Abstract:
NK cell function is regulated by Killer-cell Immunoglobulin-like Receptors (KIR) some of which recognise class I Major Histocompatibility Complex molecules. KIRs have been shown to exhibit a high degree of functional diversity which is generated at several levels. However, the functional relevance of this diversity remains largely unknown. This thesis describes our approach towards elucidating the functional relevance of KIR diversity. To study this we first compiled all known KIR sequences into a database. We developed bioinformatics tools to facilitate the study of these sequences and have m

[Truncated abstract] Natural killer (NK) cell alloreactivity can be exploited in haploidentical haematopoietic stem cell transplantation (HSCT) to improve graft survival, reduce graft versus host disease and decrease leukaemic relapse. NK cells lyse cells that have reduced expression of class I HLA molecules. In an allogeneic setting, donor NK cells may be activated by the absence of donor (self) class I HLA molecules on recipient cells; the absence of self-epitopes being detected by inhibitory KIR receptors on donor NK cells.

In Canada, and more specifically in Canadian-born Aboriginals and foreign born populations, high incidence of tuberculosis (TB) causes significant morbidity and mortality. The presence or absence of specific killer immunoglobulin-like receptor (KIR) genes, individually or in conjunction, may be associated with tuberculosis (active, latent, or uninfected disease status) as well as ethnicity of an individual. It is hypothesized that the differences in KIR profiles, gene frequencies, and/or haplotypes in Canadian-born Aboriginal, Canadian-born non-Aboriginal, and foreign born individuals elicits

Abstract:
Natural killer cells (NK) cells are marrow-derived cytotoxic lymphocytes, representing 5-18% of human blood mononuclear cells. NK cells are an important component of the innate immune system in humans playing important roles in both the elimination and control of tumour metastases and leukaemia. NK activity against target cells is determined, by the net balance of the transmitted intracellular signals from both activating (pro-cytotoxic) and inhibitory (anti-cytotoxicity) cell surface receptors. One major class of such receptor is the Killer immunoglobulin-like receptors (KIRs), which were inv

Abstract:
Clinical application of natural killer (NK) cells against leukemia is an area of intense investigation. In human leukocyte antigen-mismatched allogeneic hematopoietic stem cell transplantations (HSCT), alloreactive NK cells exert powerful anti-leukemic activity in preventing relapse in the absence of graft-versus-host disease, particularly in acute myeloid leukemia patients. Adoptive transfer of donor NK cells post-HSCT or in non-transplant scenarios may be superior to the currently widely used unmanipulated donor lymphocyte infusion. This concept could be further improved through transfusion
