Objective To explore the effect of blocking BTLA-HVEM (herpesvirus entry mediator-B and T lymphocyte attenuator) pathway on dendritic cell function and the related immunological mechanisms. Methods Murine BTLA extracellular domain eukaryotic expression vector psBTLA was constructed by gene recombination and transfected CHO by Lipofection method. Mouse bone marrow cells were induced to differentiate into DCs by GM-CSF plus IL-4. Expression of BTLA and HVEM on DCs was detected after HSPT0-TC-1 peptide complex stimulation by FACS. Expression of BT-1 and secretion of IL-12 were detected after HSP70-TC-1 peptide complex plus psBTLA transfected CHO culture supernatant stimulation on DCs. Pretreated DCs co-cultured with the same genetic background mouse splenocytes and lymphocytes proliferation and cytokine secretion were detected. Effect of psBTLA gene transfer in vivo on BT-1 expression of DCs and tumor growth on tumor-bearing mice was detected. Results Extracellular domain of murine BTLA was successfully constructed, psBTLA stable transfection CHO cells were obtained and expression of BTLA extracellular domain(sBTLA) was detected the in its culture supernatant. BTLA and HVEM expression of DCs were increased after stimulation by the antigen peptide complex. When DCs were treated with antigen peptide complex plus culture supernatant containing sBTLA, B7-1 expression and IL-12 secretion were increased. Co-cultured with splenocytes, lymphocytes proliferation and cytokine secretion, such as IL-2 and IFN-γ,, were also increased. Gene transfection with psBTLA in vivo promoted B7-1 expression on DCs and inhibited cervical cancer cells growth. Conclusion Blockade of BTLA-HVEM inhibitory pathway with sBTLA can further improve DCs function, activation of lymphocytes and promote antitumor immune response.

Objective To investigate the synergistic therapy effects of B and T lymphocyte attenuator(BTLA) extracellular domain in combination with heat shock protein 70 (HSP70)-TC-1 antigen peptide complex on the mouse model of cervical cancer and the related immunological mechanisms. Methods(1)Detecting the BTLA and herpesvirus entry mediator (HVEM) gene expression in the tumor microenvironment after C57BL/6 mice were inoculated with TC-1 tumor cells by realtime PCR; BTLA,HVEM expression on tumor infiltrating lymphocytes cell surface were detected by flow cytometry (fluorescence intensity). (2) According to different treatments, tumor-bearing mice were divided into 5 groups, which was injected with pcDNA3. 1 (empty vector plasmid as control), psBTLA (vector plasmid which expresses BTLA extracellular domain), HSP70 (HSP70-TC-1 cell peptide complex), HSP70 +pcDNA3.1 or HSP70 + psBTLA, respectively. The weight of tumor was recorded. The expression of immunoregulatory genes in tumor microenvironment were detected. The change of lymphocyte amount and cytotoxicity were detected too; lymphocyte proliferation activity was measured by tritium thymidine incorporation assay; the concentration of interleukin (IL) 2 and interferon-γ(IFN-γ) in supernatants of spleen lymphocyte were measured by enzyme-linked immunosorbent assay (ELISA). Results (1) BTLA gene expression was gradually increased after tumor cells inoculation. The highest expression level was 2. 83 + 0. 35 at 14th day, which had statistical significance difference with the 7th day expression of 1.66±0. 25 (P < 0. 05). While HVEM mRNA expression did not change significantly (P > 0. 05). The 7th and 14th day after TC-1 cells inoculation, the average fluorescence intensity of BTLA expression on the surface of tumor infiltrating lymphocytes was 33.5 and 51.8, respectively, in which there was statistically significant difference (P <0. 05); while the difference of HVEM expression was not statistically significant (57. 2 vs 49. 3 ,P >0. 05). (2)The 28th day after inoculation, tumor inhibition rate of HSP70 + psBTLA group was 88%, which was significantly higher than other treatment groups (P <0. 05). The 28th day after TC-1 cells inoculation, combination therapy not only promoted IFN-γ and IL-2 gene (3. 12 + 0.71,3.20 + 0. 62)expression but also reduced transforming growth factor-β (TGF-β), Foxp3 and IL-10 expression (0. 25±0. 03,0. 19 +0. 03,0. 31 +0. 04;P <0. 05). It also promoted CD8+ T lymphocyte infiltration(52 +6)/high power field, cytotoxicity (65.5±2.4) %, proliferation (15.0 × 103 cpm) and cytokine IL-2 , IFN-γsecretion(824±51), (1096±112) pg/ml, which were all significantly higher than other groups (P <0. 05). Conclusion The effect of immunotherapy on tumor can be augmented by the combination of psBTLA which expresses extracellular domain of BTLA and HSP70-TC-1 tumor antigen peptide complex,which could improve the expression of the related immunoregulatory genes to establish a much better microenvironment in favor of anti-tumor immune response against the mice model of the cervix carcinoma.

