[ 1 ] - Islet Amyloid Polypeptide is not a Target Antigen for CD8+ T-Cells in Type 2 Diabetes
Background: Type 2 diabetes (T2D) is a chronic metabolic disorder in which beta-cells are destroyed. The islet amyloid polypeptide (IAPP) produced by beta-cells has been reported to influence beta-cell destruction. Objective: To evaluate if IAPP can act as an autoantigen and therefore, to see if CD8 + T-cells specific for this protein might be present in T2D patients. Methods: Peripheral blood ...
[ 2 ] - Immunoinhibitory Effect of Teuclatriol a Guaiane Sesquiterpene from Salvia mirzayanii
Background: Salvia mirzayanii, a native plant to Iran, is shown to have immunomodulatory effects on lymphocyte proliferation. Objective: To identify the bioactive immunomodulatory compound(s) present in S. mirzayanii. Methods: The crude extract was fractionated to five fractions in two steps using different solvents. The fractions were subjected to bioassay-guided fractionation. All the fractio...
[ 3 ] - Inhibition of Nitric Oxide Production and Proinflammatory Cytokines by Several Medicinal Plants
Background: A number of medicinal plants have been used to treat various immunological diseases. Nitric oxide (NO) has an important regulatory role in the various types of inflammatory processes. Objective: To investigate the NO modulatory activity of the extracts of several medicinal plants native to Iran including Dracocephalum kotschyi, Linum persicum, Dionysia termeana, Salvia mirzayanii, F...
[ 4 ] - Haussknechtia Elymatica: A Plant with Immunomodulatory Effects
Background: Plant extracts have been widely investigated for possible immunomodu-latory properties. Objective: To study the immunomodulatory functions of the metha-nol extract of Haussknechtia elymatica (Apioideae), an herb native to south-western Iran. Methods: Delayed type hypersensitivity (DTH) skin test and measurement of an-tibody titer after immunization with Sheep-RBC was performed. [3H]...
[ 5 ] - The Influence of Perforin Expression on the Sensitivity of LAK/NK Killing Against Various Tumor Target Cells
Background: Perforin is known to be important in cytolytic activity mediated by natural killer (NK) cells. Objective: To study the relationship between the efficiency of NK and lymphokine-activated killer (LAK) cells activity, and the expression of perforin and HLA class I molecules. Methods: LAK cells were generated by in vitro culturing of human peripheral blood lymphocytes (PBLs) in the ...
[ 6 ] - p53 Protein Expression and Its Relation to the Apoptotic Index in Prostate Adenocarcinoma
Background: Prostate cancer is one of the most commonly diagnosed cancers in males. Tumor suppressor gene p53 plays an important role in causing cell cycle arrest and allowing apoptosis to proceed. Objective: To investigate the expression of p53 protein and its relation to apoptosis and prostate cancer traditional prognostic indicators. Methods: In this study expression of p53 was examined in p...
[ 7 ] - MONOCLONAL ANTIBODIES TO HUMAN ALPHA-FETOPROTEIN
Alpha-fetoprotein (AFP), a serum glycoprotein belonging to the onco-developmental proteins group, serves as a marker both in cancer research and in studies concerning fetal development and fetal pathophysiology. Monoclonal anti-AFP antibodies are essential reagents in developing appropriate techniques for measurement of this protein. In this study, in order to produce anti-AFP monoclonal a...
[ 8 ] - Cloning, Expression and Characterization of Recombinant Human Fc Receptor Like 1, 2 and 4 Molecules
Background: The Fc receptor like (FCRL) molecules belong to the immunoglobulin (Ig) superfamily with potentially immunoregulatory <span style="font-va...
[ 9 ] - Modulation of in vitro proliferation and cytokine secretion of human lymphocytes by Mentha longifolia extracts
Objective: Mentha longifolia L. Hudson has been used in folk medicine for various purposes especially for its anti-inflammatory effects. Lymphocytes play a central role in development of inflammation. In the present study, we investigated the immunomodulatory effects of different extracts of M. longifolia on human peripheral blood lymphocytes (PBLs), as main players in development of inflammati...
