Research Summary
Dr Abrahams' research focuses on understanding the role of innate immune Toll-like receptor and Nod-like receptor family members in placental and maternal-fetal immune responses, and their role in regulating pregnancy outcome, including those complicated by infections and by autoimmune diseases. Studies from the Abrahams laboratory characterizes the mechanisms by which Toll-like receptors, Nod-like receptors, and the inflammasome function in the placental trophoblast and fetal membranes in response to both infectious and non-infectious stimuli.
