Toxicol Sci. 2010 Feb 8.

Beta tubulin from the brains of these mice was diethoxyphosphorylated on tyrosine 281 in peptide GSQQY (281) RALTVPELTQQMFDSK.

Cholinesterase (ChE) and the muscarinic (mAChR) and nicotinic (nAChR) cholinergic receptors were measured in the brains of 86 birds of 20 different species collected in Saskatchewan, Canada during 1991 and 1992.
Acute lethal poisoning by the organophosphate chlorpyrifos did not affect the density of mAChR.

Finally, we exposed zebrafish (Danio rerio) to the serotonin reuptake inhibiting antidepressant sertraline or the organophosphate chlorpyrifos for 21 days.

Acetylcholinesterase (AChE) activity and muscaranic receptor density [i.e., quinuclidinyl benzilate (QNB) binding] were determined in hippocampus and cortex of brains taken from pups 15 hours after the end of behavioral testing (i.e., the morning of PND24, and 27).

There are many secondary targets for OP toxicants as observed for example with the major insecticide chlorpyrifos and its bioactivated metabolite chlorpyrifos oxon (CPO).
Brains from KIAA1363 (-/-) mice show greatly reduced levels of CPO labeling and hydrolytic metabolism compared to brains from wild-type mice.

KIAA1363 was the primary AcMAGE hydrolase in brain, lung, heart and kidney and was highly sensitive to inactivation by chlorpyrifos oxon (CPO) (IC50 2 nM) [the bioactivated metabolite of the major insecticide chlorpyrifos (CPF)].
