Organophosphate insecticides target the serotonergic system in developing rat brain regions: disparate effects of diazinon and parathion at doses spanning the threshold for cholinesterase inhibition.

abstract：:The spatial and temporal regulation of intracellular free Ca2+ serves as a modulator of signal transduction pathways involved in cell growth and differentiation. Thus, interference of metals with intracellular Ca2+ homeostasis has been considered as a target of toxic action. We used the fluorescence indicator fura-2 t...
