Animal maintenance and neuron ablation

… All except Tph2^lox/lox mice were on the C57Bl/6 background (> 9 generations backcrossed); Tph2^lox/lox mice were on a mixed 129/Sv x C57Bl/6 background. Agrp^DTR/DTR male mice were bred with Slc17a6^lox/lox female mice to generate Agrp^DTR/+; Slc17a6^lox/+ mice, which were further bred to each other to create Agrp^DTR/+; Slc17a6^lox/lox mice and Agrp^DTR/+; Slc17a6^lox/+ control mice. Similar breeding strategy was adopted when generating Agrp^DTR/+; Tph2^lox/lox mice and Agrp^DTR/+; Grin1^lox/lox mice. Mice were group housed with standard chow diet (LabDiet 5053) and water provided ad libitum until the beginning of the experiments. All experiments were performed with ~8-wk-old male mice. To ablate AgRP neurons, mice carrying the Agrp^DTR allele, were injected twice with DT (50 g/kg; intramuscular; 2 d apart; List Biological Laboratories, Campbell, CA)⁴. The extent of ablation (>95%) was determined by immunohistochemistry⁴⁷.

Sample Preparation:

To provide a source of data that was rich in content for functional annotation, we prepared a complex sample of soluble proteins from neutrophils activated by lipopolysaccharide (LPS). The human promyelocytic HL-60 cell line (ATCC) was differentiated in culture using 1 M alltrans retinoic acid (Sigma-Aldrich), 6 pM 1,25-Dihydroxyvitamin D3 (Sigma-Aldrich), and 30 ng/mL granulocyte-colony stimulatory factor (Invitrogen) in Iscove’s Modified Dulbecco’s medium (Mediatech, Inc.) supplemented with 20% FBS and 4 mM L-glutamine.³¹ Cells were activated via treatment with 100 ng/mL of lipopolysaccharide (LPS) from E. coli O111:B4 (List Biological Laboratories) for 30 minutes. …

EAE induction, disability evaluation and tissue harvesting:

… For the mouse model, 8-10 weeks-old female C57BL/6 mice (Taconic, Hudson, NY) were immunized subcutaneously in the flank with 200 µg myelin oligodendrocyte glycoprotein peptide 3555 (MEVGWYRSPFSRVVHLYRNGK; Stanford PAN Facility, Stanford, CA) emulsified in CFA that had been supplemented with M. tuberculosis strain H37RA (MT; Difco Laboratories, Detroit, MI) at 7 mg/ml. All mice also received an intraperitoneal injection of 350 ng pertussis toxin (List Biological, Campbell, CA) at 0 and 48 h post-immunization. …

Experimental protocols:

After completion of the surgical procedures, anesthetized rats were allowed to stabilize for 60 min before initiation of experimental protocols. As described by Cui et al. (4, 6), rats received LeTx [LF (100 g/kg) + PA (200 g/kg) infused at 0.5 ml/h] or vehicle (PA + PBS with 1% BSA or PBS with 1% BSA infused at 0.5 ml/h). LF and PA are recombinant proteins prepared from B. anthracis and purchased from List Biological Laboratories. Experiments were completed in intact and SAD rats. LeTx or vehicle was infused intravenously via a femoral venous catheter, and the dose of LeTx was chosen on the basis of the time course of physiological responses to intravenous LeTx infusions as reported by Cui and colleagues (6). MAP, HR, and SND were recorded continuously during intravenous LeTx or vehicle infusions. The maximum infusion duration was 6 h; however, because of LeTx-induced reductions in arterial blood pressure, the majority of experiments were terminated before 6 h. Additional experiments involved the intravenous infusion of sodium nitroprusside (SNP) at a dose (20 g/kg) that reduced basal levels of MAP to 5060 mmHg. At the end of experiments, rats were euthanized by an overdose of methohexital sodium (150 mg/kg iv).
