Recently it has been shown that interferon (IFN)-γ plays an important role in mesothelioma, mediated by the main IFN-γ dependent chemokines, chemokine (C-X-C motif) ligand (CXCL)10/IFN-γ- induced protein 10 (IP-10). IP-10 is up-regulated in malignant mesothelioma (MM), suggesting a relationship with development of these tumors. Nanoparticles containing nickel, that increase the risk for pleural diseases, induced increased levels of IP-10 in rat pleural mesothelial cells. Chemokine (C-X-C motif) receptor (CXCR)3 expression in CD4(+) T cells from pleural plaques and MMs was significantly decreased compared with that from healthy donors suggesting that CXCR3, IFN-γ, and IP-10 may be candidates to detect and monitor disease status. In a patient with asbestos-related malignant pleural mesothelioma the oncolytic adenovirus (ONCOS-102) induced prominent infiltration of CD8(+) lymphocytes to tumor, marked induction of systemic antitumor CD8(+) T-cells and expression of IP-10. Furthermore, increased IP- 10 concentrations were observed in the sera of the asbestos-exposed workers and were associated with the severity of asbestos-related diseases. These findings suggest that IP-10 chemokine may have a prognostic role in the progression of asbestos-related diseases and could be used for the health surveillance of either workers with an occupational history of asbestos exposure or patients affected by nonmalignant asbestos-related diseases.
