According to the reports, US researchers have developed a bran new medicinal peptide-based nanoparticle injection, which can not only controls the inflammation immediately but also reduce the destruction of cartilage once injected, which lowers the risk of osteoarthritis.

In the study, the nanoparticles were injected locally shortly after injury into the joint of the participants to penetrate into the injured cartilage to prevent cartilage breakdown that could eventually cause osteoarthritis, a form of arthritis, which causes due to the wearing down of flexible tissues at the ends of bones.

The researchers said that within 24 hours it worked in taming the inflammation in joint.

The Associate Professor of the Washington university in St. Louis in the United States, Christine Pham said, “These nanoparticles remain in the joint longer (than the traditional anti-inflammotory drugs) and help prevent cartilage degeneration.”

Another professor Samuel Wickline of the Washington University added, “The nanoparticles are injected directly into the joint, and due to their size, they easily penetrate into the cartilage to enter the injured cells.”

The new injection of nanoparticles contains peptide derived from a natural protein called melittin that has been modified to enable it to blind to a molecule called small interfering RNA (siRNA).
