Abstract/OtherAbstract:
Following activation by their cognate ligands, cytokine receptors undergo intracellular routing towards lysosomes where they are degraded. Cytokine receptor signaling does not terminate at the plasma membrane, but continues throughout the endocytotic pathway. The modes of internalization and intracellular trafficking of specific receptors, the level of recycling towards the plasma membrane, the type of protein modifications (phosphorylation, ubiquitination) and the enzymes involved in these processes are remarkably diverse. This heterogeneity may contribute to the fine-tuning of signal amplitudes and duration from different receptors. The colony-stimulating factor 3 receptor (CSF3R) is unique for its balanced signaling output, first leading to proliferation of myeloid progenitors, followed by a cell cycle arrest and granulocytic differentiation. The mechanisms associated with CSF3R signal modulation, involving receptor lysine ubiquitination and redox-controlled phosphatase activities, are to a large extent confined to the signaling endosome. Interactions between signaling endosomes and the endoplasmic reticulum play a key role in this process. Here, we review the mechanisms of intracellular routing of CSF3R, their consequences for myeloid blood cell development and their implications for myeloid diseases.
