oxygen and reactive oxygen species metabolism

The chemical reactions involving dioxygen (O2), or any of the reactive oxygen species, e.g. superoxide anions (O2-), hydrogen peroxide (H2O2), and hydroxyl radicals (-OH).

The chemical reactions involving superoxide, the superoxide anion O2- (superoxide free radical), or any compound containing this species.

The switching of activated B cells from IgM biosynthesis to biosynthesis of an IgA isotype, accomplished through a recombination process involving an intrachromosomal deletion between switch regions that reside 5' of the IgM and one of the IgA constant region gene segments in the immunoglobulin heavy chain locus.

The switching of activated B cells from IgM biosynthesis to biosynthesis of an IgG isotype, accomplished through a recombination process involving an intrachromosomal deletion between switch regions that reside 5' of the IgM and one of the IgG constant region gene segments in the immunoglobulin heavy chain locus.

regulation of isotype switching to IgE isotypes

Any process that modulates the frequency, rate or extent of isotype switching to IgE isotypes.

The chemical reactions involving a xenobiotic compound, a compound foreign to living organisms. Used of chemical compounds, e.g. a xenobiotic chemical, such as a pesticide.

positive regulation of isotype switching to IgE isotypes

Any process that activates or increases the rate, frequency or extent of isotype switching to IgE isotypes.

The chemical reactions involving various organic and inorganic nitrogenous compounds; includes nitrogen fixation, nitrification, denitrification, assimilatory/dissimilatory nitrate reduction and the interconversion of nitrogenous organic matter and ammonium.

regulation of isotype switching to IgA isotypes

Any process that modulates the frequency, rate or extent of isotype switching to IgA isotypes.

Any process that modulates the frequency, rate or extent of nitrogen utilization.

The formation from simpler components of nitric oxide, nitrogen monoxide (NO), a colorless gas only slightly soluble in water.
