Immunizations and challenge in cotton rats:

Four to eight week old female cotton rats (Sigmodon hispidus) were immunized with vaccines consisting of 5µg RSV F protein previously described formulated in 5µg Cholera toxin [List Biological Laboratories, Campbell, CA; Cat. 100B], given two weeks apart. The vaccines were administered via a pipette directly to the mid-line of the right and left nostril in a volume of 10µl in sedated animals with ketamine/xylazine or isoflurane/oxygen anesthesia. …

Effect of MSCs on LPS-driven monocyte activation:

… To assess the immunomodulatory ability of MSCs cultured with either 10% FBS or 10% ePL culture media, a cytokine production assay was performed according to established protocols [35]. Equine MSCs (n = 3) at P6 were placed at the bottom of 12-well transwell plates at 100,000 cells/well and allowed to adhere for 12 h in the presence of their corresponding medium. The following day, medium was aspirated and replaced with 1.5 ml of RPMI-1640 supplemented with 10% DHS. Half a milliliter containing 400,000 equine monocytes (ratio 1:4) from the three individuals (n = 3) were added to each insert of a transwell plate with pore size of inserts 0.4 m (Corning, NY), stimulated with 50 ng/ml of E. coli 0111:B4 LPS (List Biologicals Inc.) and incubated at 37 C under 5% CO₂. At 6 and 18 h time points, cell culture supernatants were collected and assayed for the production of the proinflammatory cytokine tumor necrosis factor (TNF)- as an indicator of inflammatory responses [27].

Vivo Incubation of CT in a Ligated Ileal Loop

… The segment was then injected with 300 μl of either sterile physiological saline (composition in mM: NaCl 118, NaHCO3 25, D-glucose 11, KCl 4.8, CaCl2 2.5, MgSO4 1.2, NaH2PO4 1.0) as a control, or CT (12.5 ug/ml; List Biologicals, Campbell, CA, USA) in physiological saline. This concentration of CT is within the range that effectively induced changes in gastrointestinal motility in male mice (Balasuriya et al., 2016), increased the excitability of specific enteric neuronal subtypes in guinea pigs (Gwynne et al., 2009; Koussoulas et al., 2017), and increased secretion in rat and human intestine (Burleigh and Borman, 1997; Kordasti et al., 2006). …
