Acid-sensing ion channel 1a contributes to the effect of extracellular acidosis on NLRP1 inflammasome activation in cortical neurons.

Yu-Chan Wang et al.

Journal of neuroinflammation, 12, 246-246 (2015-12-31)

Acid-sensing ion channels (ASICs) are cation channels which were activated by extracellular acidosis and involved in various physiological and pathological processes in the nervous system. Inflammasome is a key component of the innate immune response in host against harmful and

Mitochondrial K+ as modulator of Ca(2+)-dependent cytotoxicity in hepatocytes. Novel application of the K(+)-sensitive dye PBFI (K(+)-binding benzofuran isophthalate) to assess free mitochondrial K+ concentrations.

J P Zoeteweij et al.

The Biochemical journal, 299 ( Pt 2), 539-543 (1994-04-15)

In isolated rat hepatocytes a sustained high increase in intracellular free Ca2+ ([Ca2+]i), induced by extracellular ATP, is associated with mitochondrial dysfunction and cell death. The Ca(2+)-induced effects are Pi-dependent and less severe when the intracellular K+ content is low.
