Several tumor lung cells also express CX3CL1 receptor, and exogenous stimulation with soluble CX3CL1 induces their migration through mechanisms dependent on the Focal adhesion kinase and Steroid receptor coactivator (FAK-Src) complex 14 and phosphorylation of cortactin, a protein associated with the cytoskeleton 15. Here, CX3CL1 is linked to neoplasm.
