ABSTRACT
Thromboembolic conditions are a leading cause of death worldwide, and deep vein thrombosis (DVT), or occlusive venous clot formation, is a critical and rising problem that contributes to damage of vital organs, long-term complications, and life-threatening conditions such as pulmonary embolism. Early diagnosis and treatment are correlated to better prognosis. However, current technologies in these areas, such as ultrasonography for diagnostics and anticoagulants for treatment, are limited in terms of their accuracy and therapeutic windows. In this work, we investigated targeting myeloid related protein 14 (MRP-14, also known as S100A9) using plant virus-based nanoparticle carriers as a means to achieve tissue specificity aiding prognosis and therapeutic intervention. We used a combinatorial peptide library screen to identify peptide ligands that bind MRP-14. Candidates were selected and formulated as nanoparticles by using cowpea mosaic virus (CPMV) and tobacco mosaic virus (TMV). Intravascular delivery of our MRP-14-targeted nanoparticles in a murine model of DVT resulted in enhanced accumulation in the thrombi and reduced thrombus size, suggesting application of nanoparticles for molecular targeting of MRP-14 could be a promising direction for improving DVT diagnostics, therapeutics, and therefore prognosis.
