Dr. Ghahary works on the biology of wound healing, including burns and other non-healing wounds. He is researching a biological skin substitute for burn patients and ways to treat scarring. He is also working to develop a liquid skin material for use on non-healing wounds. Such a material would provide a scaffold for the patient’s skin to close and begin to heal the wound. Currently his research is directed toward finding new strategies to deal with the non-healing pressure ulcers which are often seen in people with SCI.
Dr. Ghahary is a Professor in the Department of Surgery and Division of Plastic Surgery at the University of British Columbia. He also holds a joint appointment as an Associate Member of Dermatology and Skin Sciences at UBC. He is a Principal Investigator at ICORD, Director of the BC Professional Fire Fighters’ Burn and Wound Healing Research Group, and a member of the active staff at Vancouver General Hospital. Dr. Ghahary attended the University of Ahwaz for his B.Sc. and the University of Tehran for his M.Sc. in public health. He completed both his Ph.D. and his Post-Doctoral Fellowship at the University of Manitoba.
Dr. Ghahary’s work will soon make it from bench to bedside: the results of his research will soon be used to treat patients directly. He has already developed a cream which decreases scarring for burn patients and those recovering from surgery. Another focus of his research is type I diabetes; he has shown that blood sugar levels can be controlled by transplanting insulin-producing cells into a diabetic patient’s kidney, eliminating the need for insulin injections. The molecule IDO, utilized in this treatment as an immunosuppressant to protect these transplanted cells, could also lead to the development of a non-rejectable skin substitute.
For Dr. Ghahary, “being part of the Blusson Spinal Cord Centre is a huge advantage; it has all the tools and equipment a group needs to pursue research, but most importantly it allows collaborations and excellent administration.” With so much connection among the labs, everyone has the opportunity to learn.
The goal of Dr. Ghahary’s work is to help patients survive a terrible injury. According to Dr. Ghahary, he spends more time coming up with solutions for type I diabetes or wound healing than thinking about his own children. “Science is all the time, not just nine to five!”
Dr. Ghahary works with Dr. Andrei Krassioukov on whether skin cells below the site of an SCI behave differently than skin cells from above the injury. In particular, they examine ischemia and the levels of growth factors in the body, and how these may contribute to non-healing wounds.
With Dr. Wolfram Tetzlaff, Dr. Ghahary is examining the use of the IDO molecule to protect spinal cord transplant cells.
Islet transplantation involves moving clusters of cells from the pancreas of a donor into another person. It is a treatment for type I diabetes because the transplanted cells begin to produce insulin to regulate blood sugar levels. However, in these transplants — and transplants of skin cells to treat wounds — the transplanted cells may be attacked by the recipient’s immune system. Dr. Ghahary has identified a molecule called IDO which suppresses a patient’s immune system during skin and islet transplantation. This molecule can be used for burn patients and in diabetic transplants to help protect the transplanted cells.
Dr. Ghahary has also been involved in identifying a small molecule called FS1/FS2 which has anti-scarring effects. The molecule has been patented and has a bright future in treating scar formation both in burn and SCI patients.
