Does the purinergic system affect extracellular matrix functions in the central nervous system?
Vol 32, Issue 6, 2018
Abstract
Exracellular matrix (ECM) consists of a plethora of proteins and polysaccharides, which aggregate into an organized network connected to the surface of the producing cells. It is structurally and functionally present in all components of tissues and organs and represents the substrate on which cells adhere, migrate, proliferate and differentiate, influencing their survival, shape and function. In response to acute (trauma) or chronic (degenerative) insults, brain ECM modifies its composition and function, actively contributing to "scar forming" gliosis or tissue degeneration/remodelling. Moreover, morphological changes in dendritic spines associated with extracellular matrix remodeling play key roles in rewiring synaptic circuitry pertinent to memory formation. In the present report, we collected the main acquisitions on the functional interplay between ECM alterations and the adenine-/guaninebased purine system with particular regard on how purine compounds and their respective receptors may affect and be affected by changes of the cerebral ECM.