ObjectiveTo investigate the effect of synergistic intervention of interferonα (IFNα) and thymopentin (TP5) on the mRNA expression of apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like 3A (APOBEC3A) and apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like 3B (APOBEC3B) in HepG2.2.15 cells. MethodsHepG2.2.15 cells were divided into blank control group, IFNα treatment group, TP5 treatment group, and IFNα+TP5 treatment group, and at 12, 24, 48, and 72 hours of treatment, quantitative real-time PCR was used to measure the mRNA expression of APOBEC3A and APOBEC3B in HepG2.2.15 cells. An analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the blank control group, the IFNα treatment group and the IFNα+TP5 treatment group had a significant increase in the mRNA expression of APOBEC3A at 12, 24, 48, and 72 hours of treatment (all P<0001). Compared with the IFNα treatment group, the IFNα+TP5 treatment group had a significant increase in the mRNA expression of APOBEC3A at these four time points (all P<0.001). TP5 treatment had no significant influence on the mRNA expression of APOBEC3A at each time point (all P>0.05). There was no significant difference in the mRNA expression of APOBEC3B between the blank control group and the treatment groups (all P>0.05). ConclusionIFNα combined with TP5 can significantly upregulate the mRNA expression of APOBEC3A in HepG2.2.15 cells.

BACKGROUNDIn patients with chronic total occlusion (CTO) and multivessel coronary artery disease, the comparison of surgical and the percutaneous revascularization strategies has rarely been conducted. The aim of this study was to compare long term clinical outcomes of drug eluting stent (DES) implantation with coronary artery bypass surgery (CABG) in the patients with CTO and multivessel disease.
METHODSFrom a prospective registry of 6000 patients in our institution, we included patients with CTO and multivessel coronary artery disease who underwent either CABG (n = 679) or DES (n = 267) treatment. Their propensity risk score was used for adjusting baseline differences.
RESULTSAt a median follow-up of three years, propensity score adjusted Cox regression analysis showed that the rate of major adverse cardiac cerebrovascular events (MACCE) was lower in CABG group (12.7% vs. 24.3%, hazard ratio (HR) 1.969, 95%CI 1.219 - 3.179, P = 0.006) mainly due to lower rate of target vessel revascularization in CABG group than in DES group (3.1% vs. 17.2%, HR 16.14, 95%CI 5.739 - 45.391, P < 0.001). The incidence of cardiac death or myocardial infarction (composite end point) was not significantly different between these two groups. On multivariate analysis, the significant predictors of MACCE were only the type of revascularization. Age, left ventricular ejection fraction (LVEF), and complete revascularization were identified as significant predictors of composite end points.
CONCLUSIONSOur study shows that in patients with CTO and multivessel coronary disease, DES can offer comparable long term outcomes in cardiac death and myocardial infraction free survival in comparison with CABG. However, there is an increased rate of MACCE which results from more repeat revascularizations. Obtaining a complete revascularization is crucial for decreasing adverse cardiac events.
