Web17 nov. 2024 · However, we found that ionophore nigericin can disturb plasma membrane potential, intracellular pH, mitochondrial membrane potential and autophagy at once. By affecting all of the tested homeostasis-maintaining systems, nigericin induced senolytic action towards stromal and epithelial senescent cells of different origins. WebNigericin sodium salt is a potassium ionophore, exchanges K + for H + across biological membranes, in a similar manner to Valinomycin (Cat. No. 3373). Stimulates mitochondral ATPase activity and disrupts membrane potential. Also acts as an ionophore for Pb 2+ with no activity with other divalent cations.
