Recently a novel genetically modified mouse strain with serum carboxylesterase knocked-out and the human acetylcholinesterase gene knocked-in (KIKO) was created to simulate human responses to nerve agent (NA) exposure and its standard medical treatment. A adenosine receptor (AAR) agonist N-bicyclo-(2.2.

Article Synopsis
  • - Soman causes harmful excitotoxic effects by blocking acetylcholinesterase, leading to prolonged seizures (SSE) and brain damage in models.
  • - A study tested the delayed use of the adenosine receptor agonist ENBA alongside current treatments (atropine, 2-PAM, midazolam) in rats, finding that ENBA improved seizure termination and reduced brain damage compared to midazolam alone.
  • - Despite the benefits in seizure control and neuroprotection, the combination of ENBA with midazolam resulted in lower survival rates after 14 days, suggesting that ENBA may enhance midazolam's harmful effects on neurons, requiring careful dosage adjustments.

Exposure to organophosphorus compounds, such as soman (GD), cause widespread toxic effects, sustained status epilepticus, neuropathology, and death. The A adenosine receptor agonist N-bicyclo-(2.2.

Organophosphorus nerve agents, such as soman (GD), produce excitotoxic effects resulting in sustained status epilepticus (SSE) and brain damage. Previous work shows that neuronal inhibitory effects of A adenosine receptor (AAR) agonists, such as N- Bicyclo (2.2.

Animal models are essential for evaluating the toxicity of chemical warfare nerve agents (CWNAs) to extrapolate to human risk and are necessary to evaluate the efficacy of medical countermeasures. The Göttingen minipig is increasingly used for toxicological studies because it has anatomical and physiological characteristics that are similar to those of humans. Our objective was to determine whether the minipig would be a useful large animal model to evaluate the toxic effects of soman (GD).
