 The IDeal Program, also known as the Innovation and Delivery Program, was created to encourage collaboration among industry, Alberta universities and research institutions. The Alberta Prion Research Institute invites applications for research and development projects undertaken by Alberta-based private sector organizations or public sector researchers and their private sector partners. A private sector partner may be a company, an industry association or similar body. Direct project costs are shared by private sector partners and the funders. IDeal grants are typically of an applied nature and directed at a specific challenge identified by the private sector partner and the industry. Themes accessible for funding are:
  • Protein folding and misfolding in prion diseases;
  • The pathobiology of TSEs;
  • Surveillance and control of prion diseases;
  • Diagnostic technologies;
  • Solutions to enhance market access;
  • Innovative disposal and/or uses of specified risk material;
  • TSEs and society;
  • Protein folding and misfolding in prion-like human neurodegenerative diseases; and
  • Prion-like mechanisms in human neurodegenerative diseases.
Funding may be up to $500,000. Projects may range from one to three years in duration.

Application Deadline: continuous intake


The Guest Speaker Support Program is designed to disseminate knowledge to the Alberta research and science community by offering funding to help bring notable researchers in prion and protein misfolding science to Alberta to present lectures and to participate in panel discussions. These experts assist with planning or implementing collaborative research programs and/or explore and evaluate recent breakthroughs in prion science. Speakers might be involved in research related activities or public studies or both. Funds are provided primarily to offset the costs of travel and accommodation for guest speakers. Support of up to $1,500 is provided for speakers travelling within North America, and up to $2,500 is provided for speakers travelling from outside North America. In some cases, the Alberta Prion Research Institute will consider application for a contribution toward the cost of conducting an associated conference, symposia or workshop.

Application Deadline: continuous intake


The Expanding Horizons Program is a professional development program for graduate students and postdoctoral fellows who are currently working on prion research. The objective of this program is to provide research trainees with access to mentoring in order to develop skills and knowledge that are applicable both within and outside of the lab. Seminars focus on career development in research as well as other careers they might undertake such as those in industry or policy making. Ensuring trainees are skilled in topics like lab management, networking, communicating, interview skills and grant crafting will benefit their futures as well as the future of prion research.

*** Effect of heating on the stability of amyloid A (AA) fibrils and the intra- and cross-species transmission of AA amyloidosis Abstract

Amyloid A (AA) amyloidosis is a protein misfolding disease characterized by extracellular deposition of AA fibrils. AA fibrils are found in several tissues from food animals with AA amyloidosis. For hygienic purposes, heating is widely used to inactivate microbes in food, but it is uncertain whether heating is sufficient to inactivate AA fibrils and prevent intra- or cross-species transmission. We examined the effect of heating (at 60 °C or 100 °C) and autoclaving (at 121 °C or 135 °C) on murine and bovine AA fibrils using Western blot analysis, transmission electron microscopy (TEM), and mouse model transmission experiments. TEM revealed that a mixture of AA fibrils and amorphous aggregates appeared after heating at 100 °C, whereas autoclaving at 135 °C produced large amorphous aggregates. AA fibrils retained antigen specificity in Western blot analysis when heated at 100 °C or autoclaved at 121 °C, but not when autoclaved at 135 °C. Transmissible pathogenicity of murine and bovine AA fibrils subjected to heating (at 60 °C or 100 °C) was significantly stimulated and resulted in amyloid deposition in mice. Autoclaving of murine AA fibrils at 121 °C or 135 °C significantly decreased amyloid deposition. Moreover, amyloid deposition in mice injected with murine AA fibrils was more severe than that in mice injected with bovine AA fibrils. Bovine AA fibrils autoclaved at 121 °C or 135 °C did not induce amyloid deposition in mice. These results suggest that AA fibrils are relatively heat stable and that similar to prions, autoclaving at 135 °C is required to destroy the pathogenicity of AA fibrils. These findings may contribute to the prevention of AA fibril transmission through food materials to different animals and especially to humans.

 why do we not want to do TSE transmission studies on chimpanzees $

5. A positive result from a chimpanzee challenged severly would likely create alarm in some circles even if the result could not be interpreted for man. I have a view that all these agents could be transmitted provided a large enough dose by appropriate routes was given and the animals kept long enough. Until the mechanisms of the species barrier are more clearly understood it might be best to retain that hypothesis.

Diagnosis and Reporting of Creutzfeldt-Jakob Disease

To the Editor: In their Research Letter, Dr Gibbons and colleagues1 reported that the annual US death rate due to Creutzfeldt-Jakob disease (CJD) has been stable since 1985. These estimates, however, are based only on reported cases, and do not include misdiagnosed or preclinical cases. It seems to me that misdiagnosis alone would drastically change these figures. An unknown number of persons with a diagnosis of Alzheimer disease in fact may have CJD, although only a small number of these patients receive the postmortem examination necessary to make this diagnosis. Furthermore, only a few states have made CJD reportable. Human and animal transmissible spongiform encephalopathies should be reportable nationwide and internationally.

Terry S. Singeltary, retired (medically) CJD WATCH

I lost my mother to hvCJD (Heidenhain Variant CJD). I would like to comment on the CDC's attempts to monitor the occurrence of emerging forms of CJD. Asante, Collinge et al [1] have reported that BSE transmission to the 129-methionine genotype can lead to an alternate phenotype that is indistinguishable from type 2 PrPSc, the commonest sporadic CJD. However, CJD and all human TSEs are not reportable nationally. CJD and all human TSEs must be made reportable in every state and internationally. I hope that the CDC does not continue to expect us to still believe that the 85%+ of all CJD cases which are sporadic are all spontaneous, without route/source. We have many TSEs in the USA in both animal and man. CWD in deer/elk is spreading rapidly and CWD does transmit to mink, ferret, cattle, and squirrel monkey by intracerebral inoculation. With the known incubation periods in other TSEs, oral transmission studies of CWD may take much longer. Every victim/family of CJD/TSEs should be asked about route and source of this agent. To prolong this will only spread the agent and needlessly expose others. In light of the findings of Asante and Collinge et al, there should be drastic measures to safeguard the medical and surgical arena from sporadic CJDs and all human TSEs. I only ponder how many sporadic CJDs in the USA are type 2 PrPSc?
