16256208 Slotkin TA, Tate CA, Cousins MM, Seidler FJ: Imbalances emerge in cardiac autonomic cell signaling after neonatal exposure to terbutaline or chlorpyrifos, alone or in combination. Brain Res Dev Brain Res. 2005 Dec 7;160(2):219-30. Epub 2005 Oct 26.

In neonatal rats, we examined the effects of exposure to terbutaline, a beta-adrenoceptor (betaAR) agonist used to arrest preterm labor, and chlorpyrifos (CPF), a widely used organophosphate pesticide that acts in part through inhibition of cholinesterase, using scenarios mimicking the likely developmental stages corresponding to peak human exposures: postnatal days (PN) 2-5 for terbutaline and PN11-14 for CPF.

Toxicol Appl Pharmacol. 2005 Mar 1;203(2):154-66.

We examined the long-term effects of developmental exposure of rats to terbutaline, a beta-adrenoceptor agonist used to arrest preterm labor, and the organophosphorus insecticide chlorpyrifos (CPF) separately and together.

Terbutaline, which is chemically unrelated to CPF and which stimulates neuronal cell metabolism through direct actions on beta-adrenoceptors, also elicited oxidative damage in the developing brain with greater sensitivity in the second postnatal week.

These outcomes and sex selectivity resemble earlier findings at the cellular level, which identified hepatic hyperresponsiveness to gluconeogenic inputs from beta-adrenoceptors or glucagon receptors.

In addition to basal AC activity, we assessed the AC response to direct enzymatic stimulants [forskolin, manganese (Mn (2+))]; the response to isoproterenol, which activates signaling through beta-adrenoceptors (betaARs); and the concentration of betaAR binding sites.
