WebThe term ionophore (from Greek ion carrier or ion bearer) was proposed by Berton Pressman in 1967 when he and his colleagues were investigating the antibiotic mechanisms of valinomycin and nigericin. [4] Many ionophores are produced naturally by a variety of microbes, fungi and plants, and act as a defense against competing or pathogenic species. WebIn summary care must be taken when using the putative K+/H+ ionophore nigericin as an experimental tool in synaptosomes, as under standard conditions (i.e. in the presence of high external Na+) nigericin behaves as a Na+/H+ ionophore.

WebNigericin acts as a potassium ionophore. It probably activates NLRP3 through its ionophore function which allows the intracellular K+ efflux across the membrane3. Whether the formation of non-selective pannexin-1 pores also contributes to NLRP3 activation upon Nigericin treatment remains unclear4. 1. Mariathasan S. et al., 2006. WebIonophore antibiotics are fermentation products of different Streptomyces species and other fungi. They are polyether antibiotics, which exert their antibiotic action by disrupting the transport of ions in the cell membranes.
