Cell-penetrating peptides as a delivery system for oligonucleotides

Drug Discovery World

Oligonucleotides act on the RNA level through different molecular pathways, but there is a major drawback when using them as drugs: their poor bioavailability and cellular uptake. Ensuring that the CPP can escape this endosomal compartment is crucial for its bioavailability and bioactivity properties.

Considerations for Neuroscience Trials with Intrathecal Delivery and Other Methods of Direct CNS Administration

XTalks

A major obstacle for CNS drug developers is the inability to target therapies to the CNS broadly (for instance, a therapy that is orally bioavailable as a pill and has difficulty crossing the blood-brain barrier) and certain CNS regions more specifically. What About Small Proteins and Antibodies Reaching Extracellular CNS Targets?
