Background

Nigericin is an antibiotic derived from S. hygroscopicus that acts as a potassium ionophore promoting K⁺/H⁺ exchange across mitochondrial membranes. Nigericin can be used as a research tool to disrupt intracellular H⁺ and K⁺ concentration, thus altering pH, membrane potential, and cell volume.^1,2,3 At 10 μM, nigericin induces egress of T. gondii parasites by inducing efflux of K⁺.⁴

Nigericin是一种来源于吸湿链霉菌的抗生素，作为K+/H+离子载体，促进线粒体膜上K+/H+[1]的交换。Nigericin可以是一种NLRP3激活剂，以NALP3依赖的方式诱导IL-1β的释放[2]。Nigericin引发丹毒，这种作用与ROS的形成平行，部分原因是氧化应激的诱导。Nigericin触发细胞凋亡[3]。
