Expression and serological diagnosis of Mycobacterium tuberculosis CFP-10 and Rv2626c proteins

Expression and serological diagnosis of Mycobacterium tuberculosis CFP-10 and Rv2626c proteins.

We constructed a Mycobacterium tuberculosis vector expressing CFP-10 and Rv2626c to examine the expression of these proteins in Escherichia coli as well as their immunoreactivity. The CFP-10 and Rv2626c genes were amplified from tuberculosis H37Rv genomic DNA using polymerase chain reaction. They were ligated into the expression vector PET30a and expressed in E. coli. Histidine tag nickel colum...

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...

expression 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

cloning, expression and purification of mycobacterium tuberculosis esat-6 and cfp-10 antigens.

background and objectives: esat-6 (6-kdaearly secretory antigenic target) and cfp-10 (10-kda culture filtrate protein) have been described as dominant antigens recognized by t-cells and considered as virulence factors in mycobacterium tuberculosis . the aim of this study was to clone, express and purify recombinant esat-6 andcfp-10 proteins of m. tuberculosis in soluble form. materials and meth...

Heterologous Expression, Purification, and Characterization of the HspX, Ppe44, and EsxV Proteins of Mycobacterium tuberculosis

Background: Subunit vaccines are appropriate vaccine candidates for the prevention of some infections. In this study, three immunogenic proteins of Mycobacterium tuberculosis, including HspX, Ppe44, and EsxV as a new construction, were expressed alone and as a fusion protein to develop a new vaccine candidate against tuberculosis infection. Methods: To make the fusion protein, the three genes ...
