Objective To investigate the effect of insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2) on the proliferation, migration and tumor immune microenvironment of colorectal cancer cells and its possible molecular mechanism. Methods The Cancer Genome Atlas (TCGA) database was used to analyze the expression levels of IGF2BP2 and MYC in colorectal cancer and adjacent tissues. The expression of IGF2BP2 in HCT-116 and SW480 human colorectal cancer cells was silenced by RNA interference (RNAi), and the silencing effect was detected by quantitative real-time PCR. After knocking down IGF2BP2, colony formation assay, CCK-8 assay and 5-ethynyl-2'-deoxyuridine (EdU) assay were employed to detect cell colony formation and proliferation ability. Transwell^TM assay was used to detect cell migration ability. Quantitative real-time PCR was used to detect the mRNA expression of IGF2BP2, MYC, tumor necrosis factor-α (TNF-α), transforming growth factor-β (TGF-β) and interleukin-10 (IL-10). The protein expression of IGF2BP2 and MYC was detected by western blot. The binding ability of IGF2BP2 and MYC in HCT-116 cells was detected by quantitative real-time PCR after RNA immunoprecipitation. Results The results of TCGA database showed that the expression of IGF2BP2 and MYC in colorectal cancer tissues was significantly higher than that in adjacent tissues, and the survival time of colorectal cancer patients with high expression of IGF2BP2 was shorter. After silencing IGF2BP2, the viability, proliferation and migration of HCT-116 and SW480 cells were decreased. The mRNA expression of MYC, TGF-β and IL-10 in IGF2BP2 knockdown group was significantly decreased, while the expression of TNF-α mRNA was increased. The expression of MYC protein and the stability of MYC mRNA were significantly decreased. RIP-qPCR results showed that IGF2BP2 could bind to MYC mRNA. Conclusion Knockdown of IGF2BP2 inhibits colorectal cancer cell proliferation, migration and promotes tumor immunity by down-regulating MYC expression.

The present study was designed to investigate the antimalarial activity of synthetic hepcidin and its effect on cytokine secretion in mice infected with Plasmodium berghei. The mice were infected with P. berghei intravenously and treated with hepcidin according to 4-day suppression test and Rane's test. The serum levels of interleukins (IL-1β, IL-2, IL-6, IL-10, IL-12p70, and IL-17A), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ) in the experimental mice were determined using a cytometric bead array (CBA) kit. The survival rate of the infected mice was also registered. Additionally, the serum iron, alanine transaminase (ALT), aspartate transaminase (AST), and total bilirubin (BIL) were detected to evaluate liver functions. Hepcidin exerted direct anti-malarial function in vivo and increased survival rate in a dose-dependent manner. In addition, the secretion of T helper cell type 1 (Th1), Th2, and Th17 cytokines, TNF-α, and IFN-γ were inhibited by hepcidin. In conclusion, our results demonstrated that synthetic hepcidin exerts in vivo antimalarial activity and possesses anti-inflammatory function, which provides a basis for future design of new derivatives with ideal anti-malarial activity.

OBJECTIVETo study the influence of Yanyankang powder on Th1/Th2 in rats with experimental autoimmune uveitis (EAU).

METHODSThe EAU models were induced in Lewis rats by immunization with interphotoreceptor retinoid binding protein (IRBP) 1177-1191 in complete Freund's adjuvant. The rats were randomly divided into 3 groups: a model control group, a Yanyankang group, and a prednisone group, 9 rats in each group. The model control group was intervened with saline solution by gavage. The Yanyankang group was intervened with Yanyankang powder 4 g/(kg day) by gavage. The prednisone group were intervened with prednisone acetate tablets 5 mg/(kg d) by gavage. All groups were intervened after immunization once every 2 days for 18 days and monitored by slit-lamp biomicroscopy daily until day 18. The levels of gamma interferon (INF-γ) and interleukin-10 (IL-10) in the supernatants of T cells were determined by enzyme-linked immunosorbent assay. Polymerase chain reaction (PCR) technology was used for measuring Th1 and Th2 related cytokine mRNA expressions.

