The cancer-immune interplay and its role on the evolution of NSCLC might be disclosed through detection local systemic cues. Aim: To determine whether peripheral blood (PB) immune profiles may mirror clinically relevant tumor microenvironmental (TIME) features in resected patients. Tissue PB samples were prospectively collected at surgery from 80 consecutive stage I-IIIA cases. immunohistochemi...
splenic hamartoma is an unusual accidental finding with non-neoplastic feature that may be incidentally diagnosed because of its compression effect on surrounding organs. the predominant pathological feature leading diagnosis is circumscribed, un-encapsulated bulging nodules with focal fibrosis or cyst. the histopathological feature of splenic hamartoma is the positivity for cd8, and occasional...
Bovine theileriosis is a tick-borne disease caused by obligate intracellular parasites related to the genus Theileria. Cellular immune responses protect cattle against pathogens through the activation of immune cells. Nowadays, live, attenuated vaccine of Theileria annulata (T. annulata) is being produced in Iran and is recommended for active cattle immunization. Detection of the immunogenic a...
Objective(s): In this study, we aimed to investigate the effects of anti-Fas ribozyme on the apoptosis of T lymphocytes (T cells) in mice model with chronic obstructive pulmonary disease (COPD). Materials and Methods: Male 6-week-old C57BL/6 mice were used to establish the COPD model by exposure to cigarette smoke. The COPD mice were sacrificed for spleen dissection and T cell isolation. T cell...
Background: Herpes simplex virus type 1 is one of the most common viruses among human population. Studies demonstrate the essential role of cell mediated immunity, especially CD8+ T cells, in prevention and clearance of HSV1. Objective: It is of great importance to improve our knowledge about the kinetics of CTL responses to primary and secondary HSV-1 infection. Methods: Using a sensitive tech...

چکیده: بیماری سل بوسیله مایکوباکتریومهای بیماریزا از جمله mycobacterium tuberculosis ایجاد می گردد. طبق گزارش who، بیش از یک سوم جمعیت جهان آلوده به این باکتری هستند که بیش از 90 درصد آنها بدون علامت می باشند. این افراد تحت عنوان latent tuberculosis یا افراد ltbi معرفی می گردند. در این پژوهش، سیستم ایمنی اکتسابی در افراد مبتلا به سل فعال و سل نهفته، مورد مقایسه و آنالیز قرار گرفت. پروفایل سای...
به نظر می رسد که ورزش با شدت متوسط سیستم ایمنی بدن را تحریک می کند، اما شواهد خوبی نیز وجود دارد که نشان می دهد تمرین شدید می تواند باعث تضعیف سیستم ایمنی شود. هدف تحقیق حاضر، مقایسه اثر یک جلسه تمرین فزاینده درمانده ساز هوازی توسط دست و پا بر پاسخ سلول های nk) cd16، cd56، cd16/56)و t) cd4، cd8، cd4/cd8) سیستم ایمنی دانشجویان پسر رشته تربیت بدنی دانشگاه شهید چمران اهواز بود. بدین منظور 20 آزمود...
Background: Thermal burn injuries impair the host defence system. Hence, in the present study, we aimed at investigating the changes in the number and phenotype of peripheral blood lymphocyte populations (T, B, and natural killer cells) and their subpopulations in patients with thermal burns and determining the relationships with different sizes of total body surface area (TBSA). ...
