Arming NK cells with enhanced antitumor activity

Arming NK cells with enhanced antitumor activity

Natural killer (NK) cells hold great promise for adoptive cancer immunotherapy. The antitumor activity of NK cells can be enhanced by the transgene driven expression of chimeric antigen receptors that facilitate the selective recognition and killing of malignant cells. Recent data from our laboratory suggest that NK cells may similarly be "armed" against neoplastic cells by the expression of ca...

Arming antitumor T cells

The immune system can only prevent cancer if it recognizes and destroys precancerous cells. Antigenic targets of such an early immune response, however, have been elusive. Spisek et al. (page 831) now find that an embryonic stem cell marker is a bull's eye for immune cells in patients who have precancerous lesions but never develop multiple myeloma. Multiple myeloma is an incurable cancer that ...

Enhanced antitumor activity of epirubicin combined with cerulenin in osteosarcoma.

Osteosarcoma (OS) is the most common primary malignant neoplasm in children and adolescents. Epirubicin is one of the chemotherapeutic agents currently used for the treatment of OS; however, the efficacy of chemotherapy is hampered by the acquired drug resistance of OS. Cerulenin, an inhibitor of fatty acid synthase, has been defined as a candidate tumor suppressor. In this study, we explored t...

Interleukin-37 Mediates the Antitumor Activity in Hepatocellular Carcinoma: Role for CD57+ NK Cells

The biological role of interleukin-37 (IL-37) in cancer is large unknown. Through immunohistochemical detection using 163 primary hepatocellular carcinoma (HCC) clinical specimens, we found the expression of IL-37 was decreased in tumor tissues, and the expression level was negatively correlated with tumor size. High expression of IL-37 in HCC tumor tissues was associated with better overall su...
