PET imaging to find and track harmful lung inflammation via CMKLR1

CMKLR1-Targeted Molecular Imaging of Inflammation as a Precision Medicine Tool in Acute Lung Injury and Fibrotic Lung Diseases

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11181300

A new PET scan tracer that targets CMKLR1 is being developed to find and track harmful lung inflammation in people with acute lung injury, ARDS, and fibrotic lung diseases.

What this research studies

This project develops a PET imaging tracer that binds the CMKLR1 receptor, which is increased on inflammatory cells that drive lung fibrosis. Researchers will test the tracer in animal models of acute lung injury and fibrosis to measure lung inflammation and response to therapies. They will also examine CMKLR1 levels in lung tissue from people with COVID-19 and various fibrotic lung diseases compared with healthy controls to understand clinical relevance. The goal is to create a noninvasive imaging tool that could predict who will worsen and show early treatment effects.

Who could benefit from this research

Good fit: People with acute lung injury, ARDS, or fibrotic lung disease (including post-COVID-19 lung damage) would be the likely candidates for future imaging using this tracer.

Not a fit: People without lung inflammation or with unrelated medical problems are unlikely to benefit from this imaging approach.

Why it matters

Potential benefit: If successful, this could give doctors a noninvasive way to see and measure lung inflammation to guide treatment choices and predict disease progression.

How similar studies have performed: Early animal data show increased lung uptake of the new tracer, but CMKLR1-targeted PET is a novel approach with limited prior use in human fibrotic lung disease.
