Mice

Mice used included C57BL/6J (Charles River, #027), Tlr4 KO (Jackson Laboratory, #029015), Tlr4 floxed (Jackson Laboratory, #024872), iDTR and Mcpt5-Cre + (provided by Axel Roers, University of Technology, Dresden, Germany). All mice were used between 6 and 10 weeks. For mast cell depletion in Mcpt5-Cre + x iDTR mice, 8-week old mice were given 200 ng Diphtheria Toxin (DT, Unnicked, from Corynebacterium diphtheriae, List Biological Laboratories) per mouse intravenously once a day for 5 consecutive days prior to intradermal ear immunization. Mcpt5-Cre (- x iDTR mice were used as littermate controls. Control mice were also injected with DT to control for off target effects caused by DT. To generate mast cell-specific TLR4-deficient mice, Mcpt5-Cre + mice were crossed with Tlr4-floxed mice. Cre-non-expressing animals were used as littermate controls. ) per mouse intravenously once a day for 5 consecutive days prior to intradermal ear immunization.

Studies with Primary Tracheal Basal Epithelial Cells

Primary mouse tracheal basal epithelial cells (MTECs) were isolated from tracheas of either young (2 mo) or old (13–16 mo) wild-type (WT) C57BL/6J mice (Jackson Laboratories, Bar Harbor, ME) using overnight incubation with 0.1% protease 14 (Sigma-Aldrich, St. Louis, MO), as previously described (38, 39). Briefly, dissociated MTECs were propagated on a rat tail collagen I gel (BD Biosciences, San Jose, CA) in DMEM/F12 media (Invitrogen, Grand Island, NY) supplemented with 20 ng/mL cholera toxin (List Biological Laboratories, Campbell, CA), …

EAE model studies

The EAE model was induced in both wild type and hCXCR2 knock-in mice using synthetic myelin oligodendrocyte glycoprotein peptide (MOG35-55, MEVGWYRSPFS RVVHLYRNGK; GenScript). Briefly, mice were s.c. injected with an emulsion of 100 μg MOG35-55 peptide mixed with complete Freud’s adjuvant (IFA, #vac-ifa, InvivoGen) containing 400 μg Mycobacterium tuberculosis H37 Ra (#231141, Difco). A total of 400 ng pertussis toxin (#180, List Biological) were i.p. injected on the same day of MOG35-55 immunization and a second time at 48 h later. …

Light microscopy immunofluorescence histochemistry

For CTb- and FG-injected rats, sections containing Vpdm plane were selected for immunofluorescence staining of neuronal nuclei (NeuN)/CTb/FG and NeuN/CTb/VGLUT1, respectively. The experimental procedures were as follows: (i) rabbit anti-VGLUT1 IgG (1:500; Synaptic System)/rabbit anti-FG IgG, mouse anti-NeuN IgG (1:1000; Millipore), and goat anti-CTb IgG (1:2000; List Biological) were used to incubate slices at room temperature overnight, …
