  • Patent number: 7727523
    Abstract: Methods are provided for suppressing the immune system response in recipients of transplanted organs, tissues or cells. An extracorporeal quantity of blood from the intended transplant recipient is treated to induce monocytes contained in the blood to differentiate and form dendritic cells. The maturation of the dendritic cells is truncated at a stage where the dendritic cells can inactivate T cell clones which would otherwise generate an undesired immune system response. The immature dendritic cells can be directly administered to the transplant recipient, or the dendritic cells can be co-incubated with the bone marrow or stem cell preparation, prior to transplantation, in order to suppress or eliminate anti-recipient donor T cells contaminating the bone marrow or stem cell preparation. The methods can be used to suppress graft versus host disease in recipients of transplanted bone marrow or stem cells, or to suppress rejection of transplanted organs or tissue.

  • Patent number: 7662930
    Abstract: Various embodiments of the present invention are directed to multi-step systems and methods for target-molecule purification that employ column-chromatography-based and/or membrane-filtration-based polishing steps. In one described embodiment of the present invention, a target-protein-containing eluate having a high residual salt concentration is collected from a first chromatography column prepared with an affinity-chromatography resin, loaded onto a second chromatography column prepared with a cation-exchange resin, and eluted from the second cation-exchange column using a buffer in which a time-dependent pH gradient is established. In another described embodiment of the present invention, a partially purified target-protein-containing eluate is collected from a chromatography column and further purified by passing the target-protein-containing eluate through a salt-tolerant anion exchanger.

  • Patent number: 7625557
    Abstract: Transimmunization methods incorporating skin immunologic challenges are described for either selectively suppressing the immune response of recipients of transplanted tissue or cells or monitoring induced anti-cancer immunity. In one embodiment, skin from the transplant donor is allografted to the transplant recipient to induce an immunological response to the transplanted skin. A quantity of blood is taken from the recipient and treated to render the T cells in the blood apoptotic and to induce differentiation of blood monocytes into dendritic cells. The treated blood is incubated and administered to the recipient to induce formation of suppressor T cell clones which reduce the number of T cells attacking the transplanted tissue or organ. This tolerogenic approach can be complemented by also feeding the immature dendritic cells apoptotic or necrotic cells from the organ donor.
