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. …

DT List Biological Laboratories Cat. #150

Microglia depletion and dissociation

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 …

Induction of myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis

To induce EAE, all mice were immunized with MOG35–55 peptide (MEVGWYRSPFSRVVHLYRNGK; CelTek Bioscience, Nashville, TN) emulsified in an equal volume of complete Freund’s adjuvant (CFA; BD Difco, Franklin Lakes, NJ) and pertussis toxin (Ptx; List Biological Laboratories, Campbell, CA). Mice were anesthetized with isoflurane, and MOG35–55:CFA (100 μL; 3 mg/mL) was subcutaneously injected on each hind flank (200 μL total/mouse) on day 0. Ptx (200 μL; 2.5 μg/mL) was administered intraperitoneally (IP) on day 0 and day 2 post-MOG immunization (dpm). …
