Anaphylatoxin C5a receptor (C5aR) was expressed in cancer cellsfrom all organs examined and at various rates in organs. Several cancer cell lines alsoexpressed C5aR. C5a augmented C5aR-expressing cancer cell invasion in a MMP-6 dependentmanner in Matrigel chambers and in implanted nude mouse skin. C5a also enhanced cancercell lung metastasis in a C5aR-dependent manner. By cell membrane-bound furin-like serineprotease cancer cells generated C5a from C5, even it in plasma, augmenting theirinvasiveness. These C5a effects on cancer cells were inhibited by antibodies againsteither C5a or C5aR, and by a C5aR antagonist. These results indicate presence of a cancercell autoactivation pathway via C5a generation and suggest availability of a new cancertherapy targeting the C5a-C5aR axis or the cancer protease.
