CSF-1R transport and display at the cell surface have not been studied in depth.
A novel function for EHD1 in anterograde trafficking of CSF-1R was discovered.
EHD1 was found to be essential for CSF-1R presentation on the macrophage cell surface.
Targeting of CSF-1R presentation to the cell surface may improve diseases in which CSF-1R signalling is aberrant.
