Many components of the immune system play diverse roles in lipid metabolism and vice versa. Macrophage immune functions, including pathogen clearance and apoptotic cell removal, are regulated by lipids but also generate effectors that impact on lipid homeostasis. Oxidized lipids, byproducts of the oxidative burst, activate nuclear receptors, which not only orchestrate lipid homeostasis but also cross-regulate NFκB-driven immune responses. Activation of macrophages leads to cytokine production and induction of the acute phase response, accompanied by systemic lipid changes. Lipoproteins and their components, as well as lipid transport molecules, are emerging as novel actors in innate immune defence.
