Research Interests

Periodontitis (PD) is a chronic disease of aging or inflammaging that affects 70.1% of Americans 65 years and older. PD has been linked to increased risk of other age-related diseases with more serious mortality and morbidity profiles such as Alzheimer’s disease. Increased accumulation of senescent cells with a characteristic senescence-associated secretory phenotype (SASP) occurs with advanced age, contributing to inflammaging and the pathophysiology of age-related diseases. Our laboratory has recently identified a novel pathogenic mechanism for initiation and amplification of immune senescence and alveolar bone loss in PD via microbially-induced dendritic cell SASP exosomes. My research will focus on dissecting out the role and molecular mechanisms of age-related and microbially-induced SASP exosomes in periodontal disease. Exosomes can travel to distant sites and have been shown to cross the blood-brain barrier. Thus, my lab is interested to study the role of microbially-induced SASP exosomes associated with PD in the development of systemic diseases such as Alzheimer’s. We anticipate an important outcome of these studies to be the identification of novel diagnostic biomarkers and senolytic therapies for periodontitis and other age-related diseases to warrant a healthy aging to our population.
