Robert Moir, Ph.D.
Assistant Professor in Neurology, Harvard Medical School
Assistant Professor in Neurology, MGH Neurology Research
Dr. Moir obtained his PhD from the University of Melbourne in the laboratory of Professor Colin Masters, one of the pioneers and founders of the modern era of Alzheimer's disease research. He joined the research unit of Professor Rudolph Tanzi at Harvard Medical School and Massachusetts General Hospital in 1994 as a Postdoctoral fellow. He is now an assistant Professor with joint appointments at HMS and MGH and runs his own research laboratory located at the MIND research facility in Charlestown MA.
Project Description Researchers Funding The Amylin Protein of Diabetes Mellitus is an Antimicrobial Peptide
The goal of this project is to determine whether the amylin (IAPP) protein has a role in innate immunity (similar to Abeta) in order to significantly advance our understanding of the origins of diabetes pathology and its possible linkage to Alzheimer’s disease.Robert Moir, Ph.D.Rudy Tanzi, Ph.D.

Potential for Host Cytotoxicity from Microbially-derived Abeta Oligomers
Alzheimer’s disease (AD) is the most common form of dementia in the elderly afflicting over 20 million people worldwide. Two decades of findings from cell biology, genetic, neuropathological, biochemical and animal studies overwhelmingly point to the β-amyloid peptide (Aβ) as the key protein in the disease’s pathology (see review by Hardy and Selkoe, 20001). Aβ appears to be a soluble component of normal brain. However, in AD brain the peptide accumulates as β-amyloid, an insoluble semi-crystalline deposit that is the hallmark of the disease pathology.Rudy Tanzi, Ph.D.Robert Moir, Ph.D.Charles Glabe, Ph.D.
Investigation of Certain Properties of Mitochondria Membranes Related to AD
While the mechanism of Aβ cytotoxicity remains contentious, evidence is accumulating that membrane permiabilization plays a key role in the pathological activity of the peptide. This study will focus on role of Aβ oligomerization in the Aβ-mediated disruption of lipid bilayers.Robert Moir, Ph.D.Rudy Tanzi, Ph.D.
Identification of Agents that Inhibit the Generation and Neurotoxicity of Cross-linked B-amyloid Protein Species
We have coined the term CAPS to describe cross-linked-Beta-amyloid protein species. CAPS, particularly dimeric forms, are highly neurotoxic. CAPS are also abundant in vivo, with dimeric species alone comprising as much as 40 percent of the total Abeta pool in late state AD brain. In this study we plan to screen compound libraries for potential therapeutic agents that attenuate the levels and/or cytotoxic activity of CAPS.Robert Moir, Ph.D.Rudy Tanzi, Ph.D.
