Unmethylated cytosine-phosphorothioate-guanine oligodeoxynucleotides (CpG-ODNs) exhibit potent immunostimulating activity by binding with Toll-like receptor 9 (TLR9) expressed on antigen-presenting cells. Here, we show that CpG-ODN encapsulated in cationic liposomes (CpG-liposomes) improves its incorporation into CD11c(+) dendritic cells (DCs) and induces enhanced serum interleukin (IL)-12 leve...
سرطان پستان شایع ترین سرطان در زنان ایرانی است. تومورهای پستان بر اساس بیان گیرنده استروژن آلفا (er) به دو گروه er منفی و مثبت تقسیم می شوند.این طبقه بندی به انتخاب مسیر درمانی بیماران کمک می کند، بطوریکه بیماران مبتلا به تومورهای پستان نوع er مثبت با روش های مبتنی بر هورمون درمانی (مانند درمان با داروی تاموکسی فن) درمان می شوند. تومورهای er منفی به هورمون درمانی پاسخ نمی دهند. با توجه به ماهیت...
Unmethylated CpG dinucleotides in bacterial DNA or synthetic oligodeoxynucleotides (ODNs) are known as potent activators of the immune system and inducers of several Th1-associated immunomodulatory cytokines. We therefore investigated whether such a CpG-containing ODN (CpG ODN) given mucosally in the female genital tract could enhance innate immunity and protect against genital herpes infection...
Introduction: Among the factors that may be associated with the re-expression gamma-globin in adults is the methylation pattern of the promoter region. The study aimed to determine the association between promoter methylation pattern of the gamma-globin gene in the carriers and affected beta-thalassemia individuals and its expression levels. Methods: This study has been done as a case control-...
BACKGROUND Cytosine-phosphate-guanine (CpG) oligodeoxyribonucleotides (ODNs), which induce signaling via Toll-like receptor 9, have recently been suggested to enhance sensitivity to traditional therapies, including chemotherapy, in certain cancer cell lines. This study aimed to define the dose-effect relationship for CpG ODN 1826 in increasing radiosensitivity and its impact on immune function ...
BACKGROUND Bacterial infections in the genital tract frequently result in morbidity through a variety of inflammation based symptoms. One component of the bacteria that may trigger host inflammatory response is their DNA. CpG motifs in this DNA are known targets for Toll-like receptor 9 (TLR9), which is a pathogen-recognition receptors focusing on CpG DNA. The activation of TLR9 induces the NF-...
Unmethylated CpG dinucleotides in particular base contexts (CpG-S motifs) are relatively common in bacterial DNA but are rare in vertebrate DNA. B cells and monocytes have the ability to detect such CpG-S motifs that trigger innate immune defenses with production of Th1-like cytokines. Despite comparable levels of unmethylated CpG dinucleotides, DNA from serotype 12 adenovirus is immune-stimula...
PURPOSE Stimulation of toll-like receptor-9 (TLR9) by CpG oligodeoxynucleotides (CpG) has been shown to counteract the immunosuppressive microenvironment and to inhibit tumor growth in glioma models. Because TLR9 is located intracellularly, we hypothesized that methods that enhance its internalization may also potentiate its immunostimulatory response. The goal of this study was to evaluate car...
CpG oligodeoxynucleotides (CpG ODNs) stimulate immune cells via the Toll-like receptor 9 (TLR9). In this study, we have investigated the effects of CpG ODNs on latent human immunodeficiency virus (HIV) infection in human T cells. Treatment of the latently infected T cell line ACH-2 with CpG ODNs 2006 or 2040 stimulated HIV replication, whereas no effects were evident when ODNs without the CpG m...
هدف: اندازه گیری درست دامنه حرکتی ناحیه کمر هم در ارزیابی بیماران و هم در سنجش اثر درمان های مختلف توانبخشی از ارزش بالایی برخوردار است. هدف مطالعه فوق بررسی تکرارپذیری تست دو بار اصلاح شده شوبر (modified-modified schober's technique) در اندازه گیری دامنه حرکتی ناحیه کمر توسط آزمون گر واحد می باشد. روش بررسی: در یک مطالعه متدولوژیک، دامنه حرکتی ناحیه کمر (خم شدن به جلو و عقب) ۳۸ فرد سالم (...
