CX3CR1 and ovarian carcinoma: We have found that the peritoneal mesothelial cells express the membrane-bound form of CX3CL1, and ovarian carcinoma cell adhesion to the mesothelial monolayer was significantly impaired in the presence of the CX3CL1-specific function blocking antibodies as well as upon downregulation of CX3CR1 in ovarian cancer cells using siRNA [54].