RESULTSSlighter intraocular inflammation was found in the Yanyankang group and the prednisone group than the control group. The levels of the IFN-γ and IL-10 in the supernatants of the spleen lymph node cells were 382.33±6.30, 155.87±4.46 μg/L in the Yanyankang group and 270.93±7.76, 265.32±11.88 μg/L in the prednisone group. Both had significant differences compared with the control group (941.53±8.59, 20.67±4.65 μg/L; =0.01). The PCR results showed the same tendency.

CONCLUSIONYanyankang powder showed favorable effects in the rats with EAU by influencing the function of Th1 and Th2 cells.

PURPOSE: High mobility group box 1 (HMGB1) plays a central role in the pathogenesis of sepsis and multiple organ dysfunction syndromes. We investigated the associations of a single nucleotide polymorphism (SNP; rs1045411) in HMGB1 with various clinical parameters, severity, and prognosis in patients with sepsis, severe sepsis, or septic shock. MATERIALS AND METHODS: We enrolled 212 adult patients followed for 28 days. All patients were genotyped for rs1045411, and the serum levels of HMGB1 and several cytokines were measured. RESULTS: The proportions of patients according to genotype were GG (71.2%), GA (26.4%), and AA (2.4%). Among patients with chronic lung disease comorbidity, patients with a variant A allele had higher positive blood culture rates and higher levels of various cytokines [interleukin (IL)-1beta, IL-6, IL-10, IL-17, and tumor necrosis factor-alpha] than those with the GG genotype. In the analysis of those with diabetes as a comorbidity, patients with a variant A allele had higher blood culture and Gram-negative culture rates than those with GG genotypes; these patients also had a higher levels of IL-17. In the analysis of those with sepsis caused by a respiratory tract infection, patients with a variant A allele had higher levels of IL-10 and IL-17 (all p<0.05). This polymorphism had no significant impact on patient survival. CONCLUSION: The variant A allele of rs1045411 appears to be associated with a more severe inflammatory response than the GG genotype under specific conditions.

Dendritic cells (DCs), which are regarded as the most potent antigen-presenting cells, are involved in innate and adaptive immunity. Upon uptake of pathogens, DCs express cell surface markers and secrete cytokines. In this study, we analyzed production of cytokines and found that interleukin (IL)-10 and transforming growth factor (TGF)-beta production significantly increased in bone marrow-derived DCs and a mouse DC line, DC2.4, after treatment with crude antigen (CA) from liver fluke, Clonorchis sinensis. However, expression patterns of several activation molecules did not change. In addition, following treatment of DC2.4 cells with antigen from the lung fluke, Paragonimus westermani, production of IL-10 and TGF-beta significantly increased compared with groups treated with other parasite antigens, Spirometra erinacei plerocercoid CA and Echinococcus granulosus hydatid cystic fluid. We also found that treatment of DC2.4 cells with C. sinensis CA resulted in rapid and significant phosphorylation of extracellular signal-regulated kinase 1/2, a mitogen-activated protein kinase. Following treatment of DC2.4 cells with C. sinensis CA, treatment with an inhibitor specific to an extracellular signal-regulated kinase inhibited production of IL-10 and TGF-beta. Our results suggest that CA from C. sinensis has a role in the anti-inflammatory function of DC cells by inducing IL-10 and TGF-beta through activation of extracellular signal-regulated kinase 1/2.

