Antagonism of rat excitatory amino acid receptors by a synthetic analog [philanthotoxin-343 (PhTX-343)] of a polyamine amide, wasp toxin (philanthotoxin-433) and a structurally related spider toxin, argiotoxin-636 (ArgTX-636), was examined in Xenopus oocytes injected with rat brain RNA or RNA

1. The blocking action of delta-philanthotoxin (PhTX-4.3.3), a wasp toxin composed of a polyamine chain, an aromatic amino acid (tyrosyl) nucleus and an aliphatic (butanoic) acid was studied, together with 33 structural analogues, at the glutamatergic neuromuscular synapse in larvae
H Karst et al.
European journal of pharmacology, 270(4), 357-360 (1994-08-03)
The wasp venom philanthotoxin-4.3.3 (PhTX-4.3.3) is an antagonist of glutamate transmission in the insect as well as in the mammalian brain. It was recently shown that PhTX-4.3.3 inhibits the N-methyl-D-aspartate (NMDA) transmission in rat hippocampus. In this study we show

Neurotransmitter release is stabilized by homeostatic plasticity. Presynaptic homeostatic potentiation (PHP) operates on timescales ranging from minute- to life-long adaptations and likely involves reorganization of presynaptic active zones (AZs). At Drosophila melanogaster neuromuscular junctions, earlier work ascribed AZ enlargement by

Nature communications, 10(1), 4089-4089 (2019-09-11)
The α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid subtype glutamate receptors (AMPARs) mediate the fast excitatory synaptic transmission in the mammalian brain and are important for synaptic plasticity. In particular, the rapid insertion of the GluA1 homomeric (GluA1-homo) AMPARs into the postsynaptic membrane is considered
