Application

Nogo-66(1-40) antagonist peptide has been used as a Nogo-66 receptor antagonist peptide:
  • to study the preliminary therapeutic effect after inhibition of Nogo-A in the cauda equina compression (CEC) model
  • to determine the effects of Nogo-A/NgR1 on autophagic activation
  • to study its role in Nogo-B mediated axonal branching using Schwann cells and sensory neurons of mice

Actions biochimiques/physiologiques

Myelin-derived axon outgrowth inhibitors, such as Nogo, may account for the lack of axonal regeneration in the central nervous system (CNS) after trauma in adult mammals. Nogo-66 can inhibit axonal outgrowth through an axonal Nogo-66 receptor (NgR). Competitive antagonists of NgR derived from amino-terminal peptide fragments of Nogo-66. The Nogo-66(1 40) antagonist peptide (NEP1 40) blocks Nogo-66 or CNS myelin inhibition of axonal outgrowth in vitro, demonstrating that NgR mediates a significant portion of axonal outgrowth inhibition by myelin. Intrathecal administration of NEP1 40 to rats with mid-thoracic spinal cord hemisection results in significant axon growth of the corticospinal tract, and improves functional recovery. Thus, Nogo-66 and NgR have central roles in limiting axonal regeneration after CNS injury, and NEP1-40 provides a potential therapeutic agent.

Focal cerebral infarction leads to autophagic activation, which contributes to secondary neuronal damage in the ipsilateral thalamus. Although Nogo-A deactivation enhances neuronal plasticity, its role in autophagic activation in the thalamus after ischemic stroke remains unclear. This study aimed to

In contrast to the central nervous system (CNS) nerve fibers do regenerate in the peripheral nervous system (PNS) although in a clinically unsatisfying manner. A major problem is excessive sprouting of regenerating axons which results in aberrant reinnervation of target
