Central mechanisms by which peripheral GLP-1RAs may reduce appetite or induce nausea. Peripheral GLP-1 or GLP-1RAs may interact with appetite-regulating regions of the brain via gaps in the blood-brain barrier, via tanycyte uptake, or indirectly via the nodose ganglia. The effects to slow gastric emptying, induce nausea, and reduce energy intake are independent. AgRP, agouti-related peptide; AP, area postrema; ARC, arcuate nucleus; BBB, blood-brain barrier; CART, cocaine- and amphetamine-regulated transcript; H, hypothalamus; lPBN, lateral parabrachial nucleus; NAc, nucleus accumbens; NPY, neuropeptide Y; NTS, nucleus tractus solitarius; POMC, proopiomelanocortin; VTA, ventral tegmental area.
