The expression of Staphylococcus aureus adhesins in Lactococcus lactis identified clumping factor A (ClfA) and fibronectin-binding protein A (FnBPA) as critical for valve colonization in rats with experimental endocarditis. This study further analyzed their role in disease evolution. Infected animals were followed for 3 d. ClfA-positive lactococci successfully colonized damaged valves, but were...
Leptospirosis is a potentially fatal zoonotic disease in humans and animals caused by pathogenic spirochetes, such as Leptospira interrogans. The mode of transmission is commonly limited to the exposure of mucous membrane or damaged skin to water contaminated by leptospires shed in the urine of carriers, such as rats. Infection occurs during seasonal flooding of impoverished tropical urban habi...
AIMS To characterize the functionality of the Lactobacillus casei BL23 fbpA gene encoding a putative fibronectin-binding protein. METHODS AND RESULTS Adhesion tests showed that L. casei BL23 binds immobilized and soluble fibronectin in a protease-sensitive manner. A mutant with inactivated fbpA showed a decrease in binding to immobilized fibronectin and a strong reduction in the surface hydro...
The ability of Candida albicans to adhere to subendothelial extracellular matrix (ECM) may be important in the pathogenesis of disseminated candidiasis. ECM proteins, such as fibronectin, laminin, and types I and IV collagen bind C. albicans avidly. These proteins all possess heparin-binding domains. The influence of the glycosaminoglycans (GAGS) including heparin, heparan sulfate and dextran s...
A class of proteins that are associated with the cell surface of Gram-positive bacteria has been recognised. Common structural features which are implicated in the proper secretion and attachment of these proteins to the cell surface occur in the C-termini. N-terminal domains interact with the host by binding to soluble host proteins, to matrix proteins or to host cells. They probably have impo...
objective(s) staphylococcus aureus is a leading cause of many nosocomial and community acquired infections. according to many reports, antibiotic therapy can not guarantee the eradication of s. aureus infections. thus designing an adhesin based vaccine could restrain the s. aureus infections. this study designed for construction of a new fusion protein vaccine against s. aureus infections based...
Chinese hamster ovary (CHO) suspension culture cells adhere readily to substrata coated with extracellular matrix proteins such as fibronectin, vitronectin, or laminin. In the case of fibronectin, it is known that adhesion is mediated by an integrin-type, cell surface fibronectin receptor (FnR). We demonstrate here that treatment of CHO cells with submicromolar concentrations of phorbol ester p...
Analysis of parameters governing heparin binding to fibronectin indicates that heparin binding is a necessary, but insufficient, condition for fibronectin cryoprecipitation. Heparin binding to fibronectin is a rapid, readily reversible event which can occur under several conditions which prohibit fibronectin cryoprecipitation. While cryoprecipitation of fibronectin is abolished at temperatures ...
The possibility of using surface topography for guidance of different biological molecules and cells is a relevant topic that can be applied to a wide research activity. This study investigated the adsorption of fibronectin to a diffraction grated silicon surface. The rectangular grating profile featured a controlled surface with 350 nm period and a corrugation depth of 90 nm. Results demonstra...
