Interleukin-1B and IL-1 receptor antagonist gene polymorphisms are associated with an increased risk of gastric cancer (GC) in Caucasian populations. However, recent studies could not find any association between IL-1B-511T polymorphism and the risk of GC in Asians. We tested for an association between IL-1 loci polymorphisms with increased gastric mucosal levels of IL-1β and an increased risk of developing GC in a Korean population. Polymorphisms of IL-1A-889, IL-1B-31, IL-1B-511 and IL-1RN were genotyped in 434 controls and 234 patients with GC. Mucosal IL-1β cytokine was measured using an ELISA. The frequencies of IL-1A, IL-1B-511, IL-1B-31 and IL-1RN were not statistically different between controls and all patients with GC. After subclassification of GC, only patients with intestinal-type GC showed a higher frequency of IL-1B-31T homozygotes (OR = 2.2; 95% CI = 1.1-4.3) compared with controls. Risk was also significantly increased in these patients for IL-1B-31T homozygotes compared with patients with diffuse-type GC (OR = 3.4; 95% CI = 1.5-7.7). As in Caucasian populations, linkage disequilibrium between IL-1B-31 and IL-1B-511 was nearly complete, but the pattern of haplotype related to the risk of GC (IL-1B-31T/IL-1B-511C) was opposite (IL-1B-511T/IL-1B-31C). Mucosal IL-1β levels in H. pylori-infected GC patients were higher in patients homozygous for IL-1B-31T compared with IL-1B-31C/T and IL-1B-31C/C. Thus, the combined effects of H. pylori infection and IL-1B-31T/IL-1B-511C polymorphisms with enhanced mucosal IL-1β production contributed to the development of intestinal-type GC in this Korean population.

<P>T cell stimulation via glucocorticoid-induced tumor necrosis factor receptor (TNFR)-related protein (GITR) elicits antitumor activity in various tumor models; however, the underlying mechanism of action remains unclear. Here we demonstrate a crucial role for interleukin (IL)-9 in antitumor immunity generated by the GITR agonistic antibody DTA-1. IL-4 receptor knockout (Il4ra(-/-)) mice, which have reduced expression of IL-9, were resistant to tumor growth inhibition by DTA-1. Notably, neutralization of IL-9 considerably impaired tumor rejection induced by DTA-1. In particular, DTA-1-induced IL-9 promoted tumor-specific cytotoxic T lymphocyte (CTL) responses by enhancing the function of dendritic cells in vivo. Furthermore, GITR signaling enhanced the differentiation of IL-9-producing CD4(+) T-helper (T(H)9) cells in a TNFR-associated factor 6 (TRAF6)- and NF-kappa B-dependent manner and inhibited the generation of induced regulatory T cells in vitro. Our findings demonstrate that GITR co-stimulation mediates antitumor immunity by promoting T(H)9 cell differentiation and enhancing CTL responses and thus provide a mechanism of action for GITR agonist-mediated cancer immunotherapies.</P>

Early Phase of UVB - induced GM - CSF Upregulation in Epithelial Cell Line is not Totally Dependent on IL - 1α

Park, Kyoung Chan,Kim, Kyu Han,Ahn, Jong Seong,Chung, Jin Ho,Youn, Jai Il,Whang, Ji Hwan,Youn, Sang Woong,Kim, Young Gull,Koh, Woo Seok,Jung, Hyun Chae 대한피부과학회 1997 Annals of Dermatology Vol.9 No.4

Backgrounds : It was demonstrated that ultraviolet(UV) B light induces the release of IL-la in cultured human epithelial cell line and augmentation of GM-CSF production by UVB is reported to be mediated by IL-1α in the murine keratinocyte cell line Pam 212. Objective : The purpose of this study was to evaluate the effects of UVB on kinetic profile of IL-1 and GM-CSF mRNA expression and to see whether synthesis of GM-CSF by UVB can be completely inhibited by blocking IL-1α mediated pathway. Method : We used a competitive RT-PCR for measuring cytokine gene expression in epithelial cell line after UV radiation. Results : The IL-1α mRNA increased as early as 1h after UV irradiation, and then decreased at 3h after the irradiation. Thereafter, the response of IL-1α mRNA was upregulated with a second peak at 6h after the UV irradiation. However, mRNA for GM-CSF increased at 1h after UV light exposure and anti-IL-1α antibodies could only partially inhibit UV-augmented GMCSF production. Conclusion : UVB induced GM-CSF production seemed to be mainly mediated by UVB induced IL-1α but these results suggest that UVB may also induce GM-CSF production through an IL-1α independent pathway.

