    Obesity drives cardiovascular disease through chronic meta-inflammation, linking nutrient excess to NLRP3 inflammasome activation in macrophages.

  • 2

    Inhibitory phosphorylation of SAMHD1 leads to cytosolic dNTP accumulation, mitochondrial import, and NLRP3 hyperactivation in obesity.

  • 3

    The SAMHD1–dNTP–mtDNA–NLRP3 axis may set macrophage inflammatory tone and contribute to obesity-associated cardiovascular pathology.

  • 4

    Nucleotide metabolism reprogramming offers a new framework for understanding immunometabolism and potential therapeutic interventions.

  • 5

    Targeting SLC25 transporters, SAMHD1-preserving kinases, and mitochondria-targeted antioxidants may address obesity-driven cardiovascular risk.
