Research Summary
Armin Alaedini's laboratory utilizes a multidisciplinary approach that includes proteomics, immunology, biochemistry, and molecular biology to study host-microbe interactions and the role of microbial and dietary antigens in immune-mediated mechanisms affecting the gastrointestinal (GI) and nervous systems. Our research is focused on the following areas:

Research Activities
Research Area 1 – Inflammatory response to dietary and microbial antigens in the context of GI and neuropsychiatric disease—investigating the gut-immune-brain connection.
Human intestinal mucosal surfaces are colonized by large communities of microorganisms and are in constant contact with an abundance of highly immunogenic dietary and microbial components. Proper regulation of the interaction between the host and the contents of the GI tract is of utmost importance in avoiding aberrant immune responses and requires several different mechanisms. Failure of one or more of these regulatory mechanisms can adversely affect human health, not only through GI disorders, but also in the context of systemic manifestations that may influence cognition and behavior. A primary focus of our group is investigation of the gut-immune-brain connection and the role of intestinal inflammation in the context of GI and neuropsychiatric disease. Our research is currently funded by the National Institutes of Health, the Department of Defense, and the Stanley Medical Research Institute.

Research Area 2 – Mechanisms and biomarkers of post-infection persistence of inflammation and symptoms.
There is evidence that persistence of rheumatic and neurocognitive symptoms after antibiotic treatment of certain infections can be immune-mediated. A critical barrier to a better understanding of the mechanisms involved has been the lack of biomarkers to characterize disease phenotypes and analyze treatment outcome. Our laboratory is conducting studies to understand the connection between the bacterial strain genotype in specific infections, host immune response, and the persistence of inflammation and symptoms following antibiotic treatment. Our work is also aimed at establishing a panel of biomarkers for identifying affected individuals and predicting the outcome of patients with active infection in regard to their risk of developing post-treatment symptoms.
