Delivering RNA-Targeted Medicines Deep Within the Nervous System
Preliminary research has demonstrated that investigational RNA-targeted medicines can penetrate tissues throughout the central nervous system (CNS) and are active across a wide range of cell types in the central nervous system.1-6 This offers the opportunity to develop RNA-targeted medicines for many types of neurologic diseases.1-4
RNA-targeted investigational medicines can be delivered to the spinal cord and deep regions within the brain, including the hippocampus, pons, and amygdala.1-4

CNS, central nervous system; PBS, phosphate-buffered saline; RTID, RNA-targeted investigational drug; RTM, RNA-targeted medicine.
Research in animal models has shown investigational RNA-targeted medicines are active in neurons, microglia, astrocytes, and oligodendrocytes.1-4
In human patients, investigational RNA-targeted medicines have been shown to distribute within the CNS.7
