Study Design

This single-center, randomized, double-blind, placebo-controlled, full-factorial single-dose study was conducted between December 2016 and December 2017 in subjects in whom pyrexia was induced by intravenous (IV) administration of a reference standard endotoxin (RSE; ClinicalTrials.gov identifier: NCT02761980). In this standardized model, fever was induced by endotoxin (gram-negative bacterial lipopolysaccharide) derived from Escherichia coli O113, which was developed as a national biological reference standard in 1976 by the National Institute of Allergy and Infectious Diseases and the US Food and Drug Administration.17 The RSE used in this study was a new lot supplied by List Biological Laboratories, Inc. (Campbell, California). …

Experimental Autoimmune Encephalomyelitis

For MOG35–55 induced EAE, age (8–12 weeks old) and gender matched mice were subcutaneously immunized (s.c.) with 50 μg of MOG35–55 peptide (MEVGWYRSPFSR VVHLYRNGK, AnaSpec) and 500 μg of M. tuberculosis (Difco) emulsified in IFA (Difco). In addition, the mice were administrated 200 ng of Pertussis Toxin (List Biological Laboratories) intraperitoneally (i.p.) on days 0 and 2, respectively. For adoptive transferred EAE, 2D2 CD4+ T cells were differentiated under pathogenic Th17 differentiation conditions for 4 days and re-stimulated in fresh medium in the presence of plate-bound anti-CD3 (2 µg/ml) and anti-CD28 (2 µg/ml) antibodies for 2 days. Live cells were purified as described. Approximately 1 × 106 purified cells were i.v. injected into Rag1−/− mice. Approximately 200 ng of Pertussis toxin (List Biological) was injected intra-peritoneal (i.p.) on days 0 and 2 after T cell transfer. For induced SKI expression in adoptive T cell transfer induced EAE, tamoxifen (TMA group) or corn oil (Control group) were injected intraperitoneally at days 1 and 3 after EAE elicitation as illustrated. …

EAE induction

To induce EAE, a 1:1 incomplete Freund’s adjuvant (IFA) to PBS emulsion was prepared with final concentrations of 2 mg/ml desiccated Mycobacterium tuberculosis (Difco 231141) (to make complete Freund’s adjuvant, CFA) and 0.5 mg/ml myelin oligodendrocyte (MOG) peptide 35-55 (Genscript RP10245). Three injections were administered s.c. in the back skin (100 μl per site) such that each mouse received 150 μg total MOG. At the time of MOG immunization and 1 d later, 200 ng pertussis toxin (List Biological 181) was injected i.p. …
