Imaging of receptor trafficking by using -bungarotoxin-binding-site-tagged receptors

Imaging of receptor trafficking by using -bungarotoxin-binding-site-tagged receptors

-Amino-3-hydroxy-5-methyl-4-isoxazole-propionate (AMPA) receptors mediate excitatory synaptic transmission and are dynamically regulated during synaptic plasticity in the CNS. The membrane trafficking of AMPA receptors to synapses is critical for the regulation of the efficacy of excitatory synaptic transmission. Direct imaging of AMPA receptors in various cell compartments is important to diss...

Aplysia acetylcholine receptors: blockade by and binding of alpha-bungarotoxin.

Binding of -bungarotoxin to acetylcholine receptors in mammalian muscle.

Experiments were performed to determine the specificity of Il25I]a-bungarotoxin binding to skeletal muscle. In adult rat diaphragm, [1251]a-bungarotoxin was found to bind almost exclusively to those regions of the muscle that contain endplates and are known to be sensitive to acetylcholine. In contrast, chronically denervated adult muscle and muscle from neonatal rats, both of which are sensiti...

Optimum Conditions of Radioligand Receptor Binding Assay of Ligands of Benzodiazepine Receptors

To obtain drugs which are more selective at benzodiazepine (BZD) receptors, design and synthesis of functionally selective ligands for BZD receptors is the current strategy of our pharmaceutical chemistry department. The affinity of newly synthesized ligands is assessed by radioligand receptor binding assays. Based on our previous studies, 2-phenyl-5-oxo-7-methyl-1,3,4-oxadiazolo[a,2,3]-pyrimid...

In silico Study of Toll-Like Receptor 4 Binding Site of FimH from Uropathogenic Escherichia coli

  Introduction : The innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (PAMPs) by Toll-Like Receptors (TLRs). Interaction of bacterial PAMPs by TLRs results in activation of innate and acquired immunity. FimH adhesin, a minor component of type 1 fimbriae encoded by Uropathogenic Escherichia coli (UPEC) is a PAMP of TLR4 tha...
