Neuronal receptors ligand receptor complex

Ligand-receptor complexes that do not dissociate in the EEs have different fates. In some cells, they may be returned to the same plasma membrane compartment from which they originated, whereas in polarized cells such as endothelial cells or astrocytes they can be moved to a different plasma membrane domain, resulting in transcytosis. In other cases, the complexes go to LEs and lysosomes for degradation. In neurons, these vesicles may serve as signaling organelles that are transported from the EEs back to the cell body where they influence gene expression [71].
