Transmitter release was elicited in two ways from cultured cells filled with acetylcholine: (a) in a biochemical assay by successive addition of a calcium ionophore and calcium and (b) electrophysiologically, by electrical stimulation of individual c

A bioluminescent GABA assay is described. The principle of the procedure is based on the action of GABASE (GABA-aminotransferase plus succinic semialdehyde dehydrogenase), coupled to the detection of succinic semialdehyde and NADH, using Photobacteri

By loading cells in culture with acetylcholine (ACh) we have characterized a calcium-dependent release mechanism and shown that it was expressed independently of synthesis or storage of ACh. (Israel et al., 1994, Neurochemistry International 37, 1475

Neuronal properties such as neurotransmitter uptake and release can be expressed in non-neuronal cells. We show here that fibroblasts—mouse cell line L-M(TK − )—are able to take up acetylcholine from the external medium and to release it in res

Treatment with 100 or 250 microM ZnCl2 irreversibly blocked neurotransmission in the Torpedo electric organ by inhibiting acetylcholine (ACh) release. In Zn2+-treated tissue, release failure did not result from impairment of Ca2+ entry since stimulat

Several neuronal and non-neuronal cell lines express a Ca(2+)-dependent mechanism of transmitter release that can be demonstrated after loading the cells with acetylcholine during culture. In contrast, a particular cell line, the neuroblastoma N18TG-

Mediatophore is a protein of approximately 200 kDa able to translocate acetylcholine in response to calcium. It was purified from the presynaptic plasma membranes of the electric organ nerve terminals. Mediatophore is a homooligomer of a 16-kDa subun