We examined the possible anti-inflammatory mechanisms of gabapentin in the attenuation of neuropathic pain and the interaction between the anti-allodynic effects of gabapentin and interleukin-10 (IL-10) expression in a rat model of neuropathic pain. The anti-allodynic effect of intrathecal gabapentin was examined over a 7-day period. The anti-allodynic effects of IL-10 was measured, and the effects of anti-IL-10 antibody on the gabapentin were assessed. On day 7, the concentrations of pro-inflammatory cytokines and IL-10 were measured. Gabapentin produced an anti-allodynic effect over the 7-day period, reducing the expression of pro-inflammatory cytokines but increasing the expression of IL-10 (TNF-alpha, 316.0 +/- 69.7 pg/mL vs 88.8 +/- 24.4 pg/mL; IL-1beta, 1,212.9 +/- 104.5 vs 577.4 +/- 97.1 pg/mL; IL-6, 254.0 +/- 64.8 pg/mL vs 125.5 +/- 44.1 pg/mL; IL-10, 532.1 +/- 78.7 pg/mL vs 918.9 +/- 63.1 pg/mL). The suppressive effect of gabapentin on pro-inflammatory cytokine expression was partially blocked by the anti-IL-10 antibody. Expression of pro-inflammatory cytokines was significantly attenuated by daily injections of IL-10. The anti-allodynic effects of gabapentin may be caused by upregulation of IL-10 expression in the spinal cord, which leads to inhibition of the expression of pro-inflammatory cytokines in the spinal cords.

OBJECTIVETo retrospectively analyze the quantity and status of the tumor infiltrating regulatory T lymphocytes in breast cancer and the draining lymph nodes, and to elucidate the clinical pathologic significance.

METHODSSeventy-four breast cancer samples with excised axillary lymph nodes were typed and staged histopathologically. The regulatory T lymphocytes were labeled by immunohistochemistry using EnVision method with the monoclonal antibodies against CD25 and Foxp3, and the immunophenotype was analyzed. In addition, the expression of IFN-γ, IL-10 and TGF-β1 mRNA in lymphocytes of lymph nodes draining the tumors was detected by in situ hybridization with the corresponding specific oligo nucleaic acid probes.

RESULTSThe number of CD25(+)Foxp3(+) T cells infiltrating the interstitium was much higher than that in the parenchymal tissue of the cancer. In the tumor draining lymph nodes, CD25(+) cells and Foxp3(+) cells were predominantly distributed in the paracortex with a proliferative pattern. TGF-β1, INF-γ and IL-10 mRNA positive cells showed a similar distribution pattern in the draining lymph nodes. Among the 39 cases with metastatic disease, the lymph nodes with metastases showed a much higher number of CD25(+)Foxp3(+) cells than that without metastases (23.5 vs 17.3 and 23.8 vs 15.5; P < 0.05). However, there was no difference in the density of Foxp3(+)CD25(+) cells in the draining lymph nodes between the death and survival groups (P > 0.05). Cytokine expression of TGF-β1, IL-10 and IFN-γ mRNA in the lymphocytes of draining lymph nodes in 24 cases showed that there were more IL-10 mRNA positive cells in the dead patients than that in the survived patients. A similar trend was observed for TGF-β1 mRNA positive cells but the difference was not statistically significant (P > 0.05). The expression rate of TGF-β1 and IL-10 mRNA in the draining lymph nodes was proportional to that of CD25(+) and Foxp3(+) cells (P < 0.05), and the expression of TGF-β1 positive cells was also proportional to that of IL-10 mRNA positive cells (P < 0.01). The expression of IFN-γ mRNA among these groups showed no significance (P > 0.05).

CONCLUSIONSRegulatory T cells may play important roles in inhibiting the host antitumor immunity, and the presence of increased regulatory T cells and Th2-secreting cells in paracortex with a proliferative pattern in the tumor draining lymph nodes implies that the paracortical proliferation of draining lymph nodes may not reflect positive antitumor effects.

OBJECTIVETo study the immunoregulatory effect of hepatitis B virus (HBV) e antigen (HBeAg) on peripheral blood monocytes (PBMCs).

METHODSPBMCs were isolated from patients with chronic hepatitis B (CHB; both HBeAg- and HBeAg+) and healthy controls, and cultured with recombinant HBeAg. The HBeAg-induced changes in expression of PD-1/PD-L1 were measured by flow cytometry of the cells and in secreted cytokines were measured by enzyme-linked immunosorbent assay of the supernatants. Comparisons between two groups were made by the independent-samples t-test; the relationship between PD-1/B7-H1 level and HBV DNA copy number was evaluated by Spearman's correlation analysis.

