Figure A6.
IL1β analysis after 3 h pre-treatment with Nigericin or LPS followed by 6 h stimulation with PHF6/aPHF6. The treatment with unaggregated PHF6 or aggregated aPHF6 lead to no secretion of IL1β. LPS was used as a positive control, which also lead to no secretion. For NLRP3 priming, cells were pre-treated with Nigericin or LPS for 3 h followed by PHF6 or aPHF6 treatment for 6 h. Only the combination of Nigericin and LPS stimulation increased the IL1β secretion into the supernatant. Only minor levels were found after Nigericin only, and in combination with aPHF6 or PHF6. Similar levels were found after LPS pre-treatment as a priming agent.
