Tumor necrosis factor superfamily member 10 mRNA (TNFSF10 mRNA)

Tumor necrosis factor superfamily member 10 (TNFSF10) mRNA encodes the TRAIL protein, a type II transmembrane cytokine that plays a critical role in the immune system's ability to identify and eliminate transformed or virus-infected cells. The mRNA itself has become a focus of therapeutic development, particularly in oncology, where it is delivered exogenously to induce the production of TRAIL protein within the tumor microenvironment. Once translated, the TRAIL protein selectively binds to death receptors DR4 and DR5, which are often overexpressed on cancer cells, triggering a signaling cascade that leads to programmed cell death (apoptosis) while sparing most normal cells. Current research focuses on utilizing lipid nanoparticles (LNPs) or modified mRNA platforms to enhance the stability and targeted delivery of TNFSF10 mRNA to overcome the limitations of recombinant TRAIL proteins, such as short half-life and poor bioavailability. This approach represents a potent strategy for cancer immunotherapy, aiming to restore or amplify the natural pro-apoptotic signals that tumors often evade.

Exogenous delivery of TNFSF10 mRNA via lipid nanoparticles or viral vectors leads to the intracellular translation and surface expression of the TRAIL protein, which subsequently binds to death receptors DR4 and DR5 on target cells to trigger the extrinsic apoptotic pathway.
