1. Respiratory burst

   Respiratory burst (or oxidative burst) is the rapid release of the reactive oxygen species (ROS), superoxide anion (O−2) and hydrogen peroxide (H2O2), from different cell types. This is usually utilised for mammalian immunological defence, but also plays a role in cell signalling. Respiratory burst is also implicated in the ovum of animals following fertilization. It may also occur in plant cells.

1. Respiratory burst

   Respiratory burst is the rapid release of reactive oxygen species from different types of cells. Usually it denotes the release of these chemicals from immune cells, e.g., neutrophils and monocytes, as they come into contact with different bacteria or fungi. They are also released from the ovum of higher animals after the ovum has been fertilized. These substances can also be released from plant cells. Respiratory burst plays an important role in the immune system. It is a crucial reaction that occurs in phagocytes to degrade internalized particles and bacteria. NADPH oxidase, an enzyme family in the vasculature, produces superoxide, which spontaneously recombines with other molecules to produce reactive free radicals. The superoxide reacts with NO, resulting in the formation of peroxynitrite, reducing the bioactive NO needed to dilate terminal arterioles, feed arteries and resistance arteries. Superoxide anion, peroxynitrite, and other reactive oxygen species also lead to pathology via peroxidation of proteins and lipids, and via activation of redox sensitive signaling cascades and protein nitrosylation. NADPH oxidase activation has been suggested to depend on prior PKC activation. Myeloperoxidase uses the reactive oxygen species hydrogen peroxide to produce hypochlorous acid. Many vascular stimuli, including all those known to lead to insulin resistance, activate NADPH oxidase via both increased gene expression and complex activation mechanisms.-

1. Respiratory Burst

   A large increase in oxygen uptake by neutrophils and most types of tissue macrophages through activation of an NADPH-cytochrome b-dependent oxidase that reduces oxygen to a superoxide. Individuals with an inherited defect in which the oxidase that reduces oxygen to superoxide is decreased or absent (GRANULOMATOUS DISEASE, CHRONIC) often die as a result of recurrent bacterial infections.
