BALB/c and C57BL/6 mice (female, 6–8 weeks old) were purchased from Jackson Laboratories (Bar Harbor, Maine, USA). A TFEBflox mouse line was generated using the ES cells from EUCOMM depository in Europe, which are the same cells used for generation of liver-specific TFEB knockout mice.24 (link) LysM-Cre mice were purchased from Jackson Laboratories and crossed with TFEBflox mice to generate MΦ-specific TFEB knockout (MΦ-TFEB-/-) mice. MΦ-specific TFEB transgenic (MΦ-TFEBtg) mice were generated and characterized previously.25 (link) Female FVB/N mice were bred with male heterozygous C3(1)/SV40Tag mice (a gift from Dr Jeffrey Green, National Cancer Institute). All mice were housed in the University of South Carolina or Washington University in St. Louis Animal Research Facilities.
