“To study NLRP3 inflammasome activation based on caspase-1 activity, cells were cultured on coverslips and primed with LPS for 4 hours. Cells were stimulated with nigericin for 30 minutes followed by incubation with FLICA FAM-YVAD-FMK probe (ImmunoChemistry Technology LLC) for an additional 30 minutes and analyzed by fluorescence microscopy.”

“Active caspase-1 was measured in monocytes using the specific fluorescent probe FLICA-660 Caspase-1 Assay Kit (Immunochemistry Technologies) following the manufacturer’s instructions. For the determination of ASC specks and FLICA, monocytes were selected using anti-CD14 PE (clone 61D3, Tonbo Biosciences) or anti-CD14 APC-H7 (clone MφP9, BD Biosciences), respectively. Samples were analysed by flow cytometry using a FACS Canto (BD Biosciences) and the FCS express software (De Novo Software).”

“The FLICA 660 Poly Caspase Assay Kit (ImmunoChemistry Technologies, Minnesota, USA) was used to determine the presence of early caspase activation. This in vitro assay employs the fluorescent inhibitor probe 660-VAD-FMK to label active caspase enzymes in living cells. N2a cells (0.25–1·105) were incubated with exosomes (0.5–1·104 exosomes/cell) for 6 h at 37 °C. The cells were washed twice with PBS and resuspended in RPMI medium with 10% FBS before staining with 30 × FAM-VAD-FMK for 30 min at 37 °C. Cells were washed with 1 x…”

“The following day, plates were washed with PBS containing 0.05% Tween-20 and then blocked with Neptune Block (ImmunoChemistry Technologies, Bloomington, MN) for 2 h at 37°C. Plates were washed again prior to being loaded with 2-fold serial dilutions of mouse sera in duplicate (dilution range 1:200 to 1:25,600). Serum dilutions were carried out in Neptune Block. Plates were incubated at ambient temperature for 1 h prior to being washed, and then incubated with a 1:1,000 dilution of horseradish peroxidase (HRP) conjugated goat anti-mouse (SeraCare Life Sciences, Gaithersburg, MD) in Neptune Block for 1 h at ambient temperature.”

“Total ROS activity was measured using Intracellular Total ROS Activity Assay Kit (ImmunoChemistry Technologies, Bloomington, MN, USA). After 24 h of incubation of glioblastoma cells U-87 MG (ATCC, Manassas, VA, USA) with the test compounds in concentration 10 µg/ml, the medium was removed, the cells were washed twice with the cold PBS solution and the Assay Buffer (provided by the kit manufacturer) was added. Then, cells (at a density of 1 × 106 cells/ml) were treated with 10 µl of Total ROS green reagent and incubated for 1 h at 37 °C in a CO2 incubator. After incubation, the cells were subjected to a rinsing procedure using the Assay Buffer.”
