Glycomics and proteomics of brain diseases

The matrisome consists of an organized network of glycoproteins and proteoglycans, the structures of which are regulated spatially and temporally during both normal physiology and disease processes. At present there is very little information concerning the mature structures of matrisome molecules and how these become altered during neuropsychiatric and neurodegenerative diseases. We are building a tool set for studying matrisome molecules in aging, schizophrenia, drug abuse, Parkinson’s disease, and Alzheimer’s disease.