Huma Keratinocytes are capable of producing a wide variety of cytokines and growth factors that may act as mediator in an immune response and play an important role in proliferation and repair. Production of epidermal cytokines may be induced by bacterial products, by other proinflammatory cytokines, or by physical alteration including ultraviolet radiation. In the present study, we investigated the effect of UVA and PUVA on the production of IL-6 by cultured human keratinocyte. Human keratinocytes derived from normal foreskin were treated with various dose of UVB, UVA and PUVA. With the irradiated keratinocytes or culture supernatant we measured the expression of IL-6 mRNA and the production of IL-6. The result of - the present study was that the UVB increased the production of IL-6 but UVA and PUVA didn't increase the production of IL-6 by human keratinocyte.

A genome-wide by PM₁₀ interaction study identifies novel loci for lung function near <i>BICD1</i> and <i>IL1RN-IL1F10</i> genes in Korean adults

Kim, Hyun-Jin,Seo, Yong-Seok,Sung, Joohon,Chae, Jeesoo,Yun, Jae Moon,Kwon, Hyuktae,Cho, Belong,Kim, Jong-Il,Park, Jin-Ho Elsevier 2020 CHEMOSPHERE - Vol.245 No.-

<P><B>Abstract</B></P> <P>Although several genome-wide interaction studies (GWIS) have been performed in specific European populations to understand the missing link between genetic and environmental factors for lung function, GWIS of Asian samples remain rare. Therefore, we performed a GWIS of exposure to air pollution to identify loci for lung function in Korean adult men. A total of 1826 adult men recruited from two health check-up centers were included in the analysis and the annual mean concentrations of ambient particulate matter with an aerodynamic diameter ≤10 μm (PM<SUB>10</SUB>) were used. In case of forced vital capacity (FVC), one SNP (rs12312730) that passed our genome-wide threshold of <I>p</I>int < 1 × 10–5 was detected in the intronic region of the <I>BICD1</I> gene on chromosome 12. In addition, we found two variants (rs6743376 and rs17042888) located near the <I>IL1RN-IL1F10</I> gene that were involved in the inflammatory response and associated with decreased FVC via interaction with PM<SUB>10</SUB> exposure. A stratified association analysis according to these SNP genotypes showed that PM<SUB>10</SUB> concentrations in subjects with one or two of the risk alleles, compared with those with the non-risk allele, were significantly correlated with a reduction in FVC. This pattern was replicated in another 892 Korean adult samples. The current study reports the first GWIS discovery in an Asian population: the <I>BICD1</I> and <I>IL1RN-IL1F10</I> genes may contribute to the decrease in FVC levels by interacting with PM<SUB>10</SUB> exposure.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Significant interactions between <I>BICD1 or IL1RN-IL1F10</I> and PM<SUB>10</SUB> for FVC were found. </LI> <LI> The several SNPs in these genes were more susceptible to FVC decline by PM<SUB>10</SUB>. </LI> <LI> For FVC, these interaction effects were reproducible in another sample. </LI> </UL> </P>

Objective: To investigate the expression pattern of transforming growth factor-β-inducible gene-h3 (βig-h3) within rheumatoid synovial tissue and the regulation of βig-h3 synthesis in fibroblast-like synoviocyte (FLS). Methods: Synovial tissues obtained from patients with rheumatoid arthritis and osteoarthritis were obtained during joint replacement surgery. βig-h3 expression was evaluated with immunohistochemical stain. FLS was isolated from synovial tissues and stimulated with cytokines including TGF-β, TNF-α, IL-1β, IFN-γ, IL-6, IL-4, and IL-10. βig-h3 synthesis was measured using semiquantitative RT-PCR, ELISA, immunofluorescence stain, and flow cytometry. Results: Expression of βig-h3 was diffuse and abundant in both lining and sublining layers of rheumatoid synovium, which was more prominent than those of osteoarthritis. Production of βig-h3 in FLS was regulated by TGF-β1 in a dose-dependent manner and was highest at 5 ng/mL of TGF-β1. TNF-α and IL-1β upregulated the production of βig-h3 from FLS synergistically with TGF-β1 but other cytokines such as IL-4, IL-6, IL-10 did not affect. βig-h3 synthesis was efficiently inhibited by dexamethasone at higher dose (100 nM) but not by cyclosporine-A. Conclusion: Production of βig-h3, which is highly upregulated in rheumatoid synovitis, is differentially regulated by inflammatory cytokines.

