Inhibition of glutathione synthesis as a chemotherapeutic strategy for trypanosomiasis
GIP receptors (GIPRs) are highly enriched in oligodendrocytes within the hypothalamic median eminence, and activation of these GIPRs regulates oligodendrocyte survival and myelin plasticity - this process enhances the entry of GLP-1R agonists into the brain via two key pathways: upregulating vascular endothelial growth factor A (VEGF-A) to increase blood-brain barrier permeability and facilitating GLP-1R agonist traversal of myelinated neuronal axons to target hypothalamic nuclei involved in energy homeostasis, including the ARC and PVN [81]
