Research Interests

Abdominal aortic aneurysm

Research Description

The overall objective of this proposal is to determine if myeloid-specific Notch1 deficiency prevents or reverses AAA progression. My central hypothesis is that deficiency of Notch1 promotes differentiation of Mφ towards a M2-phenotype by a TGF-β2 dependent mechanism(s), which attenuates the inflammatory response and protects against AAA development. Successful completion of this project will provide insight into the cellular and molecular mechanisms by which loss of Notch1 signaling in macrophages prevents the progression of AAA, and ultimately may provide the basis for novel therapeutic approaches based on M2 differentiation of Mφ to treat AAA in humans.
