How can I find ligands of receptors (or vice versa)?

For example, I want to find the receptors of IL-8 (CXCL8).

CellPhoneDB is a publicly available repository of curated receptors, ligands and their interactions.

The interactions can be searched or downloaded.

Have you tried STRING?

It's a publicly available protein-protein interaction database, so it won't be a complete picture.

Ingenuity Pathways Analysis (IPA) is really nice but is a paid service. Ask your institution if they have a license for one.

CellTalkDB is another option for a searchable ligand-receptor database. According to the webpage it is curated from other databases and the literature. Details are available in the publication.
