS glycosyltransferase A. Capsule expression protects N. meningitidis efficiently from recognition and phagocytosis by DC independent of the LPS structure. Despite the significant impact of LPS composition on the adhesion and phagocytosis of N. meningitidis no differences were found in terms of cytokine levels secreted by DC for IL1-beta, IL-6, IL-8, TNF-alpha, IFN-gamma and GM-CSF. However, significantly lower levels of the regulatory mediator IL-10 were induced by encapsulated strains in comparison to isogenic unencapsulated derivatives. IL-10 secretion was shown to depend on phagocytosis because poly alpha-2,8 sialic acid did not influence IL-10 secretion. The use of truncated LPS isoforms in vaccine preparations can therefore not only result in attenuation but also in more efficient targeting of DC.

We reported previously that the core oligosaccharide region of the lipopolysaccharide (LPS) is essential for optimal adhesion of Actinobacillus pleuropneumoniae, an important swine pathogen, to respiratory tract cells. Rough LPS and core LPS mutants of A. pleuropneumoniae serotype 1 were generated by using a mini-Tn10 transposon mutagenesis system. Here we performed a structural analysis of the oligosaccharide region of three core LPS mutants that still produce the same O-antigen by using methylation analyses and mass spectrometry. We also performed a kinetic study of proinflammatory cytokines production such as interleukin (IL)-6, tumor necrosis factor-alpha, IL1-beta, MCP-1, and IL8 by LPS-stimulated porcine alveolar macrophages, which showed that purified LPS of the parent strain, the rough LPS and core LPS mutants, had the same ability to stimulate the production of cytokines. Most interestingly, an in vitro susceptibility test of these LPS mutants to antimicrobial peptides showed that the three core LPS mutants were more susceptible to cationic peptides than both the rough LPS mutant and the wild type parent strain. Furthermore, experimental pig infections with these mutants revealed that the galactose (Gal I) and d,d-heptose (Hep IV) residues present in the outer core of A. pleuropneumoniae serotype 1 LPS are important for adhesion and overall virulence in the natural host, whereas deletion of the terminal GalNAc-Gal II disaccharide had no effect. Our data suggest that an intact core-lipid A region is required for optimal protection of A. pleuropneumoniae against cationic peptides and that deletion of specific residues in the outer LPS core results in the attenuation of the virulence of A. pleuropneumoniae serotype 1.

Calcineurin inhibitors (CIs) cyclosporin and tacrolimus form the basis for immunosuppression in lung transplantation, yet also exert biological effects on nonlymphoid tissue. With the advent of inhaled cyclosporin, we hypothesize that the airway epithelium is also subject to CI effects at high doses. The aim of this study was to identify human tracheobronchial epithelial cell (hTBEC) calcineurin gene expression and quantify effects of CIs on hTBEC growth, interleukin-1-beta stimulated IL-8 production and hTBEC phenotype. Cyclophillin B and FK-associated binding protein, calcineurin A (alpha and beta), and NFATC3 and NFAT5 were detected in hTBEC cultures by RT-PCR. Acute and chronic cyclosporine treatment 1000 ng/mL significantly inhibited hTBEC proliferation, while tacrolimus did not (range of 10 ng/mL to 1000 ng/mL for acute treatment, 50 ng/mL for chronic treatment). Cyclosporin at 10,000 ng/mL significantly increased LDH release by well-differentiated hTBEC cultures (n = 6) and trended towards significance at 1000 ng/mL. IL1-beta stimulated IL-8 production was significantly increased in rapidly growing hTBEC cultures (n = 8) treated with cyclosporin (p = 0.049). Prolonged treatment of well-differentiated hTBECs at air-liquid-interface (ALI) with cyclosporin 1000 ng/mL significantly reduced intact multilayered mucociliary epithelium (p = 0.009). Inhibition of hTBEC growth, stimulation of IL-8 production and long-term effects on mucociliary phenotype and intact multi-layered epithelium suggest that cyclosporin may have a direct toxic effect on airway epithelium after transplantation.

Helicobacter pylori infection is an important risk factor for gastric cancer, but <3% of carriers of this organism will ever develop gastric cancer. Since inflammation plays a significant role in gastric carcinogenesis, it has been suggested that polymorphisms in genes involved in inflammatory response may partly explain why only a subgroup of patients infected with H. pylori develop gastric cancer. We compared relative frequencies of 17 single nucleotide polymorphisms (SNPs) in eight inflammation-related genes between 112 gastric cancer patients and 208 controls. Cases and controls were selected from a large cohort of Finnish male smokers who were recruited into the Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) Study. The studied SNPs were IL-1A (-889 C/T), IL-1B (-511 C/T and -31 T/C), IL-6 (-174 G/C and -597 G/A), IL-8 (-251 T/A, +396 T/G and +781 C/T), IL-8RA (Ex2 +860 G/C), IL-8RB (Exon 3 +1235 T/C, Exon 3 +811 C/T, and Exon 3 +1010 G/A), IL-10 (-819 C/T, -592 C/A, -1082 A/G), and TNF A (-308 G/A, -238 G/A). We found no statistically significant association between any of these SNPs, or the number of pro-inflammatory polymorphisms, with risk of gastric cancer. Our results do not support the hypothesis that polymorphisms in genes involved in the inflammatory response confer differences in gastric cancer risk among different individuals.
