Perampanel and decanoic acid show synergistic action against AMPA receptors and seizures.

Epilepsia 2018 11 15;59(11):e172-e178. Epub 2018 Oct 15.

Centre for Biomedical Sciences, School of Biological Sciences, Royal Holloway University of London, Egham, UK.

Perampanel is an adjunctive treatment for epilepsy that works through the direct inhibition of AMPA receptors. The same molecular mechanism has recently been shown for a fatty acid, decanoic acid, prescribed in the medium chain triglyceride ketogenic diet for the treatment of patients with drug-resistant epilepsy. Because each compound has been proposed to act through a distinct AMPA receptor binding site, we predicted that perampanel and decanoic acid would act synergistically against AMPA receptors and, consequently, seizures.

Characterization of acute intrastriatal effects of paraoxon on in vivo dopaminergic neurotransmission using microdialysis in freely moving rats.

Toxicol Lett 2018 Dec 4;299:124-128. Epub 2018 Oct 4.

Department of Functional Biology and Health Sciences, Faculty of Biology, University of Vigo, Campus Lagoas Marcosende, 36310 Vigo, Spain.

Paraoxon (POX) is an extremely neurotoxic organophosphorous compound (OP) which main toxic mechanism is the irreversible inhibition of cholinesterase. Although the cholinergic system has always been linked as responsible for its acute effects, experimental studies have suggested that the dopaminergic system also may be a potential target for OPs. Based on this, in this study, the acute intrastriatal effects of POX on dopaminergic neurotransmission were characterized in vivo using brain microdialysis in freely moving rats. Read More

The time course of blood brain barrier leakage and its implications on the progression of methamphetamine-induced seizures.

Neurotoxicology 2018 12 30;69:130-140. Epub 2018 Sep 30.

Division of Neurotoxicology, National Center for Toxicological Research, Jefferson, 72079, AR, USA.

The initial goals of these experiments were to determine: 1) if blood-brain barrier (BBB) breakdown was a cause or an effect of METH-induced seizures; 2) all the brain regions where BBB is disrupted as seizures progress; and 3) the correlations between body temperature and vascular leakage and neurodegeneration. A fourth objective was added after initial experimentation to determine if sub-strain differences existed in adult male C57 B6 J (Jackson laboratories, JAX) versus C57 B6N (Charles River, CR) mice involving their susceptibility to BBB breakdown and seizure severity. With the 1st "maximal" intensity myoclonic-tonic seizure (MCT) varying degrees of IgG infiltration across the BBB (≤1 mm) were prominent in olfactory system (OS) associated regions and in thalamus, hypothalamus and neocortex.
