CC Chemokines
CXC chemokines can exert direct effects on ECs, whereas CC chemokines contribute to neovascular- ization generally in indirect manners, although direct role of certain CC chemokines has also been reported.
Several CC chemokine members are thought to con- tribute to tumor angiogenic activities, including CCL2 (MCP-1), CCL5 (RANTES), CCL7 (MCP-3), CCL8
(MCP-2), CCL17 (TARC) CCL 20 (LARC/MIP-3α), CCL22 (MDC) and CCL23 (MPIF-1/MIP-3). These chemokines are produced mainly by tumor infiltrating lymphocytes, and some of them also by tumor cells.
They attract circulating mesenchymal cells...
