Experimental details: Western blot analysis was performed on whole cell extracts (20 µg lysate) of Mouse Spleen (Lane 1), Mouse Lung (Lane 2), Mouse Kidney (lane 3), A549 (lane 4) and Rat Heart (lane 5). The blots were probed with Anti-ICAM-1 Mouse Monoclonal Antibody (Product # MA5407, 1:250 dilution) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Secondary Antibody, HRP conjugate (Product # 62-6520, 1:4000 dilution). A 56 kDa band corresponding to ICAM-1 was observed across cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 12 % Bis-Tris gel (Product # NP0342BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate (Product # 32106).

Experimental details: Immunohistochemistry was performed on normal biopsies of deparaffinized Mouse kidney tissue. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:100 with a mouse monoclonal antibody recognizing CD54 (Product # MA5407) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

(C) Calcein-stained THP-1 monocyte adhesion on endothelial cells after incubation with NLRP3-YFP particles for 4 h measured by a fluorometric analysis and normalized to untreated cells in the culture medium (control). Two-sided unpaired t -test was used to analyze the data.

Experimental details: Figure 3 ALDH2 agonist Alda-1 reduces neurovascular dysfunction and inflammation in the acute phase (72 hours) of SCI in wild type mice. Representative whole spinal cords (A) and spectrophotometric quantification (B) of the amount of blood in homogenates, representative whole spinal cords (C) showing Evans blue dye extravasation into spinal cord and quantification of the Evans blue extravasation (D), levels of edema (spinal water content) (E), Western blot of the expression of ICAM-1 and GFAP (F) and densitometry of ICAM-1 and GFAP (G). Data are presented as the mean +- SD ( n = 7). *** P < 0.001, vs . Sham; + P < 0.05, ++ P < 0.01, vs . SCI (one-way analysis of variance with Tukey's post hoc test). Alda-1: N-(1,3-benzodioxol-5-ylmethyl)-2,6-dichlorobenzamide; ALDH2: aldehyde dehydrogenase 2; GFAP: glial fibrillary acidic protein; ICAM-1: intercellular adhesion molecule 1; SCI: spinal cord injury.

Experimental details: Brain Nrf2 and ICAM-1 expression in mice after 14 days of JUUL/TS exposure with or without MCAO. A Western blot images of Nrf2 expression in normoxic brain and contralateral & ipsilateral brain hemispheres 24 h after MCAO. B - D Quantification of brain Nrf2 expression normalized to beta-actin and expressed as relative to control (1.0) in normoxic, contralateral, and ipsilateral brain regions. E Western blot images of ICAM-1 expression in normoxic brain and contralateral & ipsilateral brain hemispheres 24 h after MCAO. F - H Quantification of brain ICAM-1 expression normalized to beta-actin and expressed as relative to control (1.0) in normoxic, contralateral, and ipsilateral brain regions. *P < 0.05; n = 9 for each group (B), n = 7, 7, and 6 for control, JUUL, and TS respectively ( C , D ), n = 9 for each group ( F ), n = 6, 5, and 5 for control, JUUL, and TS respectively ( G , H ). Cropped images from blots have been used in some cases to improve the clarity and conciseness of the presentation. The cropped images are delineated with white space; full-length blots developed by X-ray films are presented in Additional file 1 : Fig. S1
