Bordetella bronchiseptica responses to physiological reactive nitrogen and oxygen stresses.
Bordetella bronchiseptica can establish prolonged airway infection consistent with a highly developed ability to evade mammalian host immune responses. Upon initial interaction with the host upper respiratory tract mucosa, B. bronchiseptica are subjected to antimicrobial reactive nitrogen species (RNS) and reactive oxygen species (ROS), effector molecules of the innate immune system. However, t...
متن کاملBiochemistry of Reactive Oxygen and Nitrogen Species
Reactive species or free radicals include reactive oxygen and nitrogen species that are called reactive oxygen nitrogen species. Reactive oxygen species are formed as a natural by-product of the normal metabolism of oxygen and have significant roles in cell signaling and homeostasis. The reactive oxygen species are generated as a byproduct of biochemical reactions, in mitochondria, peroxisomes,...
متن کاملResponse of Mycobacterium tuberculosis to reactive oxygen and nitrogen intermediates.
BACKGROUND Mycobacterium tuberculosis is a significant human pathogen capable of replicating in mononuclear phagocytic cells. Exposure to reactive oxygen and nitrogen intermediates is likely to represent an important aspect of the life cycle of this organism. The response of M. tuberculosis to these agents may be of significance for its survival in the host. MATERIALS AND METHODS Patterns of ...
متن کاملBioimaging Probes for Reactive Oxygen Species and Reactive Nitrogen Species
Reactive oxygen species (ROS) play key roles in many pathogenic processes, including carcinogenesis, inflammation, ischemia-reperfusion injury and signal transduction. Also, reactive nitrogen species (RNS) cause various biological events such as neurodegenerative disorders. Sensitive and specific detection methods for ROS and RNS in biological samples should be useful for elucidation of biologi...
متن کاملScavenging and antioxidant potential of physiological taurine concentrations against different reactive oxygen/nitrogen species.
While several studies have been conducted on the antioxidant properties of the beta-amino acid taurine, these studies all used concentrations lower than what is found physiologically. This study investigates the scavenging and antioxidant properties of physiological taurine concentrations against different reactive species. No reactivity between taurine and hydrogen peroxide was found; however,...