RESULTSExposure to HBeAg led to a significant decrease in CD3+CD4+ T lymphocyte-specific expression of IFNa for both the CHB patients' and healthy controls' samples (t = 2.382 and -4.190 respectively, P less than 0.01). For the HBeAg- CHB patients' and healthy controls' samples, the HBeAg exposure led to increased levels of secreted cytokines IL-6, IL-10 and TNFa (t = 2.504, 3.583 and 4.324, P less than 0.01 and t = 3.542, 6.246 and 5.273, P less than 0.01 respectively) and of CD14+ PBMC-specific expression of PD-L1 (t = 4.815 and 3.454, P less than 0.05 respectively). Compared to the HBeAg-negative CHB patients' and healthy controls' samples, the HBeAg+ CHB patients' samples had significantly lower CD3+CD4+ T cell-specific expression of IFNa (t = -3.177 and -4.541, P less than 0.01 respectively), but significantly higher levels of secreted IL-4 (t = 3.382 and 4.393, P less than 0.01 respectively), of CD3+ T cells-specific expression of PD-1/PD-L1 (t = 4.755, 2.942 and 4.518, 4.595, P less than 0.01 respectively), and of CD14+ T cells-specific expression of PD-L1 (t = 5.092 and 5.473, P less than 0.01 respectively). The CD3+ T cells-specific expression of PD-L1 was significantly higher in the samples from HBeAg- CHB patients than from the healthy controls (t = 3.214, P less than 0.01).

CONCLUSIONHBeAg was able to down-regulate the production of Th1-type cytokines (IFNgamma), and up-regulate the secretion of Th2-type cytokines (IL-6, IL-10) and the expression of PD-1/PD-L1on monocytes. These changes are conducive to the formation of immune tolerance to HBV. Therefore, HBeAg may play an important role in immune tolerance to chronic HBV infection.

OBJECTIVETo observe the effect of Huanglian Jiedu IJecoction (HJU) on systemic and vascular immune responses of high fat diet fed apoE deficient (apoE(-/-)) mice.

