Results – Antagonism Does Not Involve Inhibition of Nucleic Acid Uptake or Modulation of Endosomal pH:

Mouse RAW 264.7 cells transfected with an NF-Bresponsive luciferase reporter were stimulated by CpG2006 DNA, SL4 RNA, CL-097, or LPS. Stimulation by CpG2006 or SL4 RNA, but not by LPS or CL-097, was completely suppressed with 100 nM of AT791 or E6446…

EAE induction and assessment:

Six- to eight-week-old male B6 mice were injected s.c. in the back with 50 µg of MOG₃₅₅₅ peptide emulsified in incomplete Freund’s adjuvant supplemented with heat-inactivated Mycobacterium tuberculosis H37RA. Pertussis toxin (200 ng per mouse) dissolved in PBS was administered i.v. on the day of immunization and 48 h later. …

… SEB signals or IL-17A-positive cells were counted per mm of basement membrane under high-powered field (HPF, 400) at three different sites in the tissue. Reagents and cell culture. SEB was obtained from List Biological Laboratories INC. (Campbell, CA, USA). …

Neuronal tracing:

For tracer injections into the sciatic nerve to evaluate nerve regeneration, rats were anesthetized at 5 weeks post-spinal nerve injury with 4% isofluorane and the sciatic nerves at mid-thigh region ipsilateral to spinal nerve injury were exposed under aseptic conditions. A 5 l solution of 0.5% CTB (Cholera Toxin B subunit, low salt; List Labs)…were injected into the sciatic nerve at 35 sites using a Hamilton syringe.

Immunohistochemistry:

Frozen sliced sections of DRG (10 m) and spinal nerve (10 m) were serially mounted. Selected sections (at least 120 m apart from each other if from the same DRG) were incubated with primary reagents 24 h at 4 C, and with the secondary antibody for 2 hrs at room temperature. Primary antisera were: polyclonal goat anti-CTB IgG (1:5,000; List, CA),…
