IL-10 and IL-12 Production in Response to Mycobacterium Tuberculosis Total Lipid Antigens in Multidrug-Resistant Tuberculosis
Background: Mycobacterium tuberculosis lipid antigens take part in pathogenicity of the bacterium but the response of monocytes/macrophages to these antigens in tubercu-losis is not well known. Objective: The aim of current investigation was to study the M. tuberculosis lipid antigens in tuberculosis pathogenesis. Methods: In the present study M. tuberculosis lipid antigens were extracted. Mono...
متن کاملImmune response to Mycobacterium tuberculosis in rats.
After intravenous injection into rats, both the attenuated strain R1Rv and the virulent strain H37Rv of Mycobacterium tuberculosis grow in the liver and spleen. However, the infected rats mount a specific immune response with great rapidity, giving a false impression of natural resistance to the tubercle bacillus. Adoptive immunity to tuberculosis was achieved by transferring thoracic duct cell...
متن کاملEvaluation of Human Serological Response to Recombinant TB10.4 Antigen of Mycobacterium tuberculosis
Introduction: Development of effective immunodiagnostic methods for detection of Mycobacterium tuberculosis infection is crucial. Serodiagnostic methods, based on antibody response to specific antigens could provide promising approaches for rapid, economical and easy to perform diagnostic tests which are crucial for tuberculosis (TB) control. In this study, the level of IgG antibody responses...
متن کاملComparative immune response to PE and PE_PGRS antigens of Mycobacterium tuberculosis.
Sequencing of the entire genome of Mycobacterium tuberculosis identified a novel multigene family composed of two closely related subfamilies designated PE and PE_PGRS. The major difference between these two families is the presence of a domain containing numerous Gly-Ala repeats extending to the C terminus of the PE_PGRS genes. We have used a representative PE_PGRS gene from M. tuberculosis, R...
متن کاملThe T-Cell Response to Lipid Antigens of Mycobacterium tuberculosis
T-cells recognize lipid antigens presented by dedicated antigen-presenting molecules that belong to the CD1 family. This review discusses the structural properties of CD1 molecules, the nature of mycobacterial lipid antigens, and the phenotypic and functional properties of T-cells recognizing mycobacterial lipids. In humans, the five CD1 genes encode structurally similar glycoproteins that recy...
