This special issue will describe cutting-edge translational research on the development of safe and effective therapeutics for treating exposure to toxic chemical threat agents that target the nervous system. These studies are supported by the National Institutes of Health (NIH) Countermeasures Against Chemical Threats (CounterACT) program. Chemical threats include chemical warfare agents, pesticides and other toxic chemicals whose primary mode of action is targeted within the nervous system. Depending on the dose, the effects of these toxic chemicals can be lethal or cause serious morbidity including neuropathology and neurological deficits. Current topics in research on organophosphorus pesticides and chemical warfare agents include developing alternatives to currently approve acetylcholinesterase reactivators, control of seizures that are refractory to benzodiazepine drugs, and treatments for serious morbidity caused by non-lethal exposures. There is also an effort to understand the mechanisms of toxicity and treatments for other neuro-active agents such as tetramine and hydrogen sulfide. A robust translational research effort on nerve agents is essential for being better prepared with an effective medical response capability during chemical emergencies.
