Retrograde tracing of LPT/MLR neurons after CTb injections in the spinal cord:

Rats (n=4) were injected with 15nl of cholera toxin B subunit (CTb, 1% in saline) in the spinal ventral horn at the C8-T1 level. 2 weeks after the injection the rats were transcardially perfused with saline and 4% phosphate-buffered formalin. Brains were cut at 40m sections and processed immunohistochemically for CTb and choline acetyltransferase (ChAT). In brief, the sections were incubated in primary antibody (polyclonal goat anti-CTb antibody; 1:10,000; List Biologicals) for 24 hours at room temperature followed by incubation in …

Experimental Protocols:

Rats received intravenous (femoral vein) LeTx [lethal factor (LF) and protective antigen (PA); LF 100 g/kg+PA 200 g/kg; infusion rate 1.0 ml/hr) or vehicle (PA+PBS with 1% BSA, 0.5 ml/hr or PBS with 1% BSA, 1.0 ml/hr]. LF and PA were recombinant proteins prepared from B. anthracis and purchased from List Biological Laboratories. Experiments were completed in INT and SAD rats. MAP, HR, lumbar SND, and renal SND were recorded continuously during LeTx or vehicle infusions. The maximum infusion duration was 3 hours; however, due to LeTx-induced reductions in MAP, the majority of experiments were terminated before the completion of 3 hours. The effect of a short bout of combined hypoxia and hypercapnia on SND responsivity, produced by shutting off the mechanical ventilator for a short period of time (1530 s), was determined near the end of LeTx and vehicle infusion experiments. Arterial pO2 and pCO2 levels were measured before and 1530 s after ventilation was terminated. Rats were euthanized by an intravenous overdose of methohexital sodium (150 mg/kg iv).
