In recent years, advances in cryo-electron microscopy (cryo-EM) have enabled structural determination of a large number of class B1 GPCRs bound to their endogenous agonists, and coupled to G s , including that of the GLP-1R, which confirm engagement of these peptides with both the ECD and the TMD 10,11,12,13,14,15,16,17,18,19,20,21

The rise of GLP-1 receptor agonists for use in type 2 diabetes Of the non-insulin treatments available for treating T2D, GLP-1 RAs offer the greatest reductions in HbA 1c , with more recent long-acting GLP-1 RAs matching, or even exceeding, glycaemic improvement achieved with basal insulin in T2D (Nauck et al, 2021)
