| abstract |
The present invention relates to an immuno- therapeutic and prophylactic vaccine comprising monocytes or immature myeloid cells (IMCs) loaded with the ligand of natural killer T cell and an antigen for the prevention and treatment of infectious disease or cancer, more precisely, an immuno-therapeutic and prophylactic vaccine comprising monocytes or IMCs loaded with α-galactosylceramide (αGalCer), a kind of glycolipid and a natural killer T cell ligand, and antigen. Monocytes or immature myeloid cells (IMCs) therein, which are easily obtainable, unlike dendritic cells, not only induce a significant level of cytotoxic T lymphocyte responses but also have a prophylactic and therapeutic effect on malignant tumor. Therefore, the immuno-therapeutic and prophylactic vaccine of the present invention can be effectively used as an immunotherapeutic agent. |
