General description

Nigericin, a polyether ionophore, serves as a probe of ion transport across mitochondrial membranes. It catalyzes the overall electroneutral exchange of K+ for H+(1) and acts as a potassium efflux activator. It may enhance bactericidal action via inflammasome-independent mechanisms specific to NLRP3 (NOD-, LRR- and pyrin domain-containing protein 3). Nigericin is a linear molecule with rings of heterocyclic oxygen together with a hydroxyl group. In the membrane, the molecule cyclizes to form a structure like valinomycin. Nigericin forms a neutral complex while losing a proton when it binds a cation which can diffuse across the membrane as a mobile carrier. Nigericin in protonated noncomplexed form is also considered mobile.

Chemical structure: polyether

Application

Nigericin sodium salt has been used to induce NLRP3 inflammasome activation in human macrophages. It has also been used as a bacterial toxin to trigger IL-1β secretion monocytes.

Biochem/physiol Actions

Polyether ionophore that disrupts membrane potential and stimulates ATPase activity in mitochondria.

Polyether ionophore that disrupts membrane potential and stimulates ATPase activity in mitochondria. Ion selectivity is K⁺> Rb⁺≥ Cs⁺>> Na⁺.

Other Notes

As ion-selective electrode - an efficient K⁺-carrier.

Nigericin decreases intracellular pH (pH(i)) and stimulates prostanoid (PG) synthesis in endothelial cells from cerebral microvessels of newborn pigs. Nigericin-induced PG production was abolished by protein tyrosine kinase (PTK) inhibitors and amplified by phorbol 12-myristate 13-acetate (PMA) or protein tyrosine

Biosensors on the membrane of the vascular endothelium are responsible for sensing mechanical and chemical signals in the blood. Transduction of these stimuli into intracellular signaling cascades regulate cellular processes including ion transport, gene expression, cell proliferation, and/or cell death.
