Interferon-α (IFN-α) resistance is a major hurdle in the treatment of hepatocellular carcinoma (HCC). Signal transducers and activators of transcription 1 (STAT1) play a key role in exerting the antiproliferative and proapoptotic effects of IFN-α on tumors. In this study, we aimed to investigate whether resveratrol can promote IFN-α-induced growth inhibition and the apoptosis on HCC cells through the SIRT/STAT1 pathway. We found that IFN-α induced growth inhibition and apoptosis of SMMC7721 cells, and the effects could be significantly enhanced and blocked by resveratrol and EX527, respectively...

Interferon-tau (IFN-τ), a novel type I interferon, is produced by trophoblast cells in ruminants. Previous studies have confirmed that IFN-τ could induce immunological tolerance in humans and other species. However, there are few reports on whether IFN-τ has a protective effect on embryo implantation failure caused by excessive inflammation at the maternal-fetal interface. In our study, a mouse model of lipopolysaccharide (LPS)-induced implantation failure was successfully established, and we investigated the protective effects of IFN-τ...

A thrombopoiesis-stimulating protein, the myeloproliferative leukemia virus protooncogene (Mpl) ligand romiplostim (RP), is currently approved as a therapeutic agent for idiopathic thrombocytopenic purpura in many countries. Although the action of the initial MPL ligand thrombopoietin (TPO) on human megakaryocytic regeneration from irradiated human hematopoietic stem cells has been examined, there are few reports on the action of RP. In the present study, freshly prepared nonirradiated and 2-Gy X-irradiated human CD34 positive (CD34+ ) cells from placental umbilical cord blood were cultured with a combination of RP and various cytokines...

To explore the immunological mechanisms underlying the effect of exogenous interleukin-34 (IL-34) on collagen-induced arthritis (CIA) in mouse. We established a CIA mouse model and injected exogenous recombination mouse IL-34 (rmIL-34) intraperitoneally. The articular index (AI) was measured according to the amount of erythema, swelling, or joint rigidity. The concentrations of TNF-α, IL-17, and IL-6 in CIA mice sera were measured by enzyme-linked immunosorbent assay (ELISA). The mRNA expression levels of TNF-α, IL-17, and IL-6 in CIA synovial tissue were detected by reverse transcription PCR...

Recombinant human thrombopoietin (rhTPO) is a key determinant of therapy for chemotherapy-induced thrombocytopenia (CIT) in patients with breast cancer. To assess the predictive value of preoperative inflammatory cells for response to rhTPO in breast cancer patients, a total of 198 female patients with breast cancer were enrolled between June 2011 and December 2016 in Liaoning Cancer Hospital. Peripheral blood samples before rhTPO therapy were obtained, the ratios of helper T cell (CD4+ ), cytotoxic T cell (CD8+ ), NK cell (CD16+ /CD56+ ), and B cell (CD19+ ) were analyzed, and CD4/CD8 ratios were calculated...

Plasmacytoid dendritic cells (pDCs) are crucial for control of chronic hepatitis B (CHB) virus infection. In this study, we evaluated the frequencies of pDCs and expression of functional molecules on pDCs in patients treated with PEG-IFN-α-2a or entecavir (ETV) and investigated changes during treatment. The mean fluorescence intensity of CD86 (CD86MFI) on the surface of pDCs and frequencies of pDCs and CD86+ pDCs in peripheral blood were measured. Compared with baseline, CD86+ pDC% and CD86MFI increased obviously after PEG-IFN-α-2a treatment for 12 and 24 weeks...

Vaccination with whole-cell or acellular (Ac) vaccines has been very effective for the control of pertussis. The immune response to Ac vaccines has been generally associated with a shift toward the Th2 profile. In the present study, overlapping recombinant fragments of filamentous hemagglutinin (FHA) and pertactin (PRN) were produced in Escherichia coli. BALB/c mice were immunized with recombinant FHA and PRN together with the native pertussis toxin and alum or CpG as adjuvant. Immunized mice were subsequently aerosol challenged with Bordetella pertussis...

Interleukin (IL)-4 is generally thought to promote tumor cell growth and inhibit apoptosis. However, its role in characteristics of monocytic leukemia cells was rarely reported. In this study, we assessed the role of IL-4 in tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) sensitivity of human monocytes. After incubation with IL-4 for 24 h, death receptor 4 (DR4) was significantly increased without downregulation of TRAIL decoy receptors and antiapoptotic proteins in THP-1 monocytes, and human primary monocytes and U-937 cells also exhibited increased TRAIL-induced apoptosis compared with control...

Chronic elevation of interferon (IFN)-response genes (IRG) in a subset of patients with systemic immune-dysregulatory diseases, including the Mendelian Type-I IFN-mediated autoinflammatory diseases and some autoimmune diseases suggest a causative role of excessive IFN signaling in the disease pathogenesis and as target for treatment. We developed a 28-IFN response gene scoring system to calculate either a standardized or geomean score by customizing a NanoString assay to quantify the expression of putative IRGs...

