At the residue level, signaling initiation by either peptide 20, tirzepatide or endogenous peptide hormones rendered a common arrangement of residue contacts for the three receptors, including the reorganization of the central polar network that located just below the peptide binding site, opening of the hydrophobic packing to favor the formation of the TM6 kink at the PXXG motif and the rearrangement of two polar networks (HETX motif and TM2-6-7-helix 8) at the cytoplasmic face 33,34

These enzymes catalyze the reduction of H2O2 by GSH to H2O and GSSG
Slows gastric emptying: Results in slower digestion, contributing to better post-meal glucose and appetite control
Interestingly, during this developmental phase, astrocytes have not yet encapsulated the vasculature, allowing microglial processes to contact the endothelium, facilitating more direct interactions between microglia and the blood vessels (Mondo et al., 2020)
