Apelin receptor antagonist boosts dendritic cell vaccine efficacy in controlling angiogenic, metastatic and apoptotic-related factors in 4T1 breast tumor-bearing mice.

Apelin/APJ axis plays a critical role in cancer progression, thus its targeting inhibits tumor growth. However, blocking of Apelin/APJ axis in combination with immunotherapeutic approaches may be more effective. This study aimed to investigate the effects of APJ antagonist ML221 in combination with a DC vaccine on angiogenic, metastatic and apoptotic-related factors in a breast cancer (BC) model.

Cimetidine and Ibuprofen Modulate T Cell Responses in a Mouse Model of Breast Cancer.

Cimetidine and ibuprofen exhibit immunomodulatory effects as an antagonist of histamine H2 receptor, and a cyclooxygenase inhibitor, respectively. Here, the effects of cimetidine and ibuprofen on some effector T cell-related parameters were investigated using a breast cancer (BC) model. BC was established in Balb/c mice using the 4T1 cell line.

Modulatory Effects of Metformin Alone and in Combination with Cimetidine and Ibuprofen on T Cell-related Parameters in a Breast Cancer Model.

Metformin, cimetidine, and ibuprofen separately exhibit immunomodulatory and anti-tumorigenic effects. Herein, the impacts of metformin alone and in combination with cimetidine/ibuprofen on some Th1- and regulatory T (Treg) cell-related parameters were evaluated using a breast cancer (BC) model. For establishing the BC model, four groups of Balb/c mice were challenged with the carcinoma cell line.

Zingerone improves the immune responses in an animal model of breast cancer.

Objectives: The potent anti-tumorigenic effects were attributed to ginger and there are some reports regarding the anti-cancer and immunomodulatory properties ginger-derived components. This study aimed to investigate the effects of zingerone on some immune-related parameters in an animal model of breast cancer.

Methods: The breast cancer was established in female BALB/c mice using a carcinogenic 4T1 cell line.

Role of maternal interleukin-8 (IL-8) in normal-term birth in the human.

Cytokines are the main factors involved in the normal functions of the placenta and delivery process. The aim of this project was to compare serum levels of interleukin-8 (IL-8), IL-6, tumour necrosis factor α (TNF-α) and transforming growth factor β (TGF-β) in term and prolonged-pregnancy mothers and their neonates. This study was performed on 240 participants including 60 term and prolonged-pregnancy neonates and their corresponding mothers.

SPECIFIC SERUM IMMUNOGLOBULIN G AGAINST CHLAMYDIA PNEUMONIAE IN HEALTHY CHILDREN AND ADULTS IN SOUTH-EAST OF IRAN.

Background: Chlamydia pneumoniae (C. pneumonia) is an obligate intracellular bacterium and recognized as a risk factor for several diseases such as asthma, atherosclerosis and arthritis. The aim of this study was to determine the seroprevalence of C.

The persistence of anti-HBs antibody and anamnestic response 20 years after primary vaccination with recombinant hepatitis B vaccine at infancy.

Hepatitis B (HB) vaccine induces protective levels of antibody response (anti-HBs≥10 mIU/mL) in 90-99% of vaccinees. The levels of anti-HBs antibody decline after vaccination. The aim of this study was to evaluate the persistence of anti-HBs antibodies and immunologic memory in healthy adults at 20 years after primary vaccination with recombinant HB vaccine.

Helicobacter pylori seropositivity in patients with type 2 diabetes mellitus in south-east of Iran.

It has been also reported that that H. pylori infection may be responsible for some endocrine disorders, such as autoimmune thyroid diseases, diabetes mellitus and primary hyperparathyroidism. H.

Higher serum levels of rheumatoid factor and anti-nuclear antibodies in helicobacter pylori-infected peptic ulcer patients.

Objectives: H. pylori infection has been associated with some autoimmune disorders. The aim of this study was to evaluate the serum concentrations of rheumatoid factor and anti-nuclear antibodies in H.

Lower circulating levels of chemokine CXCL10 in Helicobacter pylori-infected patients with peptic ulcer: Influence of the bacterial virulence factor CagA.

Background And Objectives: Alterations in CXCL10 (a Th1 chemokine) expression have been associated with various diseases. The aim of this study was to evaluate the serum CXCL10 levels in H. pylori-infected patients with peptic ulcer (PU), H.

Circulating interleukin-27 levels in Helicobacter pylori-infected patients with gastric or duodenal ulcers, independent of the bacterial cytotoxin-associated gene A virulence factor.

Objective: The aim was to evaluate the interleukin (IL)-27 levels in Helicobacter pylori (H. pylori)-infected patients with gastric ulcer (GU) or duodenal ulcer (DU) and to determine its association with H. pylori virulence factor cytotoxin-associated gene A (CagA).

High serum levels of rheumatoid factor and anti-phosphatidylserine antibody in patients with ischemic heart disease.

Background: Immunopathological and inflammatory processes play important roles in the initiation and development of Ischemic Heart Disease (IHD).

Objective: The aim of this study was to evaluate the serum levels of several autoantibodies including rheumatoid factor (RF), anti-nuclear antibodies (ANA), anti-small nuclear ribonucleoprotein (anti-Sm), anti-phosphatidylserine (anti-PS) and anti-cardiolipin (anti-CL) antibodies in patients with IHD.

Methods: A total of 120 patients with IHD with acute myocardial infarction (AMI; n=60) or unstable angina (UA; n=60) and 60 sex- and age-matched healthy subjects were enrolled in this study.

Cigarette smoke-exposed saliva suppresses cellular and humoral immune responses in an animal model.

Objective: To evaluate the effects of cigarette smoke (CS)-exposed saliva on cellular and antibody responses in an animal model.

Methods: The stimulatory and non-stimulatory saliva samples were collected from 10 healthy subjects and were then exposed to CS for 20 or 80 minutes. The CS-exposed saliva samples were administrated intraperitoneally (i.

Association of the CagA status of Helicobacter pylori and serum levels of interleukin (IL)-17 and IL-23 in duodenal ulcer patients.

Objective: It has been reported that the cytotoxin-associated gene A (cagA+) H. pylori strains induce severe gastric mucosal inflammation. The aim of this study was to investigate the association of the virulence factor CagA with IL-17 and IL-23 serum levels in duodenal ulcer (DU) patients and H.

Serum levels of interleukin (IL)-13, IL-17 and IL-18 in patients with ischemic heart disease.

Objective: It has been reported that the cytokines play an important role in the pathogenesis of cardiovascular diseases. The aim of this study was to evaluate the serum levels of interleukin (IL)-13, IL-17 and IL-18 in patients with ischemic heart disease (IHD) and also to clarify their association with traditional risk factors of disease.
