Research Summary

As a neuropathologist, I am interested in neurologic diseases in general, including memory and movement disorders, demyelinating diseases, autoimmune disorders (especially systemic lupus erythematosus), stroke, central nervous system infections, and brain tumors. Currently, my major research and clinical focus is examining cellular dysfunction and toxicity due to amyloid deposition in Alzheimer's disease and transthyretin amyloidosis.

» In collaboration with Dr. Alejandro Ivan Hernandez, we are studying how alterations in PARP1, an enzyme necessary for long-term memory, may contribute to memory impairment in Alzheimer's disease. Changes in PARP1 localization within neurons of the hippocampus appear to be associated with the presence of beta-amyloid plaque and neurofibrillary tangle pathology.

» We are studying why different forms of transthyretin (TTR) amyloid deposit in different tissues and signaling pathways by which amyloid deposition leads to tissue damage. TTR amyloidosis (ATTR), a common form of amyloidosis, is a lethal systemic disease caused by a mutation in the TTR gene. Mutations result in a misfolding of protein monomers derived from the tetrameric plasma protein TTR and subsequent fibril formation and accumulation in tissues, leading to cardiomyopathy and/ or polyneuropathy. In the elderly, wild type TTR also can give rise to amyloid, resulting in cardiomyopathy and referred to as Senile Systemic Amyloidosis (SSA). It is not known why or how deposition of the wild-type TTR and different mutations lead to different clinical phenotypes.
