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. …

Analysis of axonal regeneration following SCI.

Adult 8-week-old cre+Pfn1 mice and 15-week-old female C57BL/6 mice were deeply anesthetized with isoflurane. Laminectomy was performed at the thoracic T8 to T9 level and the spinal cord was cut using a micro feather ophthalmic scalpel (Feather, Safety Razor Co). For CL experiments, animals were subjected to a sciatic nerve transection 1 week prior to SCI. In cre+Pfn1 mice, analysis of dorsal column axon regeneration after either SCI or CL was performed 4 weeks after injury. Dorsal column axons were traced by injecting 2 μL of 1% CT-B (List Biologicals, 103B) with a 10-μL syringe (Hamilton) into the left sciatic nerve 4 days prior to euthanasia (day 24 after injury). On day 28, mice were perfused with 4% PFA and the spinal cords were postfixed for 1 week at 4°C and later cryoprotected in 30% sucrose. Serial tissue sagittal cryosections (50 μm thickness) were collected for free-floating immunohistochemistry. Sections were incubated overnight at 4°C with goat anti–CT-B primary antibody (1:30,000; List Biologicals, 703).
