The pathways of Li+ transport in neuroblastoma X glioma hybrid cells were studied at 2 mM external Li+. Five components of Li+ transport were identified. (1) A Na+-dependent Li+ countertransport system mediating Li+ transport in both directions across the plasma membrane. This transport pathway is insensitive to ouabain or external K+. It shows(More)
The membrane at the tendinous ends of frog muscle fibres has acetylcholine (ACh) receptors that are blocked by alpha-bungarotoxin. The properties of ACh-activated channels in the myotendinous region were investigated by noise analysis. These channels displayed the same characteristics in normal, denervated and reinnervated muscles. The mean lifetime and(More)
Acetylcholine (ACh)-activated channels in end-plates of frog sartorius muscle were studied at various times after denervation. Mean open times of the synaptic membrane channels were derived from the time constant of decay of miniature end-plate currents (tau MEPC) evoked by ACh quanta released from Schwann cells, which replace the motor nerve terminals(More)
