Authors' conclusion

Integrating multiomics data, we found a proteomic signature of IL-6 signaling activation and mediators of its effects on cardiovascular disease.

Study context

Population
Genetic data from 522,681 individuals; INTERVAL cohort proteomics; population-based study; human atherosclerotic lesion samplesINTERVAL n=3301
Participants
522,681 participants
Comparison
Genetically proxied IL-6R inhibition and its proteomic mediators

Main finding

As reported in the abstract

Effects of genetically proxied IL-6 signaling on circulating proteins and proteomic mediators of its effects on CAD, large artery atherosclerotic stroke and PAD

Significant effects of genetically proxied IL-6 signaling on circulating proteins (cytokine production/regulation, immune cell recruitment/differentiation)

70

Genetically proxied CXCL10 levels associated with risk of CAD, large artery atherosclerotic stroke and PAD; share of effects of genetically downregulated IL-6 signaling mediated by decreases in CXCL10

up to 67%

Further findings

Midlife circulating CXCL10 and incident CV events (population-based study, n=1704) · 20 years

Higher midlife CXCL10 associated with a larger number of CV events

CXCL10 expression in human atherosclerotic lesions

Higher expression correlated with a larger lipid core and a transcriptomic profile of immune cell infiltration, adaptive immune activation and cytokine signaling
