Chondroitin Sulfate Induces Depression of Synaptic Transmission and Modulation of Neuronal Plasticity in Rat Hippocampal Slices

Abstract: It is currently known that in CNS the extracellular matrix is involved in synaptic stabilization and limitation of synaptic plasticity. However, it has been reported that the treatment with chondroitinase following injury allows the formation of new synapses and increased plasticity and functional recovery. So, we hypothesize that some components of extracellular matrix may modulate synaptic transmission. To test this hypothesis we evaluated the effects of chondroitin sulphate (CS) on excitatory synaptic trans… Show more

“…Hypothalamic synaptic plasticity in depression can be caused by increased mRNA expression of synaptotagmin I and synapsin I, and the latter may contribute to depression-like behaviors and HPA axis hyperactivity [ 119 ]. In addition, the extracellular matrix may be involved in synaptic stabilization and transmission and may modulate synaptic plasticity in the central nervous system [ 120 ]. In recent studies, modeling of bidirectional modulations in synaptic plasticity, designed to reveal the mechanism of long-term potentiation and long-term depression, suggested that Ca 2+ /calmodulin (CaM) pool size played a critical role in coordinating LTP/LTD expression [ 121 ].…”

“…The action of CS-BIOACTIVE© was associated with a decrease in the activity of MMP1 and MMP3 [64], and with reduced levels of biomarkers of inflammation (soluble collagen type 2, Coll2-1) in blood serum [65]. In addition, the use of CS-BIOACTIVE© is promising to treat various inflammatory processes that are comorbid with diseases accompanied by damage to the cartilaginous tissue [67][68][69][70][71].…”
