Cholera toxin subunit b immunostaining:

Coronal sections (50 m) of gelatin-embedded cerebella and brainstems were cut on a Peltier freezing microtome and collected in 0.01 m PB. CTb immunostaining was carried out using a standard immunostaining protocol. Free-floating sections were processed for anti-CTb immunostaining using a primary polyclonal goat anti-CTb antibody (List Biological Laboratories, Campbell, CA, USA; 1:15,000) and a …

Cannabinoid and Inflammatory Agonist Treatments:

ECs were grown to confluence before agonist treatment. Unless otherwise noted, in all experiments cells were preincubated with the cannabinoids or the TRPV1 agonist, capsaicin, at the indicated concentrations for 1 h prior to and continuously during the inflammatory agonist treatment. In Fig. 6B, samples were incubated continuously with polymyxin B (Invivogen, San Diego) at 50 g/ml to minimize effects from contaminating LPS. …The inflammatory agonists used include …LPS (List Laboratories, Los Gatos, CA), and…

Electric Cell-Substrate Impedance Sensing (ECIS):

… Inflammatory agonists (FSL, LPS, and TNF) and either NADA (2 or 10 m) or WIN55,212-2 (1 or 2 m) were then added to the wells. Resistance was measured repeatedly in each well for 8 h. …

CT ELISA and -Galactosidase Assays:

CT production was measured using V. cholerae culture supernatants by an GM₁-enzyme-linked immunosorbent assay (GM₁-ELISA) as described previously (4). Purified CT subunit B (List Biological Laboratories, Inc., Campbell, CA) was used to provide a standard curve, and phosphate-buffered saline (PBS) was used as a negative control.

In vitro assay for the effects of DP on macrophages and lymphocytes:

…CCR2 expression on the surface of macrophages after DSP or DP treatment was analyzed by FACS as described previously [19]. Briefly, thioglycolate-recruited peritoneal macrophages were pretreated with 25 M (as dexamethasone) of DSP or DP for 3 hours, and then, were exposed to LPS (O55:B5, 100 ng/mL, List Biological Laboratories, Inc. Campbell, CA) for 18 hours. …
