Staphylococcal Bap Proteins Build Amyloid Scaffold Biofilm Matrices in Response to Environmental Signals
Biofilms are communities of bacteria that grow encased in an extracellular matrix that often contains proteins. The spatial organization and the molecular interactions between matrix scaffold proteins remain in most cases largely unknown. Here, we report that Bap protein of Staphylococcus aureus self-assembles into functional amyloid aggregates to build the biofilm matrix in response to environ...
متن کاملTo build a biofilm.
Development is not restricted to so-called higher organisms. Developmental processes in bacteria include differentiation of a single cell, such as the swarmer-to-stalk transition by Caulobacter crescentus and spore formation by Bacillus subtilis. Other microbes, such as Myxococcus xanthus, produce specialized cells within a population to form sporulating fruiting bodies (19). As we learn more a...
متن کاملAntibody Response to Human Extracellular HER2 Subdomain Proteins in Mice
Background: In addition to passive immunotherapy using anti-HER2 monoclonal antibodies, active immunotherapy via HER2 targeting is an interesting approach to inducing specific anti-tumor immune responses. We have recently reported the immunogenicity of HER2 subdomains following DNA immunization and HER2 protein boosting. In the present study, we evaluated the immunogenicity of different HER2 ex...
متن کاملTo BaP or not to BaP? That is the question.
[a]pyrene (BaP), a polycyclic aromatic hydrocarbon (PAH) and animal carcinogen, is used by regulators as the basis for quantitative risk estimation of PAH-containing combustion by-products (1). Is BaP an appropriate predictor of cancer risk for products of incomplete combustion? A multidose, 2-year (chronic) feeding protocol developed by the National Institute of Environmental Health Sciences i...
متن کاملStaphylococcal response to oxidative stress
Staphylococci are a versatile genus of bacteria that are capable of causing acute and chronic infections in diverse host species. The success of staphylococci as pathogens is due in part to their ability to mitigate endogenous and exogenous oxidative and nitrosative stress. Endogenous oxidative stress is a consequence of life in an aerobic environment; whereas, exogenous oxidative and nitrosati...
