about output exact ligand-receptor data of cellchat data

[tn00992786]

Dear author,

May I realize how to output exact ligand-receptor list of specific data of pathway? For example, wnt signaling pathway including different ligands participating in signaling transduction, ctgf, dkk2, igfbp4, etc, and receptor of wnt signalling pathway including fzd2, fzd7, lgr5 and lrp6.
Thanks for kind attention.

Hi @tn00992786 , all the database information is available at CellChatDB.mouse or CellChatDB.human. CellChat provides a function to extract the L-R pairs of particular signaling pathway via pairLR <- searchPair(signaling = "WNT", pairLR.use = CellChatDB$interaction, key = "pathway_name", matching.exact = T, pair.only = F).
