Talk:Sigma receptor
From Wikipedia, the free encyclopedia
[edit] A receptor doesn't cause effects, its interaction with an ligand does.
"Sigma receptors may induce hallucinogenic effects and also may be responsible for the paradoxical convulsions sometimes seen in opiate overdose."
Not σ-receptors are inducing these effects, their activation by an agonist ligand does; further, in the article, σ-receptors are defined as "non-opioid", yet the image on the right describes it as "sigma opioid receptors".--84.163.87.66 06:56, 28 April 2007 (UTC)
