CliniMACS
®
CD4 Product Line

CD4 is an accessory molecule involved in the recognition of foreign antigens in association with MHC class II antigens by T cells. T helper cells and to a lower degree monocytes and dendritic cells express CD4.
The CliniMACS® CD4 Product Line consists of murine anti-CD4 monoclonal antibodies conjugated to superparamagnetic iron dextran particles.
One vial contains 7.5 mL sterile, non-pyrogenic solution.
The performance of the CliniMACS CD4 Product Line depends on the individual separation strategy. For information on respective capacities, refer to the CliniMACS User Manual or contact your local representative.
Please inquire about required CliniMACS System components and accessories.

T cells have been used as the basis for various gene therapy approaches, for example, in the human immunodeficiency virus (HIV) setting.

In the allogeneic transplantation setting, CD4
+
T cells in donor lymphocyte infusions (DLI) may be capable of mounting GvT responses, concomitantly reducing the risk of GvHD

and reconstituting the recipient’s immune system.

Additionally, Th2 cells have been successfully used to support stem cell grafts.
8
The combined depletion of CD4
+
and CD8
+
T cells results in a cellular product enriched for cells of the innate immune system, such as TCRγ/δ T cells and subpopulations of NK cells.
9,10
The use of such donor innate lymphocyte infusions (DILI) is aiming at improving engraftment and anti-tumor effects, while at the same time reducing the risk of GvHD.
