Paired Immunoglobulin-like Receptor B Knockout Does Not Enhance Axonal Regeneration or Locomotor Recovery after

Myelin components that inhibit axonal regeneration are be-lieved to contribute significantly to the lack of axonal regener-ation noted in the adult central nervous system. Three pro-teins found in myelin, Nogo, myelin-associated glycoprotein,and oligodendrocyte-myelin glycoprotein, inhibit neurite out-growth