METHODSEight wild type C57BL6 mice were recruited as the wild type common food group. Totally 24 apoE(-/-) mice were randomly divided into the ApoE'common food group, the ApoE(-/-) hyperlipidemia group, and the ApoE(-/-) hyperlipidemia plus HJD group, 8 in each group. In the present study, the common food mice and high fat fed mice were fed with a chow diet or a high cholesterol diet for 4 weeks. HJD was given to mice in the ApoE(-/-) hyperlipidemia plus HJD group at the daily dose of 5 g/kg by gastrogavage, while equal volume of pure water was given to mice in the rest groups by gastrogavage. Four weeks later, the plasma levels of blood lipids, the ratio of peripheral blood mononuclear cells, and expressions of Toll-like receptor 4 (TLR-4) and CD36 on the monocytes were detected. The pathological changes and expressions of cytokines in local aorta were detected. The plasma cytokine levels in response to lipopolysaccharide (LPS) were analyzed. Results (1) Compared with the wild type common food group, TO, TG, and LDL-O significantly increased in the ApoE(-/-) common food group (P < 0. 05, P < 0.01). Compared with the ApoE(-/-) common food group, TC and LDL-C significantly increased in the hyperlipidemia group (P < 0. 05). There was no statistical difference in each index between the ApoE(-/-) hyperlipidemia group and the ApoE(-/-) hyperlipidemia plus HJD group (P > 0.05). (2) Compared with the wild type common food group, no obvious change of the ratio of peripheral blood mononuclear cells happened, the TLR4 expression level significantly increased in the ApoE'common food group (P < 0. 05). Compared with the ApoE common food group, the ratio of peripheral blood mononuclear cells and the TLR4 expression level significantly increased in the ApoE' hyperlipidemia group (P < 0.05). Compared with the ApoE(-/-) hyperlipidemia group, the ratio of peripheral blood mononuclear cells and the TLR4 expression level significantly decreased. Besides, the CD36 expression level also significantly decreased (P<0.05). (3) After stimulated by LPS for 3 h, compared with the wild type common food group, plasma TNF-ct and IL-b expressions significantly increased in the ApoE(-/-) common food group (P < 0.05). Compared with the ApoE(-/-) common food group, plasma expressions of IL-12, TNF-alpha, MCP-1, and IL-10 increased, but with no statistical difference in the ApoE(-/-) hyperlipidemia group (P > 0.05). After 4-week intervention of HJD, compared with the ApoE(-/-) hyperlipidemia group, the MCP-1 expression was significantly down-regulated, while the IL-10 expression significantly increased, showing statistical difference (P < 0.05). Compared with the wild type common food group, mRNA expression levels of IFN-gamma, MCP-1 , TNF-alpha, IL-10, and IL-1beta significantly increased (P < 0. 05, P < 0.01). Compared with the ApoE(-/-) common food group, not only mRNA expression levels of IFN-gamma, MCP-1, TNF-alpha, and IL-1beta, further significantly increased, but also IL-12, IL-10, and TGF-beta significantly increased (P < 0. 05, P < 0. 01). After 4-week intervention of HJD, compared with the ApoE(-/-) hyperlipidemia group, mRNA expression levels of MCP-1, TNF-alpha, IL-1beta, and IL-12 significantly decreased in the ApoE(-/-) hyperlipidemia plus HJD group (P < 0.05, P < 0.01).

CONCLUSIONSHigh fat diet induced systemic reaction and inflammatory reactions of local vessels. The local inflammatory response of vessels exceeded systemic inflammatory response. Intervention of HJD could attenuate inflammatory response, especially in local arteries. Meanwhile, it enhanced systemic anti-inflammatory reactions.

OBJECTIVETo explore the regulatory mechanism of Xiaoyin Recipe () on the T helper 1/T helper 2 (Th1/Th2) immune balance.

METHODSThirty-six experimental animals were divided into three groups, 12 rats in each group: blank control group (B group), negative control group (N group), and Xiaoyin Recipe treatment group (T group). The latter two groups received immunization of experimental autoimmune thyroiditis (EAT), and T group were treated with Xiaoyin Recipe for a month. Then, the expression of Th1-Th2-related genes in peripheral blood mononuclear cells (PBMCs) were screened with Oligo GEArray Rat Th1-Th2-Th3 Microarray. The expressions of tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), T-box expressed in T-cells (T-bet), and GATA-binding protein-3 (GATA-3) were detected by real-time polymerase chain reaction (RT-PCR).

RESULTSGene array screening showed that compared to N group, in T group after Xiaoyin Recipe treatment, 3 genes were upregulated in EAT rats, including interleukin-27 receptor alpha (IL-27rα), glomulin (Glmn), and GATA-3, while 38 genes were downregulated, such as CD28, IL-18, signal transducer, and activator of transcription 1 (STAT1), T-bet, TNF receptor superfamily member 4 (TNFRSF4), TNF ligand superfamily member 5 (TNFSF5), and TNF receptor superfamily member 5 (TNFRSF5). While RT-PCR showed that there was an increased level of TNF-α mRNA (P<0.01), an elevated ratio of T-bet/GATA-3, and a decreased level of IL-10 mRNA in PBMC of N and T group compared to B group (P <0.01); and after treatment with Xiaoyin Recipe, IL-10 mRNA level increased (P <0.01), while TNF-α mRNA level and T-bet/GATA-3 ratio decreased in T group compared to N group (P <0.01).

CONCLUSIONXiaoyin Recipe for psoriasis could induce a Th1/Th2 balance drift toward Th2 in PBMC of EAT rats and thus improve the conditions.
