it has been demonstrated that natural killer (nk) cells play a role in regulation of autoimmunity. they play a protective role in several rodent disease models. in this study we aimed to compare the immunophenotypic features of nk cells in ankylosing spondylitis (as) with normal subjects with regard to cd56 and cd16 molecules. this study was carried out on 30 as patients and 33 normal volunteer...
سلولهای کشنده طبیعی (nk) بخشی از ایمنی ذاتی هستند که بعنوان اولین خط دفاعی، نقش بارزی در از بین بردن سلولهای سرطانی و سلولهای آلوده به ویروس دارند. هدف ما از این پژوهش بررسی تأثیرات ناشی از تغییر در ظاهر شدن مولکولهای hla کلاس i بر سطح یاخته های سرطانی، در میزان حساسیت به عملکرد سایتوتوکسیسیته سلولهای nk است. در این بررسی یاخته های سرطانی رده mda-mb-468 مشتق شده از آدنوکارسینومای پستان انسان، ب...
روش های مانده ای دسته ای از روش های تکراری می باشند که جهت حل سیستم های خطی با ماتریس ضرایب تنک و بزرگ بکار می روند. نوعی از این روش مشهور به روش gmres از اهمیت فراوانی برخوردار است. در این پایان نامه روش مانده ای جدیدی تحت عنوان minres-nk را بر روی دسته ای از دستگاه های معادلات خطی با ماتریس ضرایب نرمال وقتی که طیف ماتریس روی یک منحنی درجه k قرار دارد بیان نموده و آن را با روش gmres مقایسه می ...
Background and Objectives: Tumor-infiltrating regulatory T (TI-Treg) cells perform the significant function in cancer immune escape. In this study, the third generation CAR construct was designed against human CD25 antigen, the significant cell surface biomarker of TI-Tregs. Methods: Initially, the construct of anti-CD25 CAR was designed. Using RNAfold web server, the RNA secondary structure wa...
ABSTRACT Natural Killer cells (NKs), are considered an important first line of defence and were originally defined by their ability to kill certain tumor cells and virally infected cells. Our aim is to study expression of HLA class-Ia on tumor cell lines and their susceptibility of NK cells. In this study MDA-MB-468 tumor cell line (NCB1, C208) That derived from human breast adenocarcino...
Peripheral T-cell lymphomas are a group of heterogeneous disorders and according to WHO classification, are categorized into nodal and extranodal forms. NK/T-cell lymphoma, nasal type, is a subtype of extranodal peripheral T-cell lymphoma and commonly presents as a midfacial destructive lesion. This disorder is more prevalent in Asia and South America and has a strong association with Epstein B...
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 ...
background: natural killer (nk) cells are the effector cells of innate immunity that respond to infection and tumor. interactions between killer cell immunoglobulin like receptors (kir) and human leukocyte antigen (hla) class i molecules regulate nk cells responses to eliminate infected and transformed cells. objective: to investigate the impact of kir genes, hla ligand genes, and kir-hla combi...
Background: NK (natural killer) and NKT (natural killer T) cells, as components of innate immune system, play a crucial role in tumor progression and dissemination. Objective: To investigate the percentages of NK cells, NKT cells, iNKT (invariant natural killer T) cells, total T lymphocytes as well as activated T lymphocytes, in tumor draining lymph nodes (TDLN...
