Several lines of evidence suggest that cyclic GMP might be involved in long-term potentiation (LTP) in the hippocampus. Arachidonic acid, nitric oxide and carbon monoxide, three molecules that have been proposed to act as retrograde messengers in LTP, all activate soluble guanylyl cyclase. We report here that an inhibitor of guanylyl cyclase blocks the(More)
Over expression of Aplysia synaptotagmin in acutely dissected cholinergic neurons from the buccal ganglia, or in primary co-cultures of glutaminergic sensory neurons and motor neurons, causes a reduction synaptic transmission. Anti-sense oligonucleotide treatment of similar cultures produced an enhancement of synaptic transmission. The interaction between(More)
Genes encoding two proteins corresponding to elongation factor G (EF-G) were cloned from Pseudomonas aeruginosa. The proteins encoded by these genes are both members of the EFG I subfamily. The gene encoding one of the forms of EF-G is located in the str operon and the resulting protein is referred to as EF-G1A while the gene encoding the other form of EF-G(More)
