Diverse functions of perineuronal nets.
Perineuronal nets represent well-organised components of the extracellular matrix, which are surrounding cell bodies, dendrites, and axon segments of a particular class of neurones as well as forming lattice-like structures. The role of perineuronal nets is not fully elucidated yet. Perineuronal nets may play a beneficial role by stabilizing the extracellular milieu assuring the characteristic features of enveloped neurons and protecting them from the influence of harmful agents. On the other hand, perineuronal nets create a barrier which limits neuronal plasticity and counteracts regeneration. This review examines recent evidence concerning the significance of the occurrence of perineuronal nets.
