All animals were on the C57BL/6 genetic background unless otherwise specified. HuLangerin-Cre I-Aβ (10 (link)), huLangerin-Cre MyD88(6 (link)), huLangerin-DTA (11 (link)), mice have all been previously described. Rag1−/−, IL-6−/−, IL-1β−/−, MyD88/TRIF−/− and B6.129P2-Cxcr6tm1Litt were purchased from Jackson Labs (Bar Harbor, ME). IL-23−/− mice were a kind gift from Nico Ghilardi (Genentech, San Francisco CA). NLRP3−/− and ASC−/− mice were acquired from Millenium Pharmacerticals(12 (link)). All experiments were performed with 8–10 week old age- and sex-matched littermates. Mice were housed in specific pathogen free microisolator cages and fed irradiated food and acidified water. The University of Minnesota institutional animal care and use committee approved all animal protocols.
