Macrophage Immune Response Suppression by Recombinant Mycobacterium tuberculosis Antigens, the ESAT-6, CFP-10, and ESAT-6/CFP-10 Fusion Proteins
Background: Macrophage immune responses are affected by the secretory proteins of Mycobacterium tuberculosis (Mtb). This study aimed to examine the immune responses of macrophages to Mtb secretory antigens, namely ESAT-6, CFP-10, and ESAT-6/CFP-10.Methods: THP-1 cells (a human monocytic cell line) were cultured and differentiated to macrophages by phorbol 12-myristate 13-acetate. The cytotoxici...
متن کاملQuantiation of IL-4, IL-10 and IFN- Genes Expression after Immunization of Mice with CFP-10 and ESAT-6 Containing Vectors
Background: Tuberculosis is a disease with high morbidity, caused mainly by Mycobaterium tuberculosis (M.tb.). DNA vaccines show a promising future due to their unique advantages over conventional methods. The early-secreted antigen target (ESAT)-6 and culture filtrate protein (CFP)-10 of M.tb. antigens have been identified as vaccine candidates against Mycobacteria and used as subunit vaccines...
متن کاملConstruction of Eukaryotic Expression Vectors Encoding CFP-10 and ESAT-6 Genes and Their Potential in Lymphocyte Proliferation
Background: Mycobacterium (M.) bovis is the agent of bovine tuberculosis (TB) in a range of animal species, including humans. Recent advances in immunology and the molecular biology of Mycobacterium have allowed identification of a large number of antigens with the potential for the development of a new TB vaccine. The ESAT-6 and CFP-10 proteins of M. bovis are important structural and function...
متن کاملIFN-γ and IL-2 Responses to Recombinant AlaDH against ESAT-6/CFP-10 Fusion Antigens in the Diagnosis of Latent versus Active Tuberculosis Infection
Background: Discriminating latent tuberculosis infection (LTBI) from active TBI may be challenging. The objective of this study was to produce the recombinant L-alanine dehydrogenase (AlaDH) antigen and evaluate individuals with LTBI, those with active TBI, and uninfected individuals by enzyme-linked immunospot assay (ELISPOT) in order to distinguish LTBI from active TBI.Methods: This explorato...
متن کاملطراحی و ساخت پلاسمید حاوی کاست بیانی فیوژن پروتئین CFP-10، ESAT-6 مایکوباکتریوم توبرکولوزیس
زمینه و اهداف: در قرن گذشته تنها روش تشخیص عفونت نهفته مایکوباکتریوم توبرکولوزیس آزمایش پوستی توبرکولین بود. این آزمایش در بیماران آلوده با دیگر مایکوباکتریوم ها و در افراد واکسینه با BCG نتایج مثبت کاذب دارد. لذا، لزوم روش های تشخیصی کارآمد، سریع و دقیق مطرح می شود. دو آنتی ژن CFP-10و ESAT-6 در تمام مایکوباکتریوم های پاتوژن وجود دارد ولی در سویه های مولد واکسن BCGو مایکوباکتریوم های فرصت ط...
متن کاملExpression and Purification of Recombinant Mycobacterium Tuberculosis (TB) Antigens, ESAT-6, CFP-10 and ESAT- 6/CFP-10 and Their Diagnosis Potential for Detection of TB Patients
BACKGROUND One of the most widely used methods to detect tuberculosis (TB) infection is the tuberculin skin test (TST). The completion of Mycobacterium tuberculosis (M. tuberculosis) genome sequence has led to identification of several antigens that can be utilized for accurate diagnosis and control of TB. The aim of this study was to purify the recombinant M. tuberculosis antigens for the eval...
