Abstract

Atherosclerosis (AS) is a major contributor to cardiovascular diseases worldwide, and alleviating inflammation is a promising strategy for AS treatment. Here, we report molecularly engineered M2 macrophage‐derived exosomes (M2 Exo) with inflammation‐tropism and anti‐inflammatory capabilities for AS imaging and therapy. M2 Exo are derived from M2 macrophages and further electroporated with FDA‐approved hexyl 5‐aminolevulinate hydrochloride (HAL). After systematic administration, the engineered M2 Exo exhibit excellent inflammation‐tropism and anti‐inflammation effects via the surface‐bonded chemokine receptors and the anti‐inflammatory cytokines released from the anti‐inflammatory M2 macrophages. Moreover, the encapsulated HAL can undergo intrinsic biosynthesis and metabolism of heme to generate anti‐inflammatory carbon monoxide and bilirubin, which further enhance the anti‐inflammation effects and finally alleviate AS. Meanwhile, the intermediate protoporphyrin IX (PpIX) of the heme biosynthesis pathway permits the fluorescence imaging and tracking of AS.

  • Molecularly engineered M2 macrophage-derived exosomes may contribute to treating atherosclerosis by suppressing inflammation via chemokine receptors and inflammation inhibitory cytokines secreted by M2 macrophages.

    “Wu et al. reported that molecularly engineered M2 macrophage-derived exosomes may contribute to treating atherosclerosis by suppressing inflammation via chemokine receptors and inflammation inhibitory cytokines secreted by M2 macrophages.”
  • Encapsulated hexyl 5-aminolevulinate hydrochloride can diminish inflammation effectively by intrinsic biosynthesis and metabolism of heme.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
