Codelivery of STAT3 and PD-L1 siRNA by hyaluronate-TAT trimethyl/thiolated chitosan nanoparticles suppresses cancer progression in tumor-bearing mice.

Summary: Scientists have created a tiny, smart delivery system to fight cancer. They built microscopic "nanoparticles" loaded with special genetic instructions (called siRNA). These instructions are designed to turn off two major shields that cancer cells use to grow and hide from the immune system. When tested on breast and skin cancer cells, and in mice, these tiny delivery vehicles successfully got inside the cells and stopped the tumors from growing and spreading. This new method shows great promise as a future cancer treatment!
