abstract：:Exposure of FRTL-5 cells to iodide (I-) in excess of 3 microM suppresses the concentrative uptake of I-. The depression of I- uptake measured at the steady state is due to decrease in the rate of I- influx and not to an effect on I- efflux. Exposure to NaI is associated with decreased T4 secretion and also depressed N...
