Relationship of human leukocyte antigen class II genes with the susceptibility to hepatitis B virus infection and the response to interferon in HBV-infected patients

AIM： To study the relationship of human leukocyte antigen （HLA）-DRB1 and -DQB1 alleles with the genetic susceptibility to HBV infection and the response to interferon （IFN） in HBV-infected patients. METHODS： Low-resolution DNA typing kit was used to determine HLA-DR-1 and -DQB1 genes in 72 patients with chronic hepatitis B （CHB） and HLA-DRB1 in 200 healthy people ready to donate their bone marrow in Shanghai. Among CHB patients, 35 were treated with IFNα-1b for 24 wk. RESULTS： The frequencies of HLA-DRBI＊06, DRBI＊08 and DRB1＊16 alleles in 72 patients were higher than in 200 healthy people （2.08% vs0%, OR = 3.837, P= 0.018; 11.11% vs5.50%, OR = 2.148, P= 0.034; and 6.94% vs 3.00%, OR = 0.625, P = 0.049, respectively）; whereas that of DRBI＊07 allele was lower （2.78% vs 7.75%, OR = 0.340, P= 0.046）. The frequency of HLA-DRBI＊ 14 allele was higher in 11 responders to IFN compared with 24 non-responders （18.18% vs2.08%, OR = 10.444, P = 0.031）, whereas that of DQBI＊07 allele was inverse （9.09% vs37.50%, OR = 0.167, P= 0.021）. CONCLUSION： The polymorphism of HLA class II may influence the susceptibility to HBV infection and the response to IFN in studied CHB patients. Compared with other HLA-DRB1 alleles, HLA-DRBI＊06, DRBI＊08, and DRB1＊16 may be associated with chronicity of HBV infection, HLA-DRBI＊07 with protection against HBV infection, and HLA-DRB1＊14 allele may be associated with a high rate of the response of CHB patients to IFN treatment. Compared with other HLA-DQB1 alleles, HLA-DQBI＊07 may be associated with low response rate to IFN. 2005 The WJG Press and Elsevier Inc. All rights reserved

Apoptosis mechanisms of human gastric cancer cell line MKN-45 infected with human mutant p27

AIM: To explore the inducing effect of human mutant p27 gene on the apoptosis of the human gastric cancer cell line MKN-45 and its associated mechanisms. METHODS: The recombinant adenovirus Ad-p27mt was constructed to infect the human gastric cancer cell line MKN-45. Using flow cytometry, TUNEL assay and DNA fragment analysis, we measured the apoptotic effect of Ad-p27mt on the human gastric cancer cells. RESULTS: Ad-p27mt was successfully constructed and the infection efficiency reached 100%. After 18 h of infection, we observed an apoptotic hypodiploid peak on the flow cytometer before G1-S and apoptotic characteristic bands in the DNA electrophoresis. The apoptotic rate detected by TUNEL method was significantly higher in the Ad-p27mt group (89.4±3.12%)compared to the control group (3.12±0.13%, P ＜ 0.01).CONCLUSION: Human mutant p27 can induce apoptosis of the human gastric cancer cells in vitro.

Expression of Human Interferon α 2b Gene in Ginseng Cells

The human interferon α 2b（hIFN-α2b） gene was cloned into binary vector pBI121 to obtain plant expression vector pBIFN. The recombinant plasmid pBIFN was transferred into Agrobacterium tumefaciens strain LBA4404. Then the hIFN-α2b gene was introduced into ginseng callus cells via Agrobacterium-mediated transformation and the ginseng cell line carrying hIFN-α2b gene was selected on G418-containing medium. The presence of target gene in transformed cells was confirmed by PCR and RT-PCR. The results indicate that hIFN-α2b gene has been integrated into the ginseng cells＇ genome, with transcription products, hIFN-α2b expressed by the transgenic ginseng cells was detected by Western blot. It was shown that a specific protein band at 19000 could be observed. Cytopathic effect（CPE） inhibition assay using the W1SH-VSV system shows that the mean antiviral activity of expressed hlFN-a2α was 6.0× 10^4 IU/mL.

Development of novel-nanobody-based lateral-flow immunochromatographic strip test for rapid detection of recombinant human interferon a2b

Recombinant human interferon a2b(rhIFNa2b)is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C.The current identification test for rhIFNa2b is complex.In this study,an anti-rhIFNa2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNa2b.RhIFNa2b was used to immunize an alpaca,which established a phage nanobody library.After five steps of enrichment,the nanobody I22,which specifically bound rhIFNa2b,was isolated and inserted into the prokaryotic expression vector pET28a.After subsequent purification,the physicochemical properties of the nanobody were determined.A semiquantitative detection and rapid identification assay of rhIFNa2b was developed using this novel nanobody.To develop a rapid test,the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips.The developed rhIFNa2b detection assay had a limit of detection of 1 mg/mL.The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products.The principle of this novel assay is generally applicable for the rapid testing of other commercial products,with a great potential for routine use in detecting counterfeit recombinant protein products.

