摘要:
An isolated cell having a central memory T-lymphocyte (Tcm) phenotype, the cell being tolerance-inducing cell and capable of homing to the lymph nodes following transplantation, the cell being transduced to express a cell surface receptor comprising a T cell receptor signaling module is disclosed. Methods of generating same and using same are also disclosed.

This invention relates to acellular-based therapies for decreasing the level of regulatory T cells (Treg) and/or increasing the level of pro-inflammatory T cells (Th17) to favor immune stimulation. To provide these therapeutic effects, an allogeneic leukocyte population is contacted with another leukocyte population and the acellular components produced are isolated. The leukocyte populations are contacted so as to allow pro-inflammatory allo-recognition. Acellular-based preparations and processes for achieving therapy are also provided.
摘要:
Methods are described for the isolation and selection of a heterogeneous bone marrow cell population, called NCS-01, that is effective at treating neurodegeneration. For example, NCS-01 cells are shown to treat neurodegeneration caused by ischemia. In vivo studies demonstrate that selected NCS-01 cell populations treat neurodegeneration in a standard rat middle cerebral artery occlusion (MCAO) animal model under conditions of transient or permanent total arterial occlusion. These studies also disclose that when the neurodegeneration is caused by ischemic stroke, combining the administration of a selected NCS-01 cell population with thrombolytic agents and/or mechanical methods of clot removal leads to a decrease in the volume of infarction caused by acute onset neurodegeneration. The disclosed cell therapy promises to make a significant clinical impact on patient survival after stroke.

The invention features methods for increasing or maintaining the number of functional cells of a predetermined type in a mammal (e.g., a human patient), for example, the insulin producing cells of the pancreas, liver cells, spleen cells, or bone cells, that has injured or damaged cells of the predetermined type or is deficient in cells of the predetermined type.

摘要:
A method is provided for producing a population of CD8null Tc1 and/or Tc2 lymphocytes ex vivo. The method includes stimulating a population of T cells obtained from a subject by contacting the population with an anti-CD3 monoclonal antibody and an antibody that specifically binds to a T cell costimulatory molecule in the presence of a Tc1 or Tc2 supportive environment to form a stimulated population of T cells. The stimulated population of CD8null T cells is allowed to proliferate in a Tc1 or Tc2 supportive environment. Purified populations of Tc1 and Tc2 cells are disclosed herein, as are methods for their use.
摘要:
A method of treatment using immune system suppressor cells and immune system stimulator cells comprises providing stem cells; combining the stem cells with lymphoid-derived cells to produce a co-culture; adding lipopolysaccharide and a factor selected from the group consisting of granulocyte macrophage-colony stimulating factor, macrophage colony stimulating factor, granulocyte-colony stimulating factor and mixtures thereof to the co-culture; obtaining immune system suppressor cells and immune system stimulator cells from the co-culture; and introducing and the cells into a host.
摘要:
The present invention discloses selective surfaces, wherein said selective surfaces comprise a biocompatible polymer comprising maleic anhydride molecules and an apoptosis inducing ligand bound to the maleic anhydride molecules. The invention also encompasses devices and kits comprising the selective surface and methods for its production. The selective surfaces may be used for functional selection of cell populations suitable for transplantation into human subjects.
摘要:
A method for treating cancer. The method including administering to a subject in need thereof, a combination including an effective amount of polymyxin B in combination with an effective amount of ATP, wherein the combination is effective in treating a tumor or cancer in the subject.
