Summary
Hematopoietic stem cell transplantation (SCT) is the only curative therapy for most blood cancers. The curative property of SCT relates to the graft-versus-leukaemia effect, which eradicates any remaining cancer after SCT. Unfortunately the success of SCT is significantly limited by three procedural complications: GVHD, graft failure, and infection. Our research aims to improve our understanding how these complications arise to develop new therapies that can be translated to clinical practice.

Summary
Most people with relapsed leukaemia and lymphoma after bone marrow transplant die of their disease. Inserting special genes into immune cells can enable them to kill leukaemia and lymphoma and has led to dramatic cures, but there is little experience in bone marrow transplant patients. We will make leukaemia and lymphoma specific immune cells from normal bone marrow transplant donors, then administer the immune cells to transplant patients to assess their safety and effectiveness.

Summary
Acute myeloid leukaemia has a poor prognosis in patients unable to undergo bone marrow transplant, in particular in the elderly. No proven therapy improves their poor outcome. There is an urgent need to identify clinically applicable, non-toxic therapies for this group of patients. We will perform a clinical trial of "microtransplantation" using unrelated stem cell donors in combination with chemotherapy to try to reduce the relapse rate in these patients without the toxic effects of standard st ....Acute myeloid leukaemia has a poor prognosis in patients unable to undergo bone marrow transplant, in particular in the elderly.

Summary
One of the most serious complications of bone marrow transplantation is veno-occlusive disease (VOD), also termed sinusoidal obstruction syndrome (SOS). This condition occurs in 10% of transplanted patients and is characterised by abnormalities of liver function, enlargement of the liver, clotting abnormalities, fluid retention and finally failure of multiple organs and death in 30-50% of cases. The cause of VOD is unknown, and its occurrence cannot be predicted in individual patients.

This condition occurs in 10% of transplanted patients and is characterised by abnormalities of liver function, enlargement of the liver, clotting abnormalities, fluid retention and finally failure of multiple organs and death in 30-50% of cases. The cause of VOD is unknown, and its occurrence cannot be predicted in individual patients. Eight families have been described in whom a number of individuals have succumbed to a condition which is clinically and histologically indistinguishable from VOD. Affected individuals also have a form of immunodeficiency (hence termed VODI), and the abnormalities are inherited in an autosomal recessive pattern. All eight are of Lebanese origin, suggesting that a single genetic ancestral mutation was responsible for the disorder in all families, who are distantly related. We have access to genetic material from three of these families, and are on the way to identifying the causative genetic abnormality. We hypothesise that understanding this abnormality will lead to an understanding of VOD which occurs after bone marrow transplantation. We have used 800 polymorphic genetic markers scattered throughout the genome to identify the location of the genetic abnormality, and have localised the defect to a region of chromosome 2 which contains approximately 37 known and predicted genes. We now aim to determine which of the gene(s) in the candidate region is responsible for VODI, and plan to examine DNA from individuals who have had VOD after transplantation to determine if they have a related abnormality. Finding the VODI gene will benefit these families through the availability of carrier detection and may also lead to an understanding of the veno-occlusive disease that occurs after bone marrow transplantation.Read moreRead less
