Molecules inhibiting neurite growth: a minireview.
Molecules and activities which repulse growing neurites or induce growth cone collapse and long-lasting growth inhibition have been defined over the last 10 years. Recently, specific guidance roles for developing axons and pathways could be associated with such repulsive effects. A high molecular weight membrane protein located in CNS myelin acts as potent neurite growth inhibitor and may play a role as a negative control element for sprouting, neurite growth and regeneration, and for the plasticity of the adult CNS. Interestingly, some guidance molecules can have positive, growth-promoting as well as negative, repulsive effects for specific types of neurons. These results underline the complex mechanisms involved in neurite guidance which depends on the interpretation of combinations of incoming signals by particular growth cones.
