Project description:RATIONALE: Giving high doses of chemotherapy drugs, such as busulfan and cyclophosphamide, before a donor bone marrow transplant helps stop the growth of cancer cells. It may also stop the patient’s immune system from rejecting the donor’s stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient’s bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body’s normal cells. Giving cyclosporine, methylprednisolone, and methotrexate after transplant may stop this from happening.
PURPOSE: This clinical trial studies high-dose busulfan and high-dose cyclophosphamide followed by donor bone marrow transplant in treating patients with leukemia, myelodysplastic syndrome, multiple myeloma, or recurrent Hodgkin or Non-Hodgkin lymphoma.

Project description:This phase II trial studies how well giving fludarabine phosphate, cyclophosphamide, tacrolimus, mycophenolate mofetil and total-body irradiation together with a donor bone marrow transplant works in treating patients with high-risk hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells by stopping them from dividing or killing them. Giving cyclophosphamide after transplant may also stop the patient’s immune system from rejecting the donor’s bone marrow stem cells. The donated stem cells may replace the patient’s immune system cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body’s normal cells. Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening

Project description:This pilot clinical trial studies low-dose total body irradiation and donor peripheral blood stem cell transplant followed by donor lymphocyte infusion in treatment patients with non-Hodgkin lymphoma, chronic lymphocytic leukemia, or multiple myeloma. Giving total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When healthy stem cells from a donor are infused into the patient they may help the patient’s bone marrow make stem cells, red blood cells, white blood cells, and platelets. Once the donated stem cells begin working, the patient’s immune system may see the remaining cancer cells as not belonging in the patient’s body and destroy them. Giving an infusion of the donor’s white blood cells (donor lymphocyte infusion) may boost this effect.

Project description:Human fetal and adult hematopoietic stem cells (HSC) were obtained from fetal liver, fetal bone marrow (BM), and adult BM. These were injected into human fetal thymic implants in SCID-hu Thy/Liv mice (4-6 separate mice per HSC donor) and allowed to mature into single positive CD4+ (SP4) thymocytes over the course of 7-8 weeks. SP4 thymocytes from injected stem cells were subsequently sort-purified from thymic implants and gene expression was performed. HSC from fetal (age 18-22 gestational weeks) and adult (age: 19-43 year old) HLA-A2+ donors were obtained from different tissues. After injection into human fetal thymic implants (SCID-hu Thy/Liv HLA-A2-) the cells were allowed to mature into thymocytes and sorted on the basis of HLA-A2+ expression and CD3+CD4+ (SP4) expression. 3 separate thymic implants were analyzed for each group.

Project description:Sorted cells from bone marrow and rectal mucosa of SIV-infected rhesus macaques were analyzed for expression of factors associated with plasma cell recruitment, adhesion, or maintenance mRNA expression anaylsis was performed on 16 CD2-CD19-CD20-HLA-DR+ and 16 CD2-CD19-CD20-HLA-DR- bone marrow cells, and 7 CD2-CD19-CD20-HLA-DR+ and 3 CD2-CD19-CD20-HLA-DR- rectal cells using a custom CodeSet produced by NanoString Technologies containing 44 niche factor genes of interst, 12 cell-type specific genes, and 9 reference genes identified in Genevestigator.

Project description:Patients with acute leukemia who are unable to achieve complete remission prior to allogeneic hematopoietic stem cell transplantation (SCT) have dismal outcomes with relapse rates well in excess of 60%. Haplo-identical SCT (haplo-SCT) may allow enhanced graft-versus-leukemia (GVL) effects by virtue of HLA class I/II donor-host disparities but typically requires intensive immune-suppression with post-transplant cyclophosphamide (PT-Cy) to prevent lethal graft-versus-host disease (GVHD). Here we demonstrate in preclinical models that glucocorticoid administration from day -1 to +5 inhibits alloantigen presentation by professional recipient antigen presenting cells in the gastrointestinal tract and prevents donor T-cell priming and subsequent expansion therein. In contrast, direct glucocorticoid signaling of donor T-cells promotes chemokine and integrin signatures permissive of preferential circulation and migration into the bone marrow, promoting donor T-cell residency.
