Induction of monophasic or relapsing–remitting EAE

Monophasic EAE was induced in 8–10-week-old female C57BL/6 mice by subcutaneous injection of 300 µg of MOG35-55 peptide (Biomatik, USA, LLC; Sequence: MEVGWYRSPFSRVVHLYRNGK) emulsified in Complete Freund’s Adjuvant (CFA) containing 500 µg of heat-inactivated Mycobacterium tuberculosis (Difco). On Days 0 and 2, 500 ng pertussis toxin (List Biologicals) was administered intraperitoneally. …

EAE induction, clinical evaluation and GK treatment

For EAE induction, female mice (10-12 weeks old) were immunized subcutaneously with 300μg MOG35-55 (Chinapeptides, China) emulsified in complete Freund’s adjuvant (CFA) (100μg/mouse, supplemented with 5mg/ml heat-inactive Mycobacterium tuberculosis H37RA) and injected intraperitoneally with 300ng pertussis toxin (List Biological Laboratories, USA) at the same time of immunization and again 48h after immunization. …

EAE model

… C57BL/6J mice were anesthetized by sevoflurane, and then subcutaneously injected with 100 μL MOG35-55 (3 mg/mL)/IFA (H37RA 4 mg/mL) (catalog: 231141, Difco Laboratories, USA) into the two sides of the upper part of the back on day 0. The mice were intraperitoneally (i.p.) injected with 50 μL of pertussis toxin (PTX) (0.5 μg/100 μL) (catalog: 180, List Biological Labs, Inc.). Forty-eight hours after the injection, the mice were injected with 50 μL of PTX for a second time. …

Induction of EAE.

EAE was induced as previously described (15). Female SJL/J mice (8–12 weeks) were obtained from Janvier SAS. A total of n = 35 mice in 6 cohorts were used in the study. Mice were immunized s.c. with 250 μg PLP139–151 (Pepceuticals Ltd.) and 800 μg mycobacterium tuberculosis H37Ra (Difco), and they were administered 200 ng of pertussis toxin (List Biological Laboratories) on d0 and d2. …

CD11bDTR mice were anesthetized by isoflurane and 1 μL DT solution (20 ng/μl) or saline was injected into the lateral ventricle of the mice. At 12 h after DT-injection, mice were subjected to 3 times FS to test seizure latency and then decapitated for Iba-1 immunostaining, or mice were anesthetized by isoflurane for flow cytometry. …

… For canonical inflammasome stimulations, overnight (ON) IFNγ‐primed BMDMs were then prestimulated with PAM3CSK4 (InvivoGen, 100 ng/ml) for 4 h to induce pro‐IL1β expression. Then, Nigericin (NLRP3 activator, 40 μM, InvivoGen), dA:dT (AIM2 activator, 1 μg/ml, InvivoGen), TcdB toxin (PYRIN inducer, 0.05 μg/ml, List Biological Laboratories) or flagellin (NLRC4 trigger, 1 μg/ml, InvivoGen) was used to stimulate various canonical inflammasomes. Both flagellin and poly(dA:dT) were transfected into cells using FuGeneHD (Promega) transfection reagent in Opti‐MEM culture medium. When specified, P. aeruginosa (PAO1) and S. Tm strains (SL1344) (MOI 5) were used to trigger NLRC4 inflammasome response …
