GLP-1 Binding The EM structure of the GLP-1 apo receptor (i.e., receptor in the absence of any ligand), shows that the N-terminal domain adopts a closed or inactive conformation, where a cap-like structure blocks access to the peptide binding ( PDB ID 6ln2, Wu et al., 2020, Figure 4a)
Typical titration takes 4 to 6 months, starting at 0.25 mg and increasing by 0.25 mg every 4 weeks
Ozempic and Wegovy became cultural phenomena in 2023-2024, creating massive awareness of GLP-1 medications but also massive frustration with their cost ($1,000+ per month), injection format, and supply shortages
