Research in the Seyfried lab is focused on the integration of proteomics, systems biology, and molecular biology to tackle fundamental questions related to the pathogenesis of Alzheimer’s Disease (AD) and other neurodegenerative disorders. In particular, we utilize high resolution liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) to identify and quantify proteins and post-translational modifications (PTMs). Combining tools in both molecular and cellular biology, we also explore the relationship between the function of these proteins and their PTMs in the development of these devastating diseases.

Our funded projects are currently focused on the development of mass spectrometry-based techniques for:

(1) Systems level analysis of quantitative proteomic and transcriptomic expression in human donor postmortem brain tissue
(2) Identification and quantification of protein post-translational modifications including ubiquitination, phosphorylation, methylation and acetylation
(3) Proteomic biomarker discovery in cerebrospinal fluid (CSF), plasma and platelets in Alzheimer’s Disease and other related neurodegenerative diseases
(4) Proteogenomic applications to identify rare coding changes at the peptide level in AD candidate risk genes

In the News
