Background: Lipocalin 2 is a recently characterized adipokine/cytokine known to be a critical regulator of metabolic homeostasis. Results: Lcn2 deficiency impairs BAT activation by reducing peroxisomal and mitochondrial oxidation of lipids and the recruitment of functional brown adipocytes. Conclusion: We demonstrate a novel role of Lcn2 in oxidative metabolism and BAT activation via a nonadrenergic pathway. Significance: Our findings advance understanding of the adrenergic independent mechanism for BAT activation.
