Abstract：
:Effective treatments to improve survivability following exposure to the nerve agent soman have been established and are currently available. Unfortunately, electrographic brain seizures, neuroinflammation and brain cell death are still a potential problem even with treatment. In the present study we have characterized the time course of the central neuro-inflammatory gene response using quantitative real time-PCR (TaqMan). Male Sprague-Dawley rats were pre-treated with HI-6 (1-2-hydroxy-iminomethyl-1-pyridino-3-(4-carbamoyl-1-pyridino-2-oxapropane dichloride); 125 mg/kg, i.p.) and exposed 30 min later to 1.6 x LD(50) of soman (pinacolyl methyl-phosphonofluoridate, 180 microg/kg, s.c.) followed at 1 min by atropine methyl nitrate (4 mg/kg, i.m.). Initially, a significant and dramatic upregulation of tumor necrosis factor-alpha and vascular cell adhesion molecule-1 mRNA levels was measured 2 h post-exposure followed at 6 h by upregulation of interleukin-1beta, interleukin-6, E-selectin, and intercellular adhesion molecule-1 with eventual resolution by 24-48 h. In conclusion, an acute and transient upregulation of the inflammatory gene response is activated following soman exposure that may be involved in the soman-induced brain injury process.