Controlling malignant pericardial effusion by intrapericardial administration of recombinant mutant human tumor necrosis factor in patients with carcinoma

Objective: To evaluate the therapeutic efficacy of injecting recombinant mutant human tumor necrosis factor (rmhTNF) into pericardial cavity of carcinoma patients with malignant pericardial effusion. Methods: In 20 cases of malignant pericardial effusion, the intrapericardial catheter was inserted into pericardial cavity, and then rmhTNF of 1.5 × 107 U was infused. The infusion was repeated every 5-7 days with the total 4-6 times. If the effusion disappeared, rmhTNF was then used 2 more times and then the intrapericardial catheter was pulled out. Results: Of 20 patients, 14 were complete response (CR), 4 were partial response (PR) and 2 no change (NC). The disappearance of effusion in 6 cases lasted for more than 6 months. Conclusion: Injecting rmhTNF into pericardial cavity may be a better way to control malignant pericardial effusion and has mild side effects.

Effects and Interactions of Prostaglandins and Interferon－γ on Steroidogenesis ofHuman Luteal Cells

Previous work from our laboratory has demonstrated that T lymphocyte-derived cytokine,interferon-gamma(IFN-γ) may play a role in human luteal regression by inhibiting luteal progesterone production.Prostaglandin F2αhas been known as an important luteolytic factor in a wide range of mammalian species.It was of interest to investigate the effects of IFN-γon prostaglandin synthesis and their possible interaction with the inhibition on human luteal steroidogenesis.Human luteal cells were cultured for four days in the presence or absence of IFN-γ.Simultaneously, the productions of progesterone,prostaglandin F2α(PGF2α),Prostaglandin E2(PGE2),and 6-ketoprostaglandin F1α(PGF1α) were evaluated.Concomitant with the inhibition of progesterone production induced by IFN-γ,αbiphasic pattern of response of prostaglandin synthesis was observed,i.e.a slight decrease of PGF2αand PGF1αafterα48 h exposure to IFN-γ while an increase of PGE2 after 96 h. In a separate experiment,a luteotropic action of PGE2 and PGF2a on human luteal cells from different stages was observed during 48 and 96 h periods of culture.In addition,while indomethacin(INDO) treatment markedly blocked the prostaglandin synthesis, the hasal as well as hCG stimulated progesterone production was still inhibited by IFN-γas usual.These results suggested that prostaglandins appeared to be not responsible for the observed inhibition Of progesterone production since the inhibitory effect was not influenced by concurrent treatment with INDO which suppressed prostaglandin synthesis.

Apoptosis of Human Pancreatic Carcinoma Cells Induced By All-Trans Retinoic Acid and Interferon

Objective： To investigate the apoptosis of human pancreatic carcinoma PC3 cells induced by the combination of all-trans retinoic acid （ATRA） with interferon alpha （IFN-α）. Methods： PC3 cells were treated with ATRA and IFN-α. The inhibitory rate of PC3 cell proliferation was detected using MTT method. Cellular apoptosis was determined with flow cytometry. The percentage of PC3 cell apoptosis was assayed using TUNEL methods. Results： ATRA and IFN-α could inhibit cellular proliferation and induces cellular apoptosis of PC3 cells. The inhibitory effect was stronger when the ATRA and IFN-α were combined as a therapy. Conclusion： ATRA inhibits the proliferation of PC3 cells and induce the apoptosis of PC3 cells. The combination of IFN-α with ATRA may enhance these effects on PC3 cells.

