We investigate the association of Mycobacterium avium subspecies paratuberculosis (MAP) with Crohn’s disease and Type I Diabetes based on molecular mimicry
The overall objective of our research program is to investigate the role of Mycobacterium avium subsp. paratuberculosis (MAP) in the etiology of Crohn’s disease and Type I Diabetes.
- Diagnosis: we developed nested PCR assay and have identified biomarkers to predict the presence of MAP in clinical samples.
- Pathogenesis: We are investigating MAP role in Crohn’s and Type I Diabetes in association with single nucleotide polymorphisms (SNPs) in disease-specific genes.
- Treatment: Our lab is the focal point in an international phase III clinical trial to treat Crohn’s patients with anti-MAP therapy.
- Funding: Our research program is currently funded from various sources.