The antiviral cytokine interferon-alpha (IFN-α) plays a critical role in the innate immune system. Previous studies have shown that recombinant chicken IFN-α inhibits avian influenza virus (AIV) replication in vivo; however, the antiviral effect of recombinant duck IFN-α (rDuIFN-α) on highly pathogenic AIV remains unknown. In this study, the duck IFN-α gene was cloned, expressed, and purified. The antiviral effects of the resulting rDuIFN-α were further evaluated in vitro and in vivo. Our results showed that rDuIFN-α inhibited the replication of vesicular stomatitis virus (VSV) and AIV in duck embryo fibroblasts in vitro, with antiviral activities against VSV and AIV of 2...

In this study, preoperative serum levels of insulin-like growth factor 1 (IGF-1) were determined in 216 hepatocellular carcinoma (HCC) patients who underwent hepatic resection to investigate a possible contribution of IGF-1 to the increased risk for HCC recurrence and mortality. During January 2010 and December 2013, 216 HCC patients receiving hepatectomy were recruited. The primary endpoint was the HCC recurrences within the 3-year follow-up. The secondary endpoint was all-cause mortality. The multivariate analyses with Cox regression model were applied to explore the clinical significance of IGF-1 serum levels and associated parameters on death and recurrence of HCC patients...

Transfusion of packed red blood cells (PRBCs) modulates patients' immune responses and clinical outcomes; however, the underpinning mechanism(s) remain unknown. The potential for PRBC to modulate myeloid dendritic cells (mDC) and blood DC antigen 3 was assessed using an in vitro transfusion model. In parallel, to model processes activated by viral or bacterial infection, toll-like receptor agonists polyinosinic:polycytidylic acid or lipopolysaccharide were added. Exposure to PRBC upregulated expression of CD83 and downregulated CD40 and CD80 on both DC subsets, and it suppressed production of interleukin (IL)-6, IL-8, IL-12, tumor necrosis factor-α, and interferon-gamma-inducible protein-10 by these cells...

Interleukin (IL)-27 is a pleiotropic cytokine that regulates multiple aspects of innate and adaptive immunity, but whose role in immune protection of the female reproductive tract is unknown. Although not constitutively expressed by human uterine epithelial cells and fibroblasts in culture, IL-27 secretion was upregulated after treatment with the viral ligand poly (I:C) in a type I interferon (IFN)-dependent manner, with higher levels measured in fibroblasts than epithelial cells. Estradiol increased poly (I:C)-induced IL-27 production by fibroblasts, but not epithelial cells...

Hepatitis C virus (HCV) treatment is aiming to cure and prevent the development, progression of fibrosis, and related complications. Interferon-based therapy was claimed to reduce or even reverse fibrosis. Although direct-acting agents have a better cure rate, we still lack the knowledge of their effect on fibrosis regression. We aim to assess fibrosis regression in direct-acting agents compared with interferon-based treatment regimens in the treatment of chronic HCV patients. The 204 chronic HCV patients were divided into 3 groups; group 1(N = 68) received Peg-IFN and ribavirin, group 2 (N = 69) received sofosbuvir and ribavirin, and group 3 (N = 67) received Peg-IFN, ribavirin, and sofosbuvir...

Hepatitis C virus (HCV) is a global health problem, with an estimated prevalence of >185 million infections worldwide. About 399,000 people die every year because of HCV-associated liver complications such as liver cancer, liver cirrhosis, and hepatocellular carcinoma. Pakistan has the second-highest prevalence of HCV. The treatment of this life-threatening disease has always been a challenge, but the recent development of direct acting antivirals (DAAs) has offered hope to so many patients with this infection...

The development of the T- and natural killer (NK) cell growth factor IL-2 has been a sentinel force ushering in the era of immunotherapy in cancer. With the advent of clinical grade recombinant IL-2 in the mid-1980s, oncologists could for the first time directly manipulate lymphocyte populations with systemic therapy. By itself, recombinant IL-2 can induce clinical responses in up to 15% of patients with metastatic cancer or renal cell carcinoma. When administered with adoptively transferred tumor-reactive lymphocytes, IL-2 promotes T cell engraftment and response rates of up to 50% in metastatic melanoma patients...

Infection with dengue virus (DENV) can lead to a wide spectrum of clinical presentations, ranging from asymptomatic infection to death. It is estimated that the disease manifests only in 90 million cases out of the total 390 million yearly infections. Even though research has not yet elucidated which are the precise pathophysiological mechanisms that trigger severe forms of dengue, the infection elicits a critical immune response significant for dengue pathogenesis development. Understanding how the immune response to DENV is established and how it can resolve the infection or turn into an immunopathology is of great importance in DENV research...
