Blocking a heart enzyme with an antibody to prevent heart failure after a heart attack

Targeting a ectonucleotidase in the heart with a monoclonal antibody to prevent post-infarct heart failure

NIH-funded research University of California Los Angeles · NIH-11126764

An antibody that blocks an enzyme called ENPP1 in the heart aims to reduce scarring and lower the chance of heart failure after a heart attack.

What this research studies

You had a heart attack and your heart responds by making an enzyme called ENPP1 that fuels inflammation and scar formation. Researchers at UCLA are using a lab-made monoclonal antibody to block ENPP1 in laboratory and animal models to see if this reduces damage and preserves heart muscle. The team combines genetic loss-of-function data with antibody treatment experiments to measure inflammation, scarring, and heart function after injury. If these preclinical results are promising, the work could move toward human testing and new treatments to prevent post-heart-attack heart failure.

Who could benefit from this research

Good fit: People who recently had a myocardial infarction (heart attack) and are at risk of adverse remodeling or future heart failure would be the ideal candidates for related future trials.

Not a fit: People without a recent heart attack or those with long-standing, advanced chronic heart failure are unlikely to benefit from this prevention-focused approach.

Why it matters

Potential benefit: If successful, this approach could reduce scar formation after a heart attack and lower the risk of developing heart failure.

How similar studies have performed: Targeting remodeling pathways after heart attack has shown promise in animal models and some human trials for other targets, but ENPP1-directed antibody therapy is a novel and largely preclinical approach.
