Longitudinal Ga-DOTA-ECL1i PET/CT in K/BXN serum transfer arthritis mice shows joint CCR2+ monocyte/macrophage recruitment rises in acute disease and declines with resolution.
- Why it matters: Early CCR2+ inflammatory monocyte and macrophage infiltration is linked to rheumatoid arthritis pathogenesis, but it has lacked a noninvasive way to track over time.
- What they did: The study performed repeated Ga-DOTA-ECL1i PET/CT in K/BXN STA mice and validated uptake with biodistribution, autoradiography, histopathology, immunofluorescence, microCT, cytokines, clinical scoring, and pain behavior.
- The result: Tracer signal in inflamed joints matched CCR2 monocyte/macrophage infiltration, synovial inflammation, cartilage damage, local CCL2 elevation, and mechanical allodynia, and PET uptake correlated with ankle swelling, severity, pain, and paw CCL2, peaking before progressive structural bone remodeling.
