[ 1 ] - Detection of IL-20R1 and IL-20R2 mRNA in C57BL/6 Mice Astroglial Cells and Brain Cortex Following LPS Stimulation

Background: Astrocytes, which comprise ~90% of overall brain mass, are involved in brain immunity. These cells represent the non-professional class of CNS-resident APCs and may promote or inhibit CNS inflammation depending on the cytokines they secrete. IL-10 family of cytokines and their receptors, IL-20R1 and IL-20R2, may have a role in shifting astrocytes to a neuroprotective or neurodegener...

[ 2 ] - Immunogenicity of a New HIV-1 DNA Construct in a BALB/c Mouse Model

Background: Cell mediated immunity, especially cytotoxic T cell responses against HIV-1 infection, plays a critical role in controlling viral replication and disease progres-sion. DNA vaccine is a novel technology which is known to stimulate strong cellular immune responses. Many DNA vaccines have been tested for HIV infection but there is still no effective vaccine against this infection. Cons...

[ 3 ] - تاثیر اینترلوکین-27 بر بهبودی از بیماری انسفالومیلیت خودایمن در موش های C57BL/6

سابقه و هدف: مولتیپل اسکلروزیس (MS) و مدل حیوانی آن، انسفالومیلیت خود ایمن تجربی (EAE)، بیماری های التهابی مزمن تحلیل برنده میلین سیستم عصبی مرکزی می باشند. هدف از این مطالعه، بررسی اثرات پلاسمید کد کننده IL-27 بر وضعیت بیماری و برخی پارامترهای ایمونولوژیکی در موش های C57BL/6 مبتلا به EAE بود. مواد و روش ها: ژن IL-27 موشی در پلاسمید P240 کلون شد. 200 میکروگرم از پلاسمید نوترکیب حاصل (P240-mIL27...

[ 4 ] - انتقال ژن به سلول‌های بنیادی مزانشیمال موشی: بررسی مقایسه‌ای دو روش ویروسی و غیر ویروسی

    Background and Aims : Mesenchymal stem cells (MSCs) are attractive targets for cell and gene therapy, because they can differentiate into many cell lineages. Hence, finding an efficient and suitable method for transferring of genetic materials to these cells is very essential. In this study, we evaluated the efficiency of two methods of gene transferring, viral and nonviral, in transfection...

[ 5 ] - تأثیر تمرین هوازی پس از قرارگیری در معرض هوای آلوده به ذرات کربن سیاه بر بیان ژن TLR4 و TLR2 در بافت هیپوکمپ مغز موش‌های صحرایی

قرارگیری در هوای آلوده بر سیستم عصبی مرکزی تأثیرگذار است و به التهاب و تخریب عصبی منجر می‌شود. هدف از پژوهش حاضر بررسی تأثیر تمرین هوازی و هوای آلوده به ذرات کربن سیاه بر بیان mRNA ژن گیرندۀ شبه تول 2و 4 (TLR4 و TLR2 ) در هیپوکمپ مغز موش‌ها بود. 24 سر موش نر نژاد ویستار به‌طور تصادفی در چهار گروه الف) کنترل، ب) آلودگی، ج) تمرین و د) تمرین- آلودگی قرار گرفتند. موش‌های گروه‌های ب و د به مدت چهار ...

[ 6 ] - An HIV-1 Mini Vaccine Induced Long-lived Cellular and Humoral Immune Responses

Memory formation is the most important aspect of a vaccine which can guarantee long-lasting immunity and protection. The main aim of the present study was to evaluate the memory immune responses after immunization with a mini vaccine. Mice were immunized with human immunodeficiency virus-1 P24-Nef fusion peptide and then cellular and humoral immune responses were evaluated. In order to determin...

[ 7 ] - Preparation and Characterization of PLGA Nanoparticles Containing Plasmid DNA Encoding Human IFN-lambda-1/IL-29

During the 15 years since the discovery of type III human interferons [IFN-λ1(IL-29), IFN-λ2(IL-28A), and IFN-λ3(IL-28B)], numerous biological properties such as anticancer, antiviral, and immunomodulatory activities of this new IFN family have been investigated. Several studies have shown that the encapsulation of pcDNA with PLGA nanoparticles (NPs) protects them against DNase enzyme action an...
