Early, efficient detection and treatment of rheumatoid arthritis using new delivery system

The results of a new study showed that tiny particles made of a biodegradable polymer (BNPs — biodegradable polymer nanoparticles) have the potential to enable early detection and efficient long-term treatment of rheumatoid arthritis (RA), with minimal side effects. By coating these particles with a peptide that is only able to target inflamed joint tissue, BNPs may be used to efficiently and selectively deliver drugs and diagnostic probes into arthritic joints.
