Injection of a retrograde tracer into the parafacial respiratory group

In five animals, pFRG injections of the retrograde tracer cholera toxin b (CTb, 1% in deionized water; List Biological, Campbell, CA) were unilaterally performed. For pFRG injections, the dorsal surface of the brain was exposed via an occipital craniotomy. The stereotaxic coordinates for targeting the pFRG were 2.7 mm caudal from lambda, 2.6 mm lateral from midline, and 8.7 mm ventral from the skull surface. The CTb (30 nl) was delivered by pressure through glass pipettes. …

C. difficile in vitro Vero cell cytotoxicity assay

… The cytotoxic titer was defined as the reciprocal of the highest dilution that produced rounding in 80% of Vero cells for each sample. Vero cells treated with purified C. difficile toxins (A and B) and antitoxin (List Biological Labs, 152C and 155C; TechLabs, T5000) were used as controls.

Infections and stimulations

MDDCs were infected or stimulated with innate agonists between day 4 and day 6 after differentiation. For infections with HIV-1 and related lentiviruses, except where noted otherwise, Vpx+ virus-like particles were used to overcome virus restriction (1 mL supernatant for 1 × 10ˆ7 cells) (Johnson et al., 2018, Manel et al., 2010). MDDCs were counted on day 4 and resuspended at 800,000 cell per ml in fresh medium with GM-CSF, IL-4, and polybrene (1 μg/ml) and then reseeded into appropriate culture vessels. For most assays, MDDCs were infected at a density of 800,000 cells per ml by diluting virus in MDDC media (without cytokines or polybrene) to a final volume normalized to controls. Innate and inflammatory stimuli were used at the indicated concentrations: poly(I:C) (InvivoGen, 10 μg/ml); LPS (List Biological Laboratories, INC, 1 ng/ml).

Antibody selection in microtiter plate

The antibody selection was performed as described previously with modifications33. In brief, for the panning procedure, the antigen was immobilized on a Costar Highbinding 96 well plate (Corning, New York, USA). 1 µg of DT (List Biological Laboratories, Campbell, USA) was diluted in PBS (137 mM NaCl; 1.76 mM KH2PO4 × 2 H2O) and coated in the wells at 4 °C overnight. …
