Ex vivo activation of peripheral blood mononuclear cells:

…For the activation of monocytes, 200 l PBMC were stimulated in separate wells (ninety-six-well plates) with 10 g/l of ultra-pure lipopolysaccharide (LPS; List Biological Laboratories, Inc.) or an equal volume of sterile endotoxin-free water as a negative control. PBMC were incubated at 37C in 5 % CO₂ and supernatants were removed after 24, 48 and 72 h for the analysis of monocyte cytokine production as described below.

Immuno-assays:

…Plates were frozen at -80C until the day of use when they were thawed to 37C. 380 l of fresh whole blood anticoagulated with citrate from each subject was mixed 1:1 with RPMI media and added to each well [23]. Final concentrations of stimuli were: …E. coli O111:B4 LPS 10 ng/ml (List Biologicals), and S. minnesota Re595 LPS 10 ng/ml (List Biologicals). Plates were placed on a shaker at 37C under 5% CO₂ for 6 hours before begun spun down and the plasma supernatant removed and frozen at -80C. …

Coupling of FFA3 to N-type Ca²⁺ channels in sympathetic neurons:

Expression of FFA3 followed by C2 or C3 application produced I_Ca inhibition typical of G_i/o-coupled GPCRs, which was rapid in both onset and washout, voltage-dependent, and greatly reduced by PTX pretreatment…

In experiment 3, a lateral incision of the neck skin was performed. Then, in seven rats the SLN of the left vagus nerve proximal to the point passing through the thyrohyoid membrane was dissected free from surrounding tissues, and cut. In nine other rats, the left GpN-ct distal to the branching point of the carotid sinus nerve was dissected free from surrounding tissues, and cut. The central cut end of these nerves was inserted into a piece of polyethylene cup (inner diameter: 1.01.5 mm) which was filled with 0.2 µl of 1% CTb (List Biological Laboratories, Campbell, CA) dissolved in 0.1 M phosphate buffer; the space between the inserted nerve and the opening of the cap was sealed with vaseline and/or dental wax…
