زمینه و اهداف: بکارگیری از سلولهای دندریتیک به عنوان ادجوانت های سلولی یکی از اهداف ایمونوتراپی سرطان را فراهم می نماید. ما در این تحقیق اثر ایمونوتراپی با سلولهای دندریتیک cd8?+بار شده به تومور لیزات شوک حرارتی را مورد بررسی قرار دادیم. مواد و روش ها: موشهای balb/c، ده روز قبل ازایمونیزاسیون با سلولهای دندریتیک cd8?+، با تزریق رده سلولی فیبروسارکوما wehi-164)) به صورت زیر پوستی مبتلا به توم...
Background: Job stressors in managers are progressively affecting and destroying their immune systems. The relationship between hardiness, stress and immune system is important for mental health. This study was designed to determine the resources in managers against stress, resources herein designated as “hardiness” and “social support". Also in this research, the correlation between hardiness,...
background: lymphocyte subsets enumeration is considered prominent in the management of primary and acquired immunodeficiency disorders. because of local variations due to race, age, gender, and environmental conditions on lymphocyte subsets, and to improve the accuracy of interpretation of laboratory findings, reference intervals must be determined in every population. objective: to establish ...
background: cd4+ and cd8+ t cells are the main types of lymphocytes in cell-mediated immunity and play a central role in the induction of efficient immune responses against tumors. the frequencies of t cell subtypes in the peripheral blood and tumor tissues, and draining lymph nodes (dln) can be considered as useful markers for evaluation of the immune system in cancers. methods: in this study,...

background lichen planus is a disease with unknown etiology that affects the skin and the mucous membranes. immune dysregulation in the pathogenesis of oral lichen planus (olp) is well-known phenomenon. objectives in this study, we compared the levels of the peripheral blood t lymphocytes between patients with olp and control group. patients and methods in this study, 32 and 16 patients respect...
Objective(s): To investigate the systemic and local immune status of two surgical rat models of sciatic nerve injury, a crushed sciatic nerve, and a sciatic nerve transection Materials and Methods:Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: sham-operation (control group), sciatic nerve crush, and sciatic nerve transaction. Sciatic nerve surgery was perfor...
This study was conducted to investigate the role of cell immunity in adults suffering from chronic sinusitis who referred to Rasoul-e-Akram Hospital for endoscopic sinus surgery. CD3, CD4, CD8 & CD4/CD8 ratio in sinus mucosa of serum IgE level were all measured in the patients. The three studied groups were: chronic sinusitis with high serum IgE(28 cases), chronic sinusitis with nor...
Abstract Introduction/Objective T-cell large granular lymphocytic leukemia (T-LGL) is a lymphoma with persistently increased lymphocytes in peripheral blood. The majority of T-LGL associated CD8+ T-cells. However, the CD4+ variant uncommonly seen. Methods/Case Report patient 49-year-old female history diabetes mellites and anemia who presented shortness breath, lower extremities edema, fatigue....
