Bio Statement

Dr. Costalonga's research interest is centered in the in the area of mucosal immunology and animal models of periodontitis. Dr. Costalonga is funded by the National Institute of Health to study the interaction of commensal and pathogenic microorganisms with the mucosal immune system of the nose and of the intestine. He has developed a mouse model of periodontitis to study the contribution of T to the disease process. Future funding will focus on the contribution of mucosal dendritic cells to the developing phenotype of antigen specific T cells. He has served on the Oral, Dental and Craniofacial Sciences Study Section at the NIH as an ad hoc member for mucosal immunology. He teaches immunology to dental students, and literature review in Periodontology as well as bacteriology and immunology to residents in periodontology. In the Graduate Periodontology Clinic floor he teaches conventional periodontics and implantology of complex cases.

Research Interests

Dr. Costalonga and his co-investigator Mark Herzberg, professor in the Department of Diagnostic and Biological Sciences, are completing a three-year R01 grant from the National Institute of Dental and Craniofacial Research to study how commensal microorganisms interact with the immune system at mucosal sites such as the intestine and the airways. Central to Costalonga's research is a mouse model of the immune system that he developed through collaboration with Marc Jenkins and Patrick Cleary, both professors in the Department of Microbiology in the Medical School. Using the adoptive transfer technique pioneered by Jenkins, Costalonga obtains and then transfers mouse T cells that specifically recognize ovalbumin (a foreign protein to mice) into normal mice. These mice are then fed a strain of the commensal bacterium Lactobacillus murinus that has been modified to express ovalbumin.

As these bacteria colonize the intestine, the transferred ovalbumin-specific T cells see the bacteria's ovalbumin tag and mount a response. Costalonga subsequently retrieves these T cells and analyzes them for two key responses: proliferation and cytokine production. The results indicate if the immune system is responding to the ovalbumin through cell-mediated immunity (by stimulating macrophages) or antibody production by B cells. He is also examining T cell responses in the nasal lymphoid tissues after administering ovalbumin- tagged L. murinus or Streptococcus pyogenes, a pathogen that can cause rheumatic fever and other serious illnesses. That work addresses a long-term goal of the research, which is to compare the responses to commensal bacteria to those induced by pathogens.

In another mouse model, Costalonga is investigating the connection between periodontitis and the immune response to bacteria. Porphyromonas gingivalis causes an inflammatory response that induces bone loss in BALB/c mice, but induces neither inflammation nor bone loss in another strain of mice, C57BL/6. He is studying a protein known as toll-like receptor 4 (TLR4) found on antigen-presenting cells (dendritic cells and macrophages, for example) that is one of the first molecules to interact with P. gingivalis. Costalonga wants to understand how the cascade of events that culminates in bone resorption is initiated by TLR4-P. gingivalis binding. Early results with TLR4-deficient mice indicate that the effects of the bacteria on bone loss can be modulated based on TLR4 expression. In time, he plans to use the adoptive transfer technique to study T and B cell responses that may contribute to bone loss in these mice.
