[ 1 ] - Differential WNT Gene Expression in Various Subtypes of Acute Lymphoblastic Leukemia

Background: Dysregulation of WNT signaling has been reported in many malignancies. Objective: This study was conducted to investigate the expression pattern of 14 members of the WNT gene family in different immunophenotypic subtypes of ALL. Methods: Semi-quantitative RT-PCR was performed on samples from 71 ALL patients and 36 age-matched healthy individuals. The ALL patients were categorized in...

[ 2 ] - Lymphocyte Cytotoxicity of oxLDL in Patients with Atherosclerosis

Background: Atherosclerosis, a chronic inflammatory disease of the vessel wall is characterized by local and systemic immune responses to a variety of antigens. Oxidized low-density lipoprotein (oxLDL) is considered as an important determining factor in the pathogenesis of atherosclerosis. Objective: The purpose of this study was to investigate the degree of peripheral blood mononuclear cells (...

[ 3 ] - Immunologic Basis and Immunoprophy-laxis of RhD Induced Hemolytic Disease of the Newborn (HDN)

RhD antigen is the most immunogenic and clinically significant antigen of red blood cells after ABO system. It has historically been associated with hemolytic disease of the newborn (HDN) which is now routinely prevented by the administration of polyclonal anti-D immunoglobulin. This management of HDN has proven to be one of the most successful cases of prophylactic treatment based on antibody ...

[ 4 ] - HLA-DRB1, DQA1 and DQB1 Alleles and Hap-lotypes Frequencies in Iranian Healthy Adult Responders and Non-Responders to Recombi-nant Hepatitis B Vaccine

Background: Different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis B (HB) vaccine do not produce protective levels of anti-HB antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (HLA) class-II alleles or haplotypes. Objectives: The present study was under-taken to determine the frequency of HLA class-II alleles in ...

[ 5 ] - Immunophenotypic Characterization of the Leukemic B-cells from Iranian Patients with Chronic Lymphocytic Leukemia: Association between CD38 Expression and Disease Progression

Background: Patients with B-cell chronic lymphocytic leukemia (B-CLL) have hetero-geneous clinical courses, thus several biological parameters need to be added to the cur-rent clinical staging systems to predict disease outcome. Recent immunophenotypic stud-ies performed mainly in Western populations have demonstrated the prognostic value of CD38 and ZAP-70 expression in B-CLL. Objectives: To i...

[ 6 ] - Expression Profile of Wnt Molecules in Leukemic Cells from Iranian Patients with Acute Myeloblastic Leukemia

Background: Wnt molecules play a key role in growth, proliferation and development of some embryonic and adult organs as well as hematopoietic stem cells. Wnt signaling pathways are aberrantly activated in many tumor types, including solid tumors and hematologic malignancies. Objective: To investigate the expression profile of a large number of Wnt genes in leukemic cells from Iranian patients ...

[ 7 ] - Immunogenicity of a Triple Diphtheria-Tetanus-Whole Cell Pertussis Vaccine in Iranian Preschool Children

Background: Immunization against diphtheria, tetanus and pertussis has been applied in Iran since 1950. WHO suggests periodical evaluation of effectiveness of the triple diphtheria-tetanus-whole cell pertussis (DTwP) vaccine, worldwide. Objectives: To determine the immunogenicity of locally manufactured DTwP vaccine administered to preschool children in a number of health centers of Tehran in 2...

[ 8 ] - Immunophenotypic Subtyping of Leukemic Cells from Iranian Patients with Acute Lymphoblastic Leukaemia: Association to Disease Outcome

Background: Immunophenotypic characterization of the leukemic cells has been widely used as a tool for diagnosis, classification, stratification and prognosis of leukaemia. Objective: To investigate the immunophenotypic subtype profiles of Iranian patients with acute lymphoblastic leukemia (ALL) and its association to disease outcome. Methods: In this study, a total of 60 Iranian patients with ...

[ 9 ] - Over-expression of Wilm’s Tumor Gene 1 (WT1) in Iranian Patients with Acute Myeloblastic Leukemia

Background: The Wilm’s tumor gene 1 (WT1) encodes a zinc finger transcription factor that is inactivated in a subset of Wilm’s tumors. It plays a crucial role in growth, proliferation and development of some embryonic and adult organs. WT1 is expressed as a tumor associated antigen (TAA) in various types of solid and hematopoietic malignancies and can be employed as a useful marker for targeted...

[ 10 ] - Measurement of Affinity Constant of Anti-human IgG Monoclonal Antibodies by an ELISA-based Method

Background: The affinity of an antibody to its antigen is a crucial parameter in its biological activity and performance of an immunoassay such as ELISA. Affinity of most IgG specific MAbs are often determined by methods which require labeling of either antigen or antibody, and are sometimes difficult to control, do not always lead to the expected signal and often result in immunological modifi...
