Dr. Kenneth Bost’s research interests center around immune response, interaction of the nervous & immune systems, and the mechanisms of mucous membrane immunity.
Dr. Bost’s research can be divided into several areas.
1) Teenagers and young adults are the age group most likely to abuse a growing list of compounds known as “club drugs”. Ecstasy, or 3,4 methylenedioxymethamphetamine (MDMA), is currently one of the most popular club drugs of abuse, and we are just beginning to learn about the deleterious effects this drug can have on central nervous system function of these young adults. While we suspect there is a link between some diseases and club drug abuse, there have been no studies to investigate whether Ecstasy might have such a deleterious effect on immune function within the central nervous system or in the periphery during microbial diseases. These studies will define mechanisms by which the club drug, Ecstasy, can modulate inflammatory responses following infection, and represent the first effort to link the use of Ecstasy with exacerbated diseases of young adults.
2) A certain herpes virus causes a mononucleosis-like illness in infected rodents which mimics very closely the disease seen in humans. Since this model has only recently been described, we know very little about the immune response against this virus. The overall goal of this research is to define the host response against this virus and to investigate how this model of herpes virus infections might augment other disease states.
3) In collaboration with Dr. Piller, our laboratories are demonstrating the feasibility of expressing vaccines and other compounds in soybeans. If successful, this work will demonstrate the feasibility of an efficient expression system for production of large quantities of vaccines, etc which are cost-effective to produce, safe to administer, and can be shipped worldwide in a highly stable form (i.e. soybeans). The fact that extensive procedures for processing soybeans into human consumables already exist suggest that this work could be readily translated to the production of soybean-derived formulations useful for treating humans or animals.
Dr. Carol Cheatham researches nutrition individuality and its effect on the development of cognitive and social behaviors.
Dr. Cheatham’s research focuses on the influences of nutrition on cognitive and social development. To explore questions of individual differences in development, she employs both behavioral (e.g., imitation & looking paradigms) and electrophysiological (i.e., ERP) methodology. Most recently, she has been asking if an omega-3 fatty acid known as DHA (docosahexaenoic acid) has an effect on declarative memory abilities. Her research program at the NRI will be a continuation of this research, but will encompass other nutrients that function within the hippocampus, a certain part of the brain, (i.e., choline, iron, and zinc). At the NRI, Dr. Cheatham will also explore, broadly speaking, the relation between an individual’s gene sequence and the utilization of nutrients and how this utilization manifests in individual differences in cognitive and social development.
Dr. Roz Coleman’s research interests involve fat metabolism in order to try to treat disorders including obesity, diabetes and heart disease.
Dr. Coleman studies fat metabolism, particularly triacylglycerol, fatty constituent, biosynthesis and its critical regulated pathways in liver and fat cells. Her laboratory is particularly interested in understanding the controls on triacylglycerol synthesis and acyl-CoA, an enzyme involved in fat metabolism, partitioning. Using enzyme derivatives, mice and cell culture models, members of her lab are identifying the regulatory control of enzymes that commit acyl-CoA to either beta-oxidation, break down of fatty acids for further uses, or to storage as complex fats. These studies will enable us to understand and treat disorders that involve disturbed fat metabolism, including obesity, diabetes and heart disease. Her recently published studies of mice have provided strong evidence that insulin resistance is caused by intermediates that impair insulin signaling. Her areas of pediatric expertise include inborn errors of carbohydrate and fat metabolism and abnormally high levels of fat in the blood.

Dr. Deborah Muoio investigates the mechanisms of metabolic regulation in skeletal muscle, specifically involving the link between overnutrition and inactivity with insulin resistance.
Dr. Muoio is an Associate Professor in the Sarah. W. Stedman Nutrition and Metabolism Center, with appointments in the Departments of Medicine and Pharmacology & Cancer Biology. Her laboratory investigates mechanisms of metabolic regulation in skeletal muscle, with emphasis on molecular events that link overnutrition and inactivity to the development of insulin resistance.

They are collaborating in a number of epidemiology studies that examine the relationship between diet, these gene SNPs, and risk for disease. After identifying a SNP of interest in humans, they make a mouse model.
