Perineural network (PNN) is a structure containing chondroitin sulfate proteoglycan on the surface of neurons, which is related to neural plasticity and memory control
Wherein the chondroitin-4-sulfate, having the effect of inhibiting the network, can inhibit neuronal plasticity; andchondroitin-6-sulfate, may promote neuronal plasticity
A study published in Molecular Psychiatry on July 16, 2021 found that restoring chondroitin 6-sulfate (C6S) levels in elderly animals can rescue memory deficits and restore cortical long-term enhancement.
Restoring chondroitin 6-sulfate (C6S) levels in elderly animals on Molecular Psychiatry on Molecular Psychiatry can rescue memory deficits and restore long-term cortical enhancement.
In this study , the team observed 20-month-old mice , and compared with 6-month- old mice , these mice had memory deficits
In this study , the team looked at a large 20-month mouse , and the 6-month rat , and the six-month old mice old mice compared to the mice's memory defect occurs

In order to further explore the chondroitin-6-sulfate in the role of memory loss effect of memory loss , researchers cultivated in mice after genetic manipulation ( chst3) changes to simulate aging
Age-mediated memory loss in C57bl/6 mice and restoration of SOR memory by injection of AAV1- Chst3 into PRh
Age-mediated memory loss in C57bl/6 mice and restoration of SOR memory by injection of AAV1- Chst3 into PRhChst3Professor James Fawcett of the John van Geest Brain Repair Center at the University of Cambridge said: "It is exciting that although our research is only in mice, the same mechanism should work in humans- because of the structure of the human brain and the brain The molecule is the same as that of rodents , which suggests that it is possible to prevent memory loss in humans in old age

And the team has identified a potential drug, already approved for human use for human use , can be administered orally and inhibit the formation of PNN
