Overview

Immune white cells, such as cytotoxic T lymphocytes (CTL) and natural killer (NK) cells, protect us from infectious diseases and cancer by killing infected or unwanted cells. Conversely, defects in the function or regulation of these cells can lead to immunodeficiency or autoimmunity. Currently we are studying the role of these cells in two diseases: type 1 diabetes and X-linked lymphoproliferative disease. In both these disorders, we have described defects in CTL and NK cells. By identifying these defects in detail we hope that we will be able to develop novel therapies for disease.

Research

Medical microbiology, virology and infection control (clinical)
The medical microbiology laboratory in the Department of Pathology & Laboratory Medicine at BC Children's Hospital (BCCH) is a leader in the development of molecular diagnostic assays for pediatric infectious diseases. For example, molecular assays have been developed for human herpesvirus 6 (HHV-6), enteroviruses and Epstein-Barr virus, for the diagnosis and typing of Neisseria meningitidis (meningococcus) and for novel agents such as human metapneumovirus. The laboratory is continually adapting and developing new real-time (Taqman) and rapid Smart Cycler PCR diagnostics for a variety of bacterial and viral pathogens. In addition, the laboratory is engaged in changing the primary care management of common respiratory illnesses by providing a VIral RAPid testing program (VIRAP) that allows for the rapid (less than 4 hour) diagnosis of common respiratory pathogens.

Autoimmunity in type 1 diabetes
Type 1 (juvenile-onset) diabetes mellitus arises from a T-cell-mediated autoimmune process directed against pancreatic beta cells in both humans and non-obese diabetic (NOD) mice. The destruction of beta cells is mediated by CD8+ cytotoxic T lymphocytes (CTL). Using MHC Class 1 tetrameric complexes to detect and determine the frequency of autoreactive CTL in NOD mice we have developed a predictive algorithm for disease. In collaboration with Drs. Bruce Verchere and Dina Panagiotopoulos we are hoping to extend these findings to humans through the identification of human MHC class I restricted epitopes. The laboratory is also studying several different areas of the pathogenesis of type 1 diabetes including the role of autoreactive CTL and the role of natural killer cells.

X-linked lymphoproliferative disease
We have cloned and sequenced a novel mutation in the gene responsible for the fatal childhood disease, X-linked lymphoproliferative disease (XLP), thus resolving a longstanding mystery of unexplained male deaths in a large aboriginal family from northern Canada. The presence of the mutation in this extended family allows us to study the specific role of the lymphocyte cell protein, SLAM-associated protein (SAP) in human immunity to viruses and tumours. In particular, we are investigating the role of SAP in the cellular and molecular dysfunction of cytotoxic T lymphocytes and natural killer cells and the relationship between these abnormalities and the clinical phenotype of disease.
