Chondroitin sulfate proteoglycans (CSPGS) are extracellular matrix components
that contain two structural parts with distinct functions: a protein core and
glycosaminoglycan (GAG) side chains. CSPGs are known to be involved in important
cell processes like cell adhesion and growth, receptor binding, or cell
migration. It is recognized that the presence of CSPGs is critical in neuronal
growth mechanisms including axon guidance following injury of nervous system
components such as spinal cord and brain. CSPGs are upregulated in the central
nervous system after injury and participate in the inhibition of axon
regeneration mainly through their GAG side chains. Recently, it was shown that
some CSPGs members like aggrecan, versican, and neurocan were strongly involved
in brain disorders like bipolar disorder (BD), schizophrenia, and ADHD. In this
paper, we present the chemical structure-biological functions relationship of
CSPGs, both in health state and in genetic disorders, addressing methods
represented by genome-wide and crystallographic data as well as molecular
modeling and quantitative structure-activity relationship.