Lonicerae Flos has antibacterial effects against Staphylococcus aureus, streptococci, pneumococci, Bacillus dysenterii, Salmonella typhi, and paratyphoid. It is an antiviral agent. The herb has a cytoprotective effect against $CCl_{4}-induced$ hepatic injury. It has antilipemic action, interfering with lipid absorption from the gut. Nowadays this herb is used mainly in the treatment of upper respiratory infections, such as tonsillitis and acute laryngitis. It is also used in the treatment of skin suppurations, such as carbuncles, and to treat viral conjunctivitis, influenza, pneumonia, and mastitis. Lonicerae Flos is dried flower buds of Lonicera japonica, L. hypoglauca, L. confusa, or L. dasystyla. But, for the most part, we use whole plant of Lonicera japonica, as a flower bud of it. And, little is known of the original copy of effects of whole plant, except for the 'Bon-Cho-Gang-Mok', which is written the effects of flower of Lonicera japonica are equal to effects of leaves and branch of it. The present study was conducted to evaluate the effect of flower and whole plant of Lonicera japonica on the regulatory mechanism of cytokines, inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) for the immunological activities in Raw 264.7 cells. In Raw 264.7 cells stimulated with lipopolysaccharide (LPS) to mimic inflammation, flower and whole plant of Lonicera japonica water extracts inhibited nitric oxide production in a dose-dependent manner and abrogated iNOS and COX-2. Flower and whole plant of Lonicera japonica water extract did not affect on cell viability. To investigate the mechanism by which flower and whole plant of Lonicera japonica water extract inhibits iNOS and COX-2 gene expression, we examined the on phosphorylation of inhibitor ${\kappa}B{\alpha}$ and assessed production of $TNF-{\alpha}$, $interleukin-1{\beta}$ $(IL-1{\beta})$ and interleukin-6 (IL-6). Results provided evidence that flower and whole plant of Lonicera japonica inhibited the production of $IL-1{\beta}$, IL-6 and activated the phosphorylation of inhibitor ${\kappa}B{\alpha}$ in Raw 264.7 cells activated with LPS. These findings suggest that flower and whole plant of Lonicera japonica can produce anti-inflammatory effect, which may play a role in adjunctive therapy in Gram-negative bacterial infections, respectively.

두부의 기능성 및 저장성을 향상시킬 목적으로 큰느타리버섯 균사체를 이용한 발효두부를 제조하여 물과 메탄올로 추출하여 면역세포 활성에 미치는 효과를 조사하였다. 큰느타리버섯 균사체를 배양하기 위한 최적 배지는 PD broth 배지인 것을 확인하였으며, 큰타리버섯 균사체를 이용한 두부의 최적 발효기간은 7일 정도가 적당하였다. 큰느타리버섯 균사체를 이용하여 발효한 두부의 물 및 메탄올추출물은 0.01 ㎍/mL 농도 이상에서 비장세포의 증식을 유도하였으며, 이들 추출물은 IL-6, IFN-γ 분비를 유도하는 것으로 나타났다. 발효두부 물 추출물은 대조군에 비해 대식세포의 일산화질소 생산을 1 ㎍/mL 농도 이상에서 유의적으로 증가시키는 것을 알 수 있었으며, 메탄올 추출물은 10 ㎍/mL 농도 이상에서 그 생산을 증가시켰다. 발효두부 추출물들은 대식세포가 분비하는 IL-6, TNF-α, IL-1β 및 GM-CSF 분비량을 유의하게 증가시켰다. 따라서 큰느타리버섯 균사체로 발효한 두부는 기능성 두부로 개발이 가능하리라 생각된다. In order to improve the functional benefits and storage properties of soybean tofu, fermented tofu was developed using Pleurotus eryngii mycelia. The immune activities of water and methanol extracts of the tofu were investigated. The optimal medium for the growth of Pleurotus eryngii mycelia was PD broth medium and the optimal fermentation period for the tofu was 7 days. The water and methanol extracts of the fermented tofu induced the proliferation of spleen cells at above 0.01 ㎍/mL. The water extract increased IL-2, IFN-γ production, while the methanol extract increased IFN-γ synthesis. The water and methanol extracts of the fermented tofu induced the NO production in RAW264.7 macrophage cells at above 1 ㎍/mL and above 10 ㎍/mL concentration, respectively. The extracts also significantly increased the production of IL-6, TNF-α, IL-1β and GM-CSF in the cells. These results suggest that the tofu fermented with Pleurotus eryngii mycelia could be developed as a functional tofu.
