Carmela Abraham, PhD

Professor of Biochemistry and Medicine

abrahamcolor1_001Dr. Carmela Abraham completed her undergraduate degree at Tel Aviv University, Israel. She earned her PhD degree in Neurobiology from Harvard University. She joined the Boston University School of Medicine’s Departments of Medicine and Biochemistry in 1989 as an Assistant Professor and has since been promoted to Professor.

Research Interests

Dr. Abraham’s research interests are focused on the etiology of Alzheimer’s disease and the role of the Amyloid Precursor Protein (APP) and Abeta peptide in the development of the disease, as well as identifying molecular mechanisms leading to normal brain aging and the pathological processes that culminate in Alzheimer’s disease and multiple sclerosis. She also studies enzymes that break down the toxic Abeta peptide as a means to therapeutically clear the brain of this peptide. Genetic and molecular studies indicate that Abeta initiates the neurodegenerative aspects of Alzheimer’s disease. Dr. Abraham has also identified genes that play crucial roles in brain dysfunction leading to cognitive decline. Specifically, Dr. Abraham is studying Klotho, a cytoprotective, anti- aging protein. She is working on identifying Klotho receptors in the brain and to define the signaling pathways by which Klotho exerts its protective effects on neurons and oligodendrocytes. She is also studying Klotho’s transcriptional regulation and has identified compounds to therapeutically exploit these protective effects.
