摘要

The invention relates to monocytes derived antigen presenting cells (MD-APCs) characterized in that they have the following properties: they present on their surface: antigen CD14 and CD64 with a mean intensity of about 5 to about 200; antigen CD80 and CD86 with a mean intensity of about 20 to about 200; antigen CD40 and mannose receptor with a mean intensity of 50 to 500; they are substantially devoid of the surface antigens CD1a and CD1c; they present a phagocytosis property; and they have the property of stimulating the proliferation of allogenic lymphocytes.
