Sugar-Coated Peptides: Glycosylation as a New Way to Get Neuropeptides Into the Brain

Attaching sugar molecules (glycosylation) to opioid and other neuropeptides improved their blood-brain barrier penetration and stability, enabling peripherally administered peptides to reach the brain — a new drug delivery paradigm.
