… For active EAE induction, 200 ng pertussis toxin (List Biologicals, St. Louis, MO) was administered ip on days 0 and 2 to initiate disease. Animals were similarly immunized for passive EAE; 10 d later, the inguinal, brachial, and axillary LN were removed. …

Experimental Protocols:

Mice were treated with an intraperitoneal injection of 1 mg/kg purified LPS from E. coli 0111:B4 (List Biologicals) 4 hr prior to intravital microscopy. The dose of LPS used in this study was sufficiently low that animals survived anesthesia and hepatic perfusion was not severely diminished. The purity of the commercial LPS was confirmed by inoculation into TLR4 knockout (TLR4^/) animals and observation of no measurable response in any of the parameters reported in this study (data not shown). For platelet depletion experiments, mice were injected i.p. with 50 l anti-mouse thrombocyte serum or 50 l control serum (adsorbed normal rabbit serum) 24 hr prior to LPS administration or E. coli infection. For neutrophil depletion experiments, mice were injected i.p. with 200 g anti-Gr-1 antibody or 200 g rat IgG control antibody 24 hr prior to LPS administration. Platelet and neutrophil depletion were confirmed with SD-IVM (see Figure 2). In some experiments, mice were treated with 2000 U DNase intravenously at various time points after infection with E. coli (noted in the figure legends).

Mouse Treatments and Immunizations:

For immunization with OVA in complete Freunds adjuvant (OVA/CFA), OVA was emulsified in CFA at final concentration of 1 mg/ml OVA, and mice received hind footpad injection of 20 l of OVA/CFA as described (Webster et al., 2006).

Foxp3-DTR mice express simian diphtheria toxin (DT) receptor that allows for depletion of Foxp3⁺ regulatory T cells upon DT administration (Kim et al., 2007; Chinen et al., 2010). For regulatory T cell depletion, wild-type control or Foxp3-DTR mice were injected intraperitoneally with 1.5 g of DT … List Biological Laboratory, Campbell, CA, USA) on days 0, 1, 4, and 7 and examined on day 8. CD4⁺, CD25⁺, Foxp3⁺ regulatory T cells in lymph nodes were depleted by at least 12-fold by day 8.

Muscle afferent tracing:

Three days after PTx injury, animals were reanesthetized and muscle afferents of the deep radial nerve were labeled with 10 µl injections of a 1% solution of cholera toxin B (CTB) (List Biological Laboratories) into the extensor carpi radialis of both forelimbs. The solution was injected over 1 min, and the needle was withdrawn over an additional 1 min. The wound was closed by suturing the overlying muscle and skin. Preliminary data demonstrated that CTB transganglionically labeled both primary sensory afferents and retrogradely labeled motoneuron pools. Anterograde labeling is punctate. Whereas at high magnification we could see punctate ventral horn labeling in proximity to labeled motoneurons, we were not able to distinguish this labeling from other ventral horn label, including portions of motoneuron dendrites and labeled recurrent motoneuron axon collaterals. For this reason, we limited our quantitative CTB analysis to the dorsal horn and intermediate zone. To assay putative 1A boutons on motoneuron cell bodies and proximal dendrites, we examined VgluT1 presynaptic labeling. …

Mucosal Sensitization:

… Briefly, mice were administered 50 mg of OVA (Sigma-Aldrich, St Louis, MO) with 10 µg of CT (List Biologicals, Campbell, CA) in a final volume of 200 µl by using a mouse feeding needle 4 times a week for 4 weeks.

Injection of tracers:

For the immunohistochemistry experiments requiring retrograde tracing, six animals were anesthetized using 5% isoflurane with oxygen and placed in a stereotaxic apparatus (David Kopf Instruments, Tujunga, CA) and stabilized with non-perforating ear bars. … Two l of 1.0% solution of CTb (List, Campbell, CA) was slowly injected into the parabrachial nucleus over a period of 20 minutes, followed by a waiting period of 10 minute before the micropipette was retracted from its position to minimize leakage of the tracer. CTb was injected seven days prior to sacrificing the animals.

Confocal microscopy:

… The sections were incubated in 3 different cocktails: #1) rabbit anti-CGRP at a 1:200 dilution (Sigma, St Louis, MO) and lectin IB4 conjugated to AlexaFluor 568 at a 1:200 dilution (Molecular Probes); #2) rabbit anti-CGRP and guinea pig anti-P2X3 at a 1:25,000 dilution (Neuromics, Edina, MN); #3) goat anti-CTb at a 1:5000 dilution (List Biological), …
