Novel human recombinant antibodies against Mycobacterium tuberculosis antigen 85B

Novel human recombinant antibodies against Mycobacterium tuberculosis antigen 85B

BACKGROUND Tuberculosis is the leading cause of death due to bacterial infections worldwide, mainly caused by Mycobacterium tuberculosis. The antigen 85 complex comprises a set of major secreted proteins of M. tuberculosis, which are potential biomarkers for diagnostic. RESULTS In this work, the first human single chain fragment variable (scFv) antibodies specific for the tuberculosis biomark...

Evaluation 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...

Efficacy of recombinant bacille Calmette-Guérin vaccine secreting interleukin-15/antigen 85B fusion protein in providing protection against Mycobacterium tuberculosis.

Protection against Mycobacterium tuberculosis not only depends on CD4+ T helper type 1 (Th1) cells but, also, on CD8+ T cells. Interleukin (IL)-15 has an important function in the maintenance of memory CD8+ T cells. In the present study, we examined the efficacy of recombinant Mycobacterium bovis bacille Calmette-Guérin (rBCG) secreting fusion protein antigen (Ag) 85B murine IL-15 (rBCG-Ag85B-I...

Aerosol Delivery of Recombinant Antigen 85B in Microparticle Vaccine Systems for Protection Against Tuberculosis

Expression of recombinant Mycobacterium bovis antigen 85B by Mycobacterium smegmatis mc2

Background Bovine tuberculosis (TB) is a disease which constitutes an important economic and zoonotic problem in Latin America. The etiological agent, Mycobacterium bovis, has several antigens described and well characterized. The M. bovis antigen 85B (Ag85B), encoded by fbpB gene, is the bacillus immunodominant antigen and promising target for vaccine and diagnosis development [1]. Ag85B combi...
