In vitro cytokine analysis:

Microglia were cultured at 110⁶ cell/ml overnight followed by 18 hrs of LPS (100 ng/ml) stimulation. Supernatants were centrifuged to remove cellular debris and stored at 70C until analyzed by ELISA. For intracellular cytokine analysis cells were treated with 1 l Golgi-plug containing Brefeldin A (BD Biosciences) and LPS (100 ng/ml) for 6 hrs at which point supernatants were collected and the remaining cells lysed for intracellular cytokine analysis. …

Retrograde and Transganglionic Labeling using Cholera Toxin b Subunit:

Cholera toxin b subunit (CTb) was used to retrogradely label the motor pools of selected forelimb muscles and to anterogradely (i.e., transganglionically) label muscle afferents as a means to help localize CST terminations. CTb preferentially labels myelinated afferents [18], [19]. Studies have shown a correspondence between CTb-labeled proprioceptive afferents and intra-axonally labeled group 1 afferents [20] and group 1 field potentials [21]. We performed multiple injections of CTb (11000, List Laboratories) unilaterally into the deltoid, elbow flexor, and the wrist extensor compartments (42.5 µL; 33 ga. Hamilton syringe). Our intent was to label selectively muscles that act at the same joint. …

Assay for Holotoxin Disassembly:

CT was appended to a GM1-coated SPR sensor slide as previously described [18]. PDI (0.1 mM) was then perfused over the CT-coated sensor in PBS containing 0.05% Tween 20, 1 mM GSH, and either grape seed or grape pomace extract. …

CTA1 Translocation and Secretion Assays:

HeLa cells exposed to GM1 and CT were processed as described above for the toxin transport assay, except (i) media samples were collected before lifting the cells from the plates; (ii) the cell pellet was resuspended in 1 mL HCN/digitonin buffer; and (iii) the cytosolic fraction was collected and diluted to a final volume of 1 mL in HCN buffer. …
