University of South Florida College of Medicine researchers found that an antiviral treatment combining nanoparticle and gene silencing technologies thwarts attacks of respiratory syncytial virus (RSV) — a virus associated with severe bronchitis and asthma.
The researchers developed nose drops containing vectors capable of producing small fragments of RNA (siRNA). These fragments were encapsulated within chitosan nanoparticles — biodegradable particles that stick to mucous-producing cells lining the lungs. The… read more