Effects of increased human tumor necrosis factor-like molecule 1A expression in peripheral blood of children with acute Guillain-Barre syndrome on interferon-gamma secretion

BACKGROUND： Human tumor necrosis factor-like molecule 1A （hTL1A） is a strong T helper cell type 1 （Thl） co-stimulator. Guillain-Barre syndrome （GBS） is an autoimmune disorder of the nervous system, which is mediated by Thl cells. OBJECTIVE： To determine hTL1A expression in peripheral blood T lymphocytes of acute GBS children and the effects of hTL1A on secretion of interferon-γ. DESIGN, TIME AND SETTING： A randomized, controlled, neuroimmunological in vitro study was performed at the Central Laboratory of First Hospital of Jilin University, China from November 2005 to November 2007. MATERIALS： Venous blood samples were obtained from 6 healthy donors, aged 6-12 years （all routine blood examination items were normal）, and 6 additional children with acute GBS, aged 6-12 years. The GBS children fell ill within 1 week and were not treated with hormones or immunoglobulin Purified recombinant human soluble tumor necrosis factor-like molecule 1A （rhsTL1A, 1 mg/mL, relative molecular mass 22 000, 6× His tag, soluble form） was supplied by the Central Laboratory of First Hospital of Jilin University, China. METHODS： Peripheral blood mononuclear cells were isolated from healthy donors using the standard Ficoll gradient centrifugation and were incubated in 96-well culture plates. The cells were assigned to the following groups： control （2 μg/mL phytohemagglutinin）, 2μg/mL phytohemagglutinin ＋ 25, 100 and 400 ng/mL rhsTL1A. T cell proliferation was quantified using the tritiated thymidine （3H-TdR） method. Serum interferon-γ levels in acute GBS children were detected by enzyme-linked immunosorbent assay （ELISA）. The ratio of hTL1A-positive T cells to CD3-positive T cells in peripheral blood of acute GBS children was determined using flow cytometry. Following in vitro pre-activation of peripheral blood mononuclear cells by 2 μg/mL phytohemagglutinin, the peripheral blood mononuclear cells were treated with 400 ng/mL exogenous rhsTLIA. Finally, peripheral blood mononuclear cell-secreted interferon-γlevels were measured by ELISA. MAIN OUTCOME MEASURES： The following parameters were measured： rhsTLIA stimulation index to stimulate proliferation of T cells; the serum interferon-γ levels in acute GBS children; the ratio of hTL1A-positive cells to CD3-positive cells; the levels of interferon-γ secreted by peripheral blood mononuclear cells in acute GBS children, as well as rhsTL1A-stimulated interferon-γ levels. RESULTS： T cell proliferation assay revealed that the stimulation index in each rhsTL1A group was greater than the control group. The stimulation index of the 400 ng/mL rhsTL1A group was the greatest. Serum interferon-γ levels in acute GBS children were significantly greater than the control group （P 〈 0.05）. The ratio of hTLIA＋ CD3＋ T cells to CD3＋ T cells in acute GBS children was significantly greater than the control group （P 〈 0.01 ）. Phytohemagglutinin stimulated peripheral blood mononuclear cells to a greater extent than 400 ng/mL rhsTL1A in the acute GBS group, and the secreted interferon-γ levels were significantly increased （P 〈 0.05）. CONCLUSION： In T cells pre-activated with 2 μg/mL phytohemagglutinin, proliferation was effectively increased with 400 ng/mL rhsTL1A treatment. Expression of hTLIA was increased in activated T cells from peripheral blood of acute GBS children, followed by increased interferon-γ secretion. These mechanisms are considered to be part of the pathological process that induces the secretion of inflammatory cytokines in GBS syndrome.

Construction of retroviral vectors to induce a strong expression of human interferon-β gene in human hepatoma cells

Establishing the hepatoma cell-specific expression of human interferon gene mediated by retroviral vectors. Methods: Human interferon-β complementary DNA (IFN-β cDNA) was inserted into polylinker site of pMNSM retroviral vector to construct recombinant retroviral vector pMNSIFNB, where the transcription of IFN-β gene was driven by SV40 early region promoter, and MNAIFNB, where the transcription of IFN-β gene was driven by SV40 early region promoter regulated by α-fetoprotein enhancer. The retroviral constructs were respectively introduced into PA317 amphotropic packaging cells by means of lipofectamine mediated gene transfer procedure. The plasmids transfection efficiency was among (4-25)ｘ103 colonies/μg DNA/106 PA317 cells. The retrovirus infection efficiency was among (4. 5-500)ｘ104 Colony Forming Units (CFU)/ml. The recombinant retroviruses were used to infect human hepatoma cells, renal cell carcinoma cells and melanoma cell lines in the presence of 4 μg/ml polybrene. Results: Dot hybridization of total RNA from the neomycin resistant colonies and interferon expression assay indicated that human α-fetoprotein enhancer induced efficient and specific transcription and expression of IFN-β gene driven by the promoter of different origin in human hepatoma cells by which α-fetoprotein was highly produced. Conclusion: Cis-active element of α-fetoprotein gene can drive IFN-β gene specifically expressed in human hepatoma cells, which presents some valuable materials for the hepatoma-specific immune gene therapy.
