Okadaic acid, a protein phosphatase inhibitor, stimulates the activity of Na+/H+ and Na+-independent Cl–/HCO3– exchangers in human lymphocytes


The cytosolic pH (pHi) regulatory mechanisms of peripheral blood human lymphocytes and the effect of okadaic acid on the activity of these mechanisms were studied by means of fluorescence imaging microscopy of 2',7'-bis-(carboxyethyl)-5(6')-carboxyfluorescein (BCECF)-loaded individual cells. Lymphocytes recover from a CO2-induced acid load in an… (More)
