Itaconate mimetics inadequately represent endogenous itaconate, a negative regulator of innate immune-driven pro-inflammatory cytokines. We present a CRISPR-Cas9 protocol to delete a 4-nucleotide region in the immunoresponsive gene 1 (IRG1), ablating ACOD1 (the itaconate-producing enzyme) in THP-1 cells. We describe the functional validation of ACOD1 deletion using immunoblotting, ELISA, and liquid chromatography-mass spectrometry (LC-MS) quantification of itaconate, enabling the study of endogenous itaconate in THP-1 macrophages. For complete details on the use and execution of this protocol, please refer to Bourner et al.1.
