Monocytes and macrophages articles from across Nature Portfolio

Contemporary tools to predict cardiovascular risk lack accuracy on an individual-patient level. The use of single-cell RNA sequencing to identify specific leukocyte patterns might overcome some of these limitations, propelling us towards a precision medicine approach.

Glycolysis provides building blocks for the proinflammatory activation of macrophages and simultaneously generates pyruvate. In this issue of Nature Metabolism, Ran et al. provide evidence that the transport of pyruvate to fuel the Krebs cycle in the mitochondria is not required in the inflammatory response.

Copper(ii) ions promote the metabolic and epigenetic remodelling of macrophages towards a pro-inflammatory state. A copper-binding metformin dimer showed promising results in mouse models of inflammation.

Clonal haematopoiesis of indeterminate potential (CHIP) is defined as an expansion of mutant blood stem cells in individuals without haematological malignancies. CHIP is linked to an increased risk of non-cancerous disorders such as atherosclerotic cardiovascular disease, possibly because mutant innate immune cells have pro-inflammatory phenotypes. Prospective studies are needed to determine whether individuals with CHIP might benefit from anti-inflammatory therapies.
