Retrograde tracer experiments:

Injections of the retrograde tracer cholera toxin B subunit (CTB from List Biological Laboratories, Campbell, CA) were targeted to the medial preoptic area (n = 6) and the arcuate nucleus (n=6), unilaterally…Glass micropipettes of 15-20µm internal diameter were filled with 0.25% CTB dissolved in 0.1 M phosphate buffer at pH 7.4 (PB) and lowered to the following stereotaxic coordinates…Once the pipette was in place, the CTB was injected by iontophoresis using a constant current source…

Lipopolysaccharide challenge:

Mice were intravenously injected at 0900h with 50 g/kg lipopolysaccharide (LPS) from Salmonella minnesota R595 (List Biological Laboratories Inc, Hornby, Canada) into the tail vein. Blood samples were collected after 30, 60, 90, and 120 minutes for cytokine analysis.

Experimental autoimmune encephalomyelitis (EAE) induction:

EAE was induced in 812 week old male and female mice by subcutaneous injection into the flanks and base of tail of 125g of MOG_35-55 (MEVGWYRSPFSRVVHLYRNGK) or PLP_139-151 (HSLGKWLGHPDKF) (Auspep, Australia) emulsified in Complete Freunds Adjuvant containing 4mg/ml Mycobacterium tuberculosis H37Ra (Difco, Detroit, MI). Mice also received an intraperitoneal (i.p) injection of 400ng pertussis toxin (List Biological, Campbell, CA) on days 0 and 3 of induction. Assessments of EAE severity were performed daily according to a 9-point paraplegia scale with 0.5-point increments …

2.2.2 Immunization of mice
 
Mice were immunized by a subcutaneous injection of 100µl of the prepared emulsion in
the ventral thorax, with an injection of 50µl in two sides in the chest (left and right side).
At the time of immunization and 2 days after, mice were injected intraperitoneally with
75ng/ml pertussis toxin (List Biologicals, Campbell, CA).

EAE:

Pertussis toxin (300 ng; PTX, List Laboratories, Campbell, CA) was injected intravenously on the day of MOG 35 – 55 immunization and two days later. The remaining six sham mice underwent the same immunization procedure with only IFA without MOG 35 – 55 . Mice were assessed daily for neurological disabilities using a standard clinical score [ 33 ] system: …
