Wayne State University research team developing nanodevices for use in diagnostics and therapy of numerous inflammatory and infectious diseases

DETROIT – A team of researchers from Wayne State University’s College of Engineering, School of Medicine and the Kresge Eye Institute have been collaborating to discover and develop new nanodevices that will aid in the diagnosis and treatment of a number of neuroinflammatory diseases and infections that are currently difficult to target and treat.

The team led by Rangaramanujam Kannan, Ph.D., associate professor of Chemical Engineering, with collaborators Sujatha Kannan, M.D., assistant professor of Pediatrics and Raymond Iezzi, Jr., M.D., assistant professor of Ophthalmology at the Kresge Eye Institute (Ligon Center), have received funding recently from the Ralph Wilson Medical Research Foundation to develop a therapeutic approach that will target and treat neuroinflammation in age-related macular degeneration and cerebral palsy by developing a novel drug-dendrimer-based sustained delivery nanodevice formulations, which are currently being patented by the team. The research may also have a strong impact on diseases such as Alzheimer’s, multiple sclerosis, amytrophic lateral sclerosis and Parkinson’s disease. In addition, the husband and wife Kannan team are collaborating with the Perinatology Research Branch (PRB) of the National Institute of Child Health & Human Development housed at Wayne State University and the Detroit Medical Center to establish a nanotechnology unit to develop diagnostic and therapeutic approaches to fetal inflammation with the goal of addressing an important cause of preterm birth and fetal injury. The precise goal is to develop a dendrimer-based nanodevice that will be used for the diagnosis and treatment of inflammation and infections for applications in maternal-fetal medicine.

“The PRB has established a unit to develop applications of nanotechnology in perinatal medicine under the leadership of Dr. Kannan because we are convinced that this approach will enhance early diagnosis of inflammation in utero as well as treatment,” commented Roberto Romero, M.D., chief of the Perinatology Research Branch. “Dr. Sujatha Kannan and Dr. R. Kannan have established an animal model of inflammation-induced cerebral palsy and explored potential mechanisms to prevent such injury. Application to humans requires new methods for diagnosis and drug delivery into the amniotic cavity. Such goals could be accomplished using nanotechnology and, hence, the partnership between Dr. Kannan and the Perinatology Research Branch,” Dr. Romero added.

Age-related macular degeneration (ARMD) and cerebral palsy (CP) are two major diseases that affect individuals at opposite ends of the age spectrum. ARMD is a retinal degeneration that affects more than nine million elderly individuals and CP affects millions of children. “There is an increasing body of literature, in addition to evidence from our own research relating to the disease mechanisms that suggests that neuroinflammation plays a key role in the pathogenesis and evolution of both of these diseases,” said R. Kannan. “Through funding from Mr. Wilson’s medical research foundation, we hope to develop therapeutic approaches that will target and treat neuroinflammation and lead to improved treatment outcomes,” he added.

“The novel drug discovery technologies have resulted in the development of a large number of potentially powerful drugs,” said R. Kannan. “To maximize their affect and minimize side effects are becoming increasingly critical. We believe our novel drug-carrying nanodevice will offer solutions to treat a variety of diseases that currently are difficult to treat due to lack of technology that can reach the specific target the drug needs to hit,” Kannan added.

In addition to funding from the Wilson Foundation, the Kannan team is working towards developing nanodevices that will aid in diagnosis and drug therapy for maternal infections that can spread to the fetus. “Often treatments for maternal infections can spread to the fetus,” said Gloria Heppner, Ph.D., associate vice president for Research at WSU and member of the Ralph Wilson Medical Research Foundation Scientific Advisory Committee. “Through the technology being developed by the Kannan team, there may soon be a more effective and safe treatment method for effectively treating the fetus for a variety of infections that are currently difficult to treat,” Heppner added.

“We are very pleased that Professor Kannan’s research has been recognized by the Wilson Foundation and the NICHD-PRB,” commented Charles Manke, Ph.D., chair of WSU’s Department of Chemical Engineering. “For the last several years, we have focused on developing new research programs in nanomedicine, as exemplified by Professor Kannan’s innovative research in targeted drug delivery. These awards are important milestones for his ability to innovate and forge collaborative research teams.”

“The kind of interdisciplinary research teams that are emerging at Wayne State will enable faster translation of nanotechnology to the medical field and beyond,” commented Ralph Kummler, Ph.D.,dean of Wayne State’s College of Engineering. “President Irvin Reid has been extremely committed to our nanoscience research developments through the President’s Research Enhancement Fund, and we’re beginning to see the fruits of this commitment payoff,” Kummler added.

Wayne State University is one of the nation’s pre-eminent public research universities in an urban setting. Through its multidisciplinary approach to research and education, and its ongoing collaboration with government, industry and other institutions, the university seeks to enhance economic growth and improve the quality of life in the city of Detroit, state of Michigan and throughout the world.
