ige-mediated cell signaling, induced by cross-linking of high affinity receptor for ige (fcεri) in the presence of antigen (ag), is a well known mechanism described for mast cell activation in allergy and hypersensitivity reactions, which induces a spectrum of cellular responses such as secretion and up-regulation of cell surface fcεri. although for several years ige binding to fcεri was ...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
Abstract Mast cells play a critical role in the effector phase of immediate hypersensitivity and allergic reactions. Propolis exerts multiple biological effects exhibits immunomodulatory antioxidant properties. However, its antidinitrophenyl (DNP) immunoglobulin E (IgE)-activated mast has not been investigated. In this study, we examined mechanism underlying inhibitory effect propolis (Unibee p...
Background & Aims: Schizophrenia and Major Depressive Disorder (MDD) are severe mental disorders and disturbances of immunity system are seen in their pathogenic process. Thus, in schizophrenia both general and specific components of immune system are disturbed. In MDD immunity system also changes. Numerous studies show that when depressed patients are exposed to allergen pollens, elevation of ...
Objective: Previous studies indicated anti-inflammatory effects for Portulaca oleracea in various inflammatory disorders. In this study, the effects of P. oleracea on bronchoalveolar lavage fluid (BALF) levels of total protein (TP), Phospholipase A2(PLA2) and IgE in sensitized rats were examined. Materials and Methods: Male rats were randomly divided into six groups namely, control (group C), s...
Background: Decay of vaccine–induced antibody titres without boosting of the wild measles virus has been well documented. Revaccination against measles has reduced the prevalence of the disease worldwide. Revaccination may cause IgE induced anaphylaxis. Objective: To study measles IgG antibody in revaccinated populations and its relation to IgE induced hypersensitivity. Methods: Blood samples w...
Pulmonary hypertension (PH) is a severe cardiopulmonary disease characterized by pulmonary vascular remodeling. Immunoglobulin E (IgE) known to participate in aortic remodeling, but whether IgE mediates unknown. In the present study, we found serum elevation arterial (PAH) patients, hypoxia-induced PH mice and monocrotaline-induced rats. Neutralizing with an anti-IgE antibody was effective prev...
Background and Aim: Allergy to some food products is a usual affair which appears to be caused by immunologic and non immunologic reactions. One of the most important factors generating these reactions is mediating the IgE which can cause anaphylaxis. Additionally one of the most renowned allergens is wheat. However the best method for curing these patients is avoiding from allergen, modern app...
Resident mouse peritoneal macrophages release the slow-reacting substance leukotriene C (LTC) on exposure to particulate IgE immune complexes. Because these cells lose their responsiveness to an IgE stimulus after 4 h in culture, maximum release of 20:4 metabolites is observed before this time. However, a similar diminution in 20:4 metabolism was not observed with a zymosan stimulus. Freshly ex...
