The purpose of this study was to produce large scale of monoclonal antibody against CD20 in order to diagnostic application in leukemia and lymphomas disorders.

Methods: Hybridoma cells that produce monoclonal antibody against human CD20 were administered into the peritoneum of the Balb/c mice which have previously been primed with 0.

Inhibitory and cytotoxic activities of salvia officinalis L. Extract on human lymphoma and leukemia cells by induction of apoptosis.

Purpose: Salvia officinalis L., also known as Maryam Goli, is one of the native plants used to Persian medicinal herbs. Hence, the objective of this study was to examine the in vitro cytotoxic activities of a standardized crude methanol extracts prepared from Salvia officinalis L.

New approaches in immunotherapy of behçet disease.

Behçet Disease (BD) is an autoimmune disorder with recurrent ocular, vascular, central nervous system, articular, mucocutaneous, and gastrointestinal manifestations with unclear etiology and pathogenesis. The further characterization of inflammatory features of Behçet's disease may eventually lead to development of better treatment options. Clinical and laboratory observations suggested an important role of IL-17, IL-21 and neutrophil-mediated process in the pathogenesis of BD.

New insights into HLA class I association to Behçet's syndrome in Iranian Azari patients.

Behçet's syndrome (BS) is a chronic recurrent inflammatory disorder characterized by oral and genital ulcers and ocular inflammation. BS has a complex genetic etiology. To evaluate the influence of human leukocyte antigen (HLA) class I in BS susceptibility in Iranian Azari population, we studied 290 BS patients and 300 healthy controls.

Sensitive antibody-based CTCs detection from peripheral blood.

The detection of Circulating Tumor Cells (CTC) is a purpose in numerous oncology research fields. CTCs are disseminated from the original site from metastatic and primary tumors in the peripheral blood of breast, prostate, lung and colorectal cancer patients. Different characteristics of tumor cells have been applied to define enrichment methods through the differential expression of tumor-specific markers on the surface of the cells.

Tumor angiogenesis and anti-angiogenic therapies.

Angiogenesis, the development and growth of blood vessels, is a major topic of research which began in 1971 with Folkman's original hypothesis. Different mechanisms of blood vessel growth are sprouting and intussusceptive angiogenesis, vascular mimicry, and blood vessel cooption. Dis-regulated angiogenesis may result in numerous angiogenic diseases and is responsible for solid tumor growth and metastasis.

Future prospects of monoclonal antibodies as magic bullets in immunotherapy.

Monoclonal antibody therapy has become a critical component of clinical treatment procedure for a variety of indications. Therapeutic antibodies have made the transition from conception to clinical reality over the past two decades. Now, many of mAbs are being tested as adjuvant or first-line therapies to determine their efficacy in improving survival.

Behçet's syndrome in Iranian Azari people.

Behçet's Syndrome (BS) is a chronic recurrent multisystemic inflammatory disorder characterized by oral and genital ulcers, ocular inflammation. Behçet's syndrome has a complex genetic etiology. However, epidemiological studies recommend that genetic factors have a significant influence to its pathogenesis, alike to other autoinflammatory disorders.

Current challenges in metastasis: disseminated and circulating tumor cells detection.

Metastatic dissemination of the primary tumor is responsible for the majority of cancer-related morbidity and mortality. Detection of disseminated tumor cells in the bone marrow and circulating tumor cells in the peripheral blood is associated with early metastatic recurrence in cancer. Circulating tumor cells (CTCs) shed from the site of disease in metastatic or primary tumor that can be recognized and enriched in the peripheral blood of cancer patients.
