[ 1 ] - Construction, expression, purification and characterization of secretin domain of PilQ and triple PilA-related disulfide loop peptides fusion protein from Pseudomonas aeruginosa
Objective(s): Infection with Pseudomonas aeruginosa has been a long-standing obstacle for clinical therapy due to the complexity of the genetics and pathogenesis, as well for widespread resistance to antibiotics, thus attaching great importance to explore effective vaccines for prevention and treatment. This paper focuses on the introduction of novel Pseudomonas aeruginosa type IV pili (T4P)-ba...
[ 2 ] - Differential protein expression in Mycobacterium tuberculosis susceptible and multidrug resistant isolates
Introduction: Infections by multidrug resistant Mycobacterium tuberculosis (MDR-TB) is a major public health challenge. Secretion of proteins by M. tuberculosis plays an important role in the pathogenesis of the bacterium. We compared the protein profiles of susceptible M. tuberculosis and MDR-TB isolates using proteomic analyses, namely two dimensional gel electrophoresis (2DE) and mass spectr...
[ 3 ] - Protein profiling and analysis of drug sensitive and multidrug resistant isolates of Mycobacterium tuberculosis by native polyacrylamide gel electrophoresis and mass spectrometry
Introduction: Tuberculosis (TB) remains a deadly infectious disease despite all the efforts to reduce its incidence. Spread of multidrug resistant TB has seriously undermined the efforts to control the disease globally. In this study protein expression profile of MDR and sensitive isolates of MTB were analyzed and compared in order to identify proteins, which could be used in prevention, diagno...
[ 4 ] - Development of a Novel Anti-Adhesive Vaccine Against Pseudomonas aeruginosa Targeting the C-terminal Disulfide Loop of the Pilin Protein
The type IV pili (T4P) is a major virulence factor of Pseudomonas aeruginosa (P. aeruginosa) that is associated with primary adhesion, biofilm formation and twitching motility. This study focuses on the introduction of a novel biologically active subunit vaccine derived from the disulfide loop (DSL) of P. aeruginosa pilin. We investigated the expression of the novel PilA in-frame with pET26a ve...
[ 5 ] - High Yield Overexpression, Refolding, Purification and Characterization of Pseudomonas aeruginosa Type B-Flagellin: An Improved Method Without Sonication
Pseudomonas aeruginosa as an opportunistic pathogen is a significant cause of acute and chronic infections in patients with compromised defenses. This bacterium is motile via a single polar flagellum made of polymerized flagellin subunits differentiated into two major serotypes: A and B. flagellin plays an important role as a virulence factor in the adhesion, colonization and invasion of P. aer...
