INTRODUCTION OF DENDRITIC CELLS SUBJECT TO PARTIAL MATURATION IN VITRO TO TREAT TUMORS

摘要

The present invention provides populations of cells comprising partially matured dendritic cells that can be used for administration individuals having a tumor Partially matured dendritic cells, those contacted with a dendritic cell maturation agent for about 1 to about 10 hours, or more, efficiently take up and process tumor antigens in the area of the tumor site, complete maturation, and can subsequently migrate to the lymph nodes of a treated individual Once in the lymph node the now fully mature antigen presenting dendritic cells secrete the appropriate cytokines (eg, TNF± and IL-12) and contact T cells inducing a substantial anti-tumor immune response.
