Grade 11 student James McLeod bested 12 fellow regional finalists from across Canada with a study into how the HIV/AIDS virus attacks specific cells in the body's immune system.
In addition to James McLeod of Kanata (1st prize, $5,000), the top prizes went to David Wang of London (2nd place, $4,000), Kartik Madiraju of Montreal (3rd place, $3,000) Philip Edgcumbe and Maxim Winther of Vancouver (4th place, $2,000) and Emily Cooley of Calgary (5th place, $1,000).
London's David Wang and Marzieh Ghiasi of Halifax tied for a special prize recognizing research with the greatest commercial potential.
David genetically engineered tobacco plants to produce human interleukin 13, an anti?inflammatory protein with the potential to prevent or treat juvenile diabetes. Marzieh's research revealed how certain bacteria could be used to remove arsenic from drinking water. Both won a special $1,000 honorarium.
McLeod won the $5,000 top Canadian prize after a cross-country series of student presentations via videoconference yesterday to a panel of seven distinguished scientists at the National Research Council in Ottawa.
Understanding how the HIV-AIDS virus attacks the body's immune system
Necessity may be the mother of invention but curiosity is surely a close relative. It was last year in a Grade 10 health class discussion about the HIV-AIDS virus that curiosity got the better of James McLeod.
"Our teacher was explaining how the virus attacks specific cells in the body's immune system," James, 16, recalls. "I remember thinking about that process and wondering why it happens. My teacher loaned me some university textbooks and it all just developed from there."
Now in Grade 11 at All Saints High School, Kanata, and mentored by Dr. Angela Crawley and Jonathan Angel of the Ottawa Health Research Institute, James focused his research on T-cells, important components of a healthy immune system. He wanted to know if there was a genetic explanation for the rapid death of T-cells, and the associated compromised state of the immune system, which is a hallmark of advanced stages of HIV-AIDS infection.
By examining RNA transcripts of particular T-cells, James found that a protein molecule called CD127 was preventing the delivery of a "survival signal" by a hormone called interleukin-7, which is needed for the development, survival and proliferation of T-cells.
"Now that we have a detailed picture of what is happening to the T-cells, we can look at therapies designed to prevent it," he said.
The success of the project has pushed biotechnology up a few spots on James' list of possible career choices, but he's in no hurry to decide. "I've got another year of high school and a lot of things I'm interested in," he says.
Some of the brightest young scientists in Canada
In remarks at the ceremony, NRC Vice-President Dr. Roman Szumski, who served as one of the judges, said finalists in this competition "represent some of the brightest young scientists in Canada and I congratulate them all on their outstanding achievements. The NRC is proud to be part of this program and we look forward to future competitions."
He thanked the competition sponsor and Sanofi Pasteur Limited President Mark Lievonen for helping foster an appreciation of science education.

The sanofi-aventis biotech challenge is a high-level national competition that introduces students to the real world of biotechnology by carrying out research projects of their own design.
Each of the student teams work with a mentor in their community who provides expert advice and access to equipment and supplies. Many students who compete go on to pursue careers in biotechnology, healthcare, agriculture, and the environment.
Senior officials from the federal public service and the private sector served as judges.
Speaking on behalf of the judges, Sanofi Pasteur Limited Vice-President Luis Barreto said: "The competition has presented an increasing challenge in last five years; the quality of science never stops surprising the judges. It is gratifying, however, to see that the future of biotechnology in Canada is in good hands."
National sponsors of the competition:
Each regional competition also includes cash prizes. They are supported by local companies, educational institutions, industry organizations and government agencies. More than 100 organizations are partnered in this educational outreach initiative.
The competition mirrors the real world of scientific research by:
Winning student teams share their cash prize with their school. In some cities, winning students also receive university scholarships or summer jobs.
Many of the events also include lectures by some of local community's leading biotechnology researchers, science workshops for students and teachers, and exhibits on biotechnology.
