Current Research

Active research projects in the group are focused on the challenging task of reproducibly creating nanomolar oligosaccharide based inhibitors for carbohydrate binding proteins, and the elucidation of the structural basis of unique molecular recognition of carbohydrate antigens by the immune system. Chemical synthesis and structural biology are central elements in nearly all projects.

Research funding in the form of operating and equipment grants to support these general objectives is derived from several sources, Alberta Ingenuity, the Natural Science and Engineering Research Council (NSERC), the Canadian Institutes of Health Research (CIHR), the Alberta Heritage Foundation for Medical Research (AHFMR)and the Canadian Bacterial Diseases Network Centre of Excellence (CBDN). Graduate students and postdoctoral fellows also hold competitive fellowships with some of these granting agencies.

The titles of currently funded grants include:

• "Carbohydrate Chemistry, Biochemistry and Immunochemistry of Microbial and Mammalian Antigens and Inhibitors."
  
• "Targeted Cancer Vaccines: Synthesis and Evaluation of Clustered Melanoma Antigens."
  
• "Synthetic oligosaccharides and neutralization of ganglioside antibodies"
  
• "Candida albicans Conjugate Vaccines: Evaluation of synthetic beta-mannan oligosaccharides conjugated to immunogenic carriers in rabbit and mouse models of experimental candidiasis."
  
• "Design and Synthesis of Drugs to Treat Alzheimer Disease by Reduction of Serum Amyloid Protein and Amyloid Deposits."
  
• "Biosensors, Multivalent Therapeutics and Vaccine Adjuvants."
  

Group facilities and special equipment

The group is well equipped to carry out synthetic and biological aspects of research on complex carbohydrates. In addition to the standard items for performing organic chemistry, other equipment includes preparative HPLC for organic and protein samples, titration microcalorimeter, UV and visible ELISA plate readers and washers, centrifuges, ultrafiltration devices and spectrophotometers. We maintain a dedicated tissue culture facility with the capability to grow mammalian cells in stationary flasks, roller bottles, shaker flasks and bioreactors. In addition to a full complement of PC to support routine work in the group, we operate 3 SGI Octane and Indigo graphics workstations.
