Research Interests:

Our laboratory studies the interactions of microbial pathogens with the respiratory and gastrointestinal mucosal surfaces. Two model systems are currently being explored: (1) expression, structure, and function of MUC1 mucin, and (2) intestinal immunity against coccidiosis.

Expression, structure, and function of MUC1 mucin by respiratory and gastric epithelial cells. Mucin-1 (MUC1) belongs to a family of mucin glycoproteins that are divided into secreted and membrane-bound forms. MUC1 is a membrane mucin expressed by mucosal epithelial cells, and overexpressed by most carcinomas. Unlike other membrane mucins, the cytoplasmic region of MUC1 contains multiple sites of serine and tyrosine phosphorylation that are associated with a wide array of cellular processes, including the host response to pathogenic microorganisms, cell growth, cell differentiation, intercellular adhesion, and apoptosis. In collaboration with scientists at Temple University School of Medicine and the University of Maryland School of Medicine, we are currently investigating the role of MUC1 in: (1) Pseudomonas aeruginosa lung infection, (2) Helicobacter pylori gastric infection, (3) intracellular signal transduction, and (4) epithelial injury, repair, and restitution. Through these studies, we hope to glean new information relevant to understanding the pathogenesis of lung diseases such as cystic fibrosis and gastric disorders such as peptic ulcer disease and stomach cancer.

Intestinal immunity against coccidiosis. Coccidiosis is an intestinal disease caused by Eimeria spp. that impairs the feed utilization and growth of commercial poultry. Anti-coccidial antibiotics are currently used to control outbreaks of infection, but parasite drug resistance and regulatory restrictions on antibiotic use in livestock have spawned an interest in alternative strategies for disease control. In collaboration with scientists at the USDA, our laboratories are identifying immunogenic components of Eimeria with the goal of developing coccidiosis vaccines. In addition, we are isolating and characterizing cytokines and chemokines as vaccine adjuvants.

A third project in our laboratory is investigating the role of human endogenous retroviruses (HERVs) in the pathogenesis of acute onset schizophrenia and bipolar disease in collaboration with Dr. Robert H. Yolken, Johns Hopkins University School of Medicine. We have discovered that antibodies to exogenous simian retroviruses are present at significantly greater frequency in patients with schizophrenia or bipolar disorder compared with matched controls. We hypothesize that these antibodies are generated against endogenous retroviruses and can be detected by cross-reaction with exogenous viruses.
