Background & Objectives: Interaction of cytomegalovirus glycoprotein B with toll-like receptors of dendritic cells leads to early signaling and innate immune responses. The aim of this study is to evaluate the effects of cytomegalovirus glycoprotein B on the maturation and function of monocyte-derived dendritic cells in treated groups in comparison with control groups. Materials & Methods: Bloo...
Background and Objective: Chimeric antigen T cell receptors provide a good approach for adoptive immunotherapy of cancer. In this new kind of chimeric T cell receptor, nanobodies are replaced as variable fragment of T cell receptor. Nanobodies (VHH) are the smallest fragments of antibodies that have great homology to human VH and low immunogenic potential. VHH-hing-CD28-CD3و construct was made ...
Efficient vaccination can be achieved by injections of in vitro transcribed mRNA (ivt mRNA) coding for antigens. This vaccine format is particularly versatile and allows the production individualised vaccines conferring, T-cell immunity against specific cancer mutations. The CDR3 hypervariable regions immune receptors (T-cell receptor, TCR or B-cell BCR) context T- leukaemia lymphoma are target...
introduction: over expression of selected peptide receptors in human tumors has been shown to represent clinically relevant targets for cancer diagnosis and therapy. the aim of this work was to investigate neuropeptide y (npy) as a new radiopharmaceutical for diagnosis of breast cancer. methods: a neuropeptide y analogues with y1 receptor preference and agonistic properties was synthesized by s...
T lymphocytes (T cells) are the major mediators of adaptive immune response. They detect pathogens primarily via interaction their cell receptor (TCR) with cognate pathogen-derived peptide displayed in context MHC on infected cell. A critical step activation is formation immunological synapse, a specialized cell–cell conjugate interface between and cell, where massive TCR-induced actin remodeli...
human epidermal growth factor receptor-2 (her-2) as a new prognostic and predictive factor has been believed as an essential measurement in breast carcinoma. about 280 articles were reviewed and 115 were referred in this review article on her-2. her-2 is an oncoprotein epidermal growth factor receptor produced by a so-called cell surface oncogene. overexpression results in aggressive behavior, ...
we have reviewed the medical records of 40 patients with disseminated (bacille calmette-guerin) bcg from 1996 to 1999 in the immunology department of the children hospital, medical center, tehran university. these patients are divided in to 3 groups: 1. patients who had disseminated (bacille calmette-guerin) bcg after vaccination and their diagnosis was chronic granulomatous disease. 2. patient...
Complement peptide receptors (nomenclature as agreed by the NC-IUPHAR subcommittee on [113]) are activated endogenous ~75 amino-acid anaphylatoxin polypeptides C3a and C5a, generated upon stimulation of complement cascade. C5a exert their functions through binding to (C3a receptor, receptor 1 2), causing cell recruitment triggering cellular degranulation that contributes local inflammation.
Background and Objectives: Alzheimerchr('39')s disease (AD) is a neurodegenerative disease which is marked by impaired cholinergic function and decreased nicotinic acetylcholine receptor (nAChRs) density. nAChRs are important mediators of cholinergic signaling in modulation of learning and memory function. In Alzheimer hippocampus is particularly vulnerable to specific degenerative processes an...
background: precursor b-acute lymphoblastic leukemia (precursor b-all) oc-curs due to the uncontrolled proliferation of b-lymphoid precursors arrested at a par-ticular stage of b-cell development. precursor-b-all is classified mainly into pro-b-all, common-all and pre-b-all. the common acute lymphoblastic antigen cd10 is the marker for common-all. objective: this study was aimed to examine the ...
