Expression of melanoma-associated antigens in human dendritic cells pulsed with an interleukin-2 gene encoded vaccinia melanoma oncolysate (rIL-2VMO).

Abstract

Dendritic cells (DCs) possess the unique abilities to initiate a primary immune response and to present antigens to naïve T lymphocytes. Recently, there has been a rapidly growing interest in the use of DCs in active specific immunotherapy (ASI) for the treatment of patients with cancer. In the present study, we determined the ability of DCs to express Melanoma-Associated Antigens (MAAs) from a polyvalent Melanoma Vaccine (DC-MelVac; Patent #11221/5) developed in our facility. The vaccine consists of a recombinant IL-2 gene-encoded vaccinia melanoma oncolysate (rIL-2VMO) derived from an established human melanoma cell line. Our results show that r-IL2VMO-pulsed DCs express MAAs presented by the Mel-2 melanoma cell line oncolysate used in this study. We believe that these promising results will prove useful as an active specific immunotherapeutic agent for patients with Stage III melanoma.
