Inhibition of mitochondrial permeability transition (mPT) has emerged as a promising approach for neuroprotection and development of well-tolerated mPT inhibitors with favorable blood-brain barrier penetration is highly warranted. In a recent study, 28 clinically available drugs with a common heterocyclic structure were identified as mPT inhibitors e.g.(More)
We examined the protective effects of the immunosuppressants cyclosporin A (CsA) and FK506 on abnormal cytosolic Ca²⁺ ([Ca²⁺]c) and mitochondrial Ca²⁺ concentration ([Ca²⁺]m) dynamics induced by ischemia or high L-glutamate concentration in mouse brain slice preparations. We used fura-4F and rhod-2 as indicators for [Ca²⁺]c and [Ca²⁺]m, respectively, in(More)
We developed a conventional imaging method to measure Ca(2+) concentration in cytosol (using FuraRed as an indicator) and mitochondria (using Rhod-2 as an indicator), simultaneously, by alternative excitation with specific wave length. After confirming the availability of the method in Hela cells, we applied it to mouse whole-brain slice -preparation, which(More)
