Development of a device for selective removal of CD4+ T cells

Development of a device for selective removal of CD4+ T cells

Therapeutic Apheresis and Dialysis 7(3): 329-333

To control antigen (Ag)-specific immune cells is important in the treatment of autoimmune diseases. In particular, controlling the immune response of autoimmune T cells is effective in the treatment of these diseases. The development of a device that can remove CD4+ T cells specifically by extracorporeal circulation is now in progress, with the aim to deplete autoimmune T cells. We developed a removal material made of polypropylene non-woven fabrics with anti human CD4 monoclonal antibody immobilized on the surface. Using a column packed with the removal material, we succeeded in removing CD4+ T cells specifically from peripheral whole blood by direct perfusion. Moreover, CD4+ T cells can be specifically removed even from blood with lower surface antigen density by in vitro activation.
