Adoptive transfer of immune cells

For the adoptive transfer of BMDCs, Itgax(CD11c)-DTR/EGFP-recipient mice (age 6–7 weeks, male) were intraperitoneally injected with 100ng diphtherin (DT) and administered with WT BMDC or Slc38a5−/− BMDC cells (1 × 106 cells suspended in 100 μL sterile PBS) via the ophthalmic vein. DT injection and cell transfer were performed every 3 days starting from one day prior to IMQ treatment, and 3 times of DT injection plus cell transfer were performed (Figure S4B). The mice in the control groups received injection of sterile PBS (100 μL). …

MOG-induced EAE in / 6 mice

The mice were immunized by subcutaneous injections of 200 μg myelin oligodendrocyte glycoprotein (MOG) (35–55) (Genemed Synthesis, San Francisco, CA) in complete Freund’s adjuvant, containing 1 mg M. tuberculosis, strain H37RA (CFA; Difco, Detroit, MI), divided among two sites draining into the axillary lymph nodes. Sham mice, that served as negative controls, were injected with complete Freund’s adjuvant without MOG (35-55). After immunization (day 0) and on day 2, the mice received intraperitoneal injections of 200 ng pertussis toxin (List Biological Laboratories, Campbell, CA) dissolved in phosphate-buffered saline (PBS).

Immunohistochemistry, image capture, and Imaris reconstruction

Mounted spinal cord sections were first incubated in PBS containing 0.1% Triton X (PBS-T) for 3 consecutive washes of 5 minutes each. Subsequently, spinal cord sections were incubated in 0.1% PBS-T solution containing primary antibodies and 10% heat-inactivated horse or donkey serum (Invitrogen) overnight at 4°C. Primary antibodies used were rabbit anti-DsRed (1:2000) [Clontech, 632496], guinea pig anti-vglut1 (1:1000) [Millipore, AB5905], goat anti-CTB (1:10 000) [List Biological Laboratories, 703], and chicken anti-parvalbumin (1:500) [sysy, 195006]. Following primary antibody incubation, spinal cord sections were washed with PBS for 15 mins (3x5min fresh solution). …

LPS transfection and cell viability measurement

To induce pyroptosis in Hydra cells, dissociated Hydra cells were seeded into 12-well plates (approximately 107 cells per well) and stimulated with CTB (20 μg/μl; List Biological Laboratories) plus ultrapure LPS (1 μg/μl; E. coli O111:B4, InvivoGen). For inhibitor treatment, Hydra cells were pretreated with 20 μM Z-VAD-FMK (Sigma-Aldrich) for 30 min before adding CTB plus LPS. For propidium iodide (PI) staining, PI (5 ng/ml; Thermo Fisher Scientific) was added into medium to detect the loss of cell membrane integrity. The cytotoxicity induced by overexpression of HyGSDME wild type and its truncation mutants in HEK293T cells was determined by a CytoTox 96 assay kit (Promega) to detect the lactate dehydrogenase release. Static bright-field images of pyroptotic cells were captured by Nikon A1R microscope and processed by ImageJ. …
