Abstract: The present invention provides a system for enhancing clearance or destruction of undesirable cells or noncellular molecular entities by tagging such cells or noncellular molecular entities with a marker that targets the cells or noncellular molecular entities for phagocytosis (phagocytic marker). The target cells can be, for example, endothelial cells, tumor cells, leukocytes, or virus-infected cells. In certain embodiments of the invention the tagging is accomplished by administering a composition comprising an antibody or ligand linked to the phagcytotic marker, wherein the antibody or ligand binds to a cell type specific marker present on or in the cell surface of a target cell. In preferred embodiments of the invention, the phagocytic marker comprises phosphatidylserine or a group derived from phosphatidylserine, thrombospondin-1, annexin I, or a derivative of any of these.
