LXRa genomic binding in murine macrophages

Liver X receptors (LXRa and LXRß) are nuclear receptor transcription factors that play crucial roles in regulating metabolic and immune functions in macrophages. Both receptors are present in macrophages and exhibit significant sequence similarity, yet their specific roles in various macrophage models, especially in inflammatory contexts, remain underexplored. Prior research has demonstrated that ligand-activated LXRs can suppress the expression of pro-inflammatory cytokines in macrophages. Here, we explored the genomic landscape of LXRa under inflammatory conditions using BMDM lacking LXRb as previously described (de la Rosa et al 2024); we treated BMDM with synthetic LXR ligand GW3965 alone or in combination with lipopolysaccharide for 24h. Overall design: Chromatin immunoprecipitation DNA-sequencing (ChIP-seq) for nuclear receptor LXR-alpha in bmdm cells.
