  • The RBC are made from stem cells in the bone marrow and transplantation of stem cells from the bone marrow of a healthy donor to someone with sickle cell disease (SCD) can lead to significant improvements in their health. (ca.gov)
  • The goal of this project is to bring to the clinical trial of treating patients with SCD by transplanting them with their own bone marrow stem cells that have been modified in the laboratory by adding the gene for a version of human beta-globin that will act to inhibit sickling of the patient's RBC ("anti-sickling" gene). (ca.gov)
  • This approach may provide a way to improve the health of people with SCD, with advantages over clinical treatments using transplantation of bone marrow stem cells from another person. (ca.gov)
  • In the first 2 years of this project we were able to demonstrate the feasibility of this approach, i.e. that the clinical cell product, the subject's bone marrow stem cells modified with the anti-sickling gene, can be produced suitably for clinical transplantation and that enough of the anti-sickling hemoglobin is made to reverse sickling of RBC made from the gene-modified stem cells.

  • Regulatory T cells (T(regs)) manipulated ex vivo have potential as cellular therapeutics in autoimmunity and transplantation. (lu.se)
  • Although it is possible to expand naturally occurring T(regs), an attractive alternative possibility, particularly suited to solid organ and bone marrow transplantation, is the stimulation of total T cell populations with defined allogeneic antigen-presenting cells (APCs) under conditions that lead to the generation or expansion of donor-reactive, adaptive T(regs). (lu.se)
  • Without further manipulation or selection, the resultant population delayed skin allograft rejection mediated by polyclonal CD4(+) effectors or donor-reactive CD8(+) T cell receptor transgenic T cells and inhibited both effector cell proliferation and T cell priming for interferon-γ production.
