EAE induction.

Adult mice were injected s.c. in each hind leg with 50 μg of MOG35–55 (Peptide Synthesis Facility, University of Alberta) emulsified in 100 μl CFA (MilliporeSigma). Animals received 0.3 μg/ml of pertussis toxin injected i.p. Injection of pertussis toxin (List Biological Laboratories) occurred on the day of induction with MOG35–55, with subsequent infection 48 hours later. Control animals were immunized with CFA and PBS (1:1) and pertussis toxin, as above. …

Induction of EAE and treatments:

… EAE was induced using a modification of our previously reported method [8, 9]. In brief, 8 to 10 weeks old C57BL/6 female mice were subcutaneously injected with 100 µg myelin oligodendrocyte glycoprotein (MOG) ₃₅₅₅ emulsified in complete Freund’s adjuvant (CFA) supplemented with intraperitoneal injections of 400 ng pertussis toxin (List Laboratories, Campbell, CA, USA) on days 0 and 2. …

Induction of EAE and clinical evaluation:

For the induction of EAE, wild-type (WT) and Slfn8^/ mice (C57BL/6 and 129SV mixed background) were immunized subcutaneously with 150 µg of myelin oligodendrocyte glycoprotein (MOG) peptide (MOG_35-55) (Anaspec, Fremont, CA, USA) emulsified in CFA (day 0). After immunization, the mice were intraperitoneally (i.p.) injected with 200 ng of pertussis toxin (List Biological Laboratories, Campbell, CA, USA) on days 0 and 2. …

Immunization of Mice:

… Five mice per group were anesthetized with ketamine and immunized three times at a 2-week interval by i.n. injection of 20µg of ovalbumin (OVA; Sigma, St. Louis, MO) alone, or mixed with 10µg of TCTA1T and TmCTA1T, or 2µg of CT (List Biological Laboratories Inc., Campbell, CA). …

Online supplemental material:

Fig. S1 shows that Tg, but not Tu, BFA, or MG132, induces IRE1 to undergo phosphorylation at S729. Fig. S2 shows that KIRA6 rapidly suppresses SubAB-induced S729 phosphorylation of IRE1 and that Shiga toxins, cholera toxin, and pertussis toxin do not induce S729 phosphorylation even when used at high concentrations. …
