cloning, expression and purification of the factor h binding protein and its interaction with factor h
background and objective: neisseria meningitidis is a leading cause of meningitis and sepsis worldwide. the factor h binding protein (fhbp) is a key virulence factor of neisseria meningitidis that is able to selectively bind to human factor h, the key regulator of the alternative complement pathway, which it has important implications for meningococcal pathogene- sis and vaccine design. the aim...
متن کاملAtypical hemolytic uremic syndrome-associated variants and autoantibodies impair binding of factor h and factor h-related protein 1 to pentraxin 3.
Atypical hemolytic uremic syndrome (aHUS) is a renal disease associated with complement alternative pathway dysregulation and is characterized by endothelial injury. Pentraxin 3 (PTX3) is a soluble pattern recognition molecule expressed by endothelial cells and upregulated under inflammatory conditions. PTX3 activates complement, but it also binds the complement inhibitor factor H. In this stud...
متن کاملBioinformatics prediction and experimental validation of VH antibody fragment interacting with Neisseria meningitidis factor H binding protein
Objective(s): We previously conducted an in silico research on the interactions between the ribosome display-selected single chain variable fragment (scFv) and factor H binding protein (fHbp) of Neisseria meningitidis. We found that heavy chain variable (VH) fragment of this scFv had considerable affinity to fHbp. These results led us to evaluate the ability of this sm...
متن کاملComplement factor H binds at two independent sites to C-reactive protein in acute phase concentrations.
Factor H (FH) regulates the activation of C3b in the alternative complement pathway, both in serum and at host cell surfaces. It is composed of 20 short complement regulator (SCR) domains. The Y402H polymorphism in FH is a risk factor for age-related macular degeneration. C-reactive protein (CRP) is an acute phase protein that binds Ca(2+). We established the FH-CRP interaction using improved a...
متن کاملGlycerol-3-phosphate dehydrogenase 2 is a novel factor H-, factor H-like protein 1-, and plasminogen-binding surface protein of Candida albicans.
Candida albicans uses human complement regulators such as factor H and factor H-like protein 1 (FHL-1) for immune evasion. To define the whole panel of fungal complement-evasion molecules, C. albicans cell extract was absorbed to a factor H-coupled matrix. One 52-kDa protein was eluted and identified by mass spectrometry as glycerol-3-phosphate dehydrogenase 2 (Gpd2). Consequently, Gpd2 was rec...
