Conjugation technologies are being developed to target lung tissue, tumors, and the central nervous system. The primary concern is the activation of the innate immune response, particularly through Toll-like receptors, which can cause inflammation or cytokine release.
Advancing Sirna Technology for Targeted Tissue Delivery
Targeted conjugates, such as GalNAc-siRNA complexes, exploit specific receptors on hepatocytes, allowing for non-viral delivery directly to the liver with high specificity. To overcome this, lipid nanoparticles (LNPs) and polymeric carriers are frequently used to protect the payload and facilitate endosomal escape.
A well-constructed sirna typically features a 19 to 21-nucleotide spacer sequence flanked by two-nucleotide overhangs. Delivery Challenges and Advanced Formulations Delivering sirna to the intended cells remains one of the biggest hurdles in clinical translation.
Advancing Sirna Technology for Targeted Tissue Delivery
Once loaded, the guide strand directs the complex to a complementary messenger RNA, leading to its cleavage and subsequent degradation. This sequence-specific cleavage effectively reduces the expression of the target protein without altering the genome.
