Molecular and Immunological Aspects of Viral Infections
As a public university, 澳门六合彩官网直播 prides itself on providing solid undergraduate and graduate-level programs while being able to provide researchers the opportunity to develop ideas into reality. Dr. Karim Essani of the Department of Biological Sciences specializes in the study of molecular and immunological aspects of viral infections. Essani has been a member of 澳门六合彩官网直播 for the last 15 years and has contributed 25 original publications to the scientific community. He is one of a handful of researchers at 澳门六合彩官网直播 who have had the opportunity to conduct original work and see their projects develop into commercialized products. Using the tanopox virus as a model for his research, Essani looks at the molecular mechanisms within the viral model that dictate which gene sequences are expressed or kept silent.
Similar to the human genome, viruses are used by Essani and many top research universities because of similarities and the ability to manipulate the genome. Applying all of the data and knowledge gained from his research, Essani has focused on how different viruses can harm or benefit the human immune system. Viruses have evolved with time and have developed defense systems that can counteract the reactions of the host cell. When the tanopox virus enters a cell, it is able to reprogram the cell and dictate new processes to be performed.
Once tanopox virus has entered the cell, a new protein is produced which is then secreted into the blood stream. It may be this protein that could eliminate the need for having open heart surgery to free clogged arteries. One could simply be injected with the viral protein that would essentially serve as Drano for the body鈥檚 arteries. Viron Therapeutics has been developing one of the viral proteins discovered by Essani, conducting clinical trials on it for FDA approval as a therapeutic. The results so far are very encouraging. If such a revolutionary treatment reaches the market, it will require the collaboration of the researchers, 澳门六合彩官网直播, and a corporation that sees the potential in making a new product that will meet a market need. 澳门六合彩官网直播 and Essani have collaborated with Viron to file a patent on the viral gene sequence and novel protein, entitled 鈥淣ucleic Acid Molecules and Polypeptides for Immune Modulation,鈥 U.S. patent No. 6894155. Viron and 澳门六合彩官网直播 also entered into an agreement whereby Viron obtained commercial use rights for the patented technology and 澳门六合彩官网直播 obtained the right to receive future royalties from Viron.
Colorectal cancer is the second-most common cancer in women and the third-most common cancer in men, worldwide. For patients with advanced stage colorectal cancer, the five-year survival rate is less than 20 percent. Cancer cells have the ability hide from the body鈥檚 immune system, allowing the cancer to grow instead of being eliminated. Another avenue of research conducted in Essani鈥檚 laboratory has been to create a recombinant tanapox virus that can mobilize the body鈥檚 immune system to fight cancers. The recombinant tanapox virus specifically infects cancer cells and tags the cancer cells with a marker that directs the body鈥檚 immune system to attack these cells. Animal studies have shown that this recombinant virus significantly shrinks colorectal cancer tumors. 澳门六合彩官网直播 has recently filed worldwide patent application for this oncolytic virus technology.
All of this research will progress until somewhere in the future doctors will hopefully write prescriptions for a new, useful medical treatment based on Essani's work.
