Immunologic similarities between the hypothalamic alpha-bungarotoxin receptor and the Torpedo californica nicotinic
Brain Research
|December 14, 1979
Abstract:
The solubilized rat central nervous system (hypothalamic) nicotinic cholinergic receptor and the Torpedo nicotinic cholinergic receptors are immunologically similar and show greater than 60% immunologic cross-reactivity using a double-antibody technique. Antibodies to the Electrophorus and Torpedo receptors also decrease the rate of alpha-bungarotoxin binding to these membraneous receptors. It is concluded that the Torpedo and hypothalamic nicotinic receptors are immunologically similar and that receptor binding sites for alpha-bungarotoxin and antibodies are physically close. These studies indicate that alpha-bungarotoxin can be used to study the nicotinic cholinergic receptor of the rat hypothalamus.
