Niki Moutsopoulos

Niki M. Moutsopoulos is a Greek periodontist and immunologist. She is a senior investigator in the oral immunity and infection section at the National Institute of Dental and Craniofacial Research. Moutsopoulos specializes in oral immunology and periodontitis. Her research program focuses on host-microbial interactions that can drive chronic inflammatory responses and tissue destruction in the oral cavity.

Education Moutsopoulos received a DDS degree from the Aristotle University of Thessaloniki in 1998. In 2003, she completed a certificate in periodontics at the University of Maryland School of Dentistry where she completed a PhD in immunology in 2006 in the department of diagnostic sciences and pathology. Her dissertation was titled Dissection of factors contributing to HIV susceptibility in mucosal associated lymphoid tissues. She completed graduate research in the laboratory of her doctoral advisor Sharon Wahl at the National Institute of Dental and Craniofacial Research (NIDCR). She was a research fellow at NIDCR from 2006 to 2008. Her doctorate and post doctorate work focused on immune-mediated pathologies that present in the oral cavity including Sjögren syndrome, periodontal disease and chronic wound healing. While these are distinct disease entities, they share as a salient feature non-resolving inflammation and immune mediated tissue destruction of which the mechanisms have been in the center of her research interest. Activation of chronic inflammatory pathways in various disease entities have been linked to genetic susceptibility of the host, though emerging evidence implicates microbial factors for the initiation of disease pathogenesis for the majority of chronic inflammatory and autoimmune pathologies.

Moutsopoulos's program focuses on host-microbial interactions that can drive chronic inflammatory responses and tissue destruction in the oral cavity. In her laboratory host-microbial interactions are interrogated through the use of in vitro culture systems and animal models, but her primary focus is on the study of immune-microbial interactions in humans. For this her laboratory is interrogating the oral microbiome and immune responses in the oral cavity in patient populations with oral inflammatory conditions. Moutosopoulos researches oral-barrier immunity. Her studies implement a bench to bedside approach and aim to understand the molecular and cellular basis of oral immunity in health, and in the common inflammatory disease of periodontitis. Understanding the mechanisms that microbial triggers and host elements use to regulate oral immunity in health and disease is the focus of her research program.
