Title M Current-Based Therapies for Nerve Agent Seizures.
Publication Date Jul 2013

Abstract This is a proposal to develop novel, mechanism-based therapies for the treatment of organophosphate (OP) nerve agent-induced seizures. The primary goal of this proposal is to test two interrelated hypotheses: (1) Cholinergic nerve agents cause neuronal hyper-excitability by inhibiting M/KCNQ2/3 potassium channels. (2) Cholinergic seizures can be blocked by drugs that can open potassium channels mediating M currents. These hypotheses will be tested by accomplishing three aims. (Aim 1) To test whether modulation of M channel modulators (antagonists and openers) glutamatergic transmission on CA1 pyramidal neurons and dentate granule cells; (Aim 2) To characterize the effects of M current enhancers on excitabtility and bursting of CA1 pyramidal neurons; (Aim 3) To test anticonvulsant action of three M-Channel openers in cholinergic overstimulation-induced status epilepticus.
