Axonal Regeneration Group

After injury of our central nervous system (CNS), chondroitin sulfate (CS), a glial scar-associated glycan, transforms growth cones into "dystrophic endballs" through its receptor PTPRσ. Dystrophic endballs are terminally degenerated structures of axonal tips first identified and described by Cajal about 100 years ago. It completely lacks any ability for forward migration, thus, it has been believed to be responsible for failure of axonal regeneration of our CNS. However, underlying mechanisms of dystrophic endballs have been unclear.
We had focused on molecular and cellular mechanisms of dystrophic endball and had found that autophagosomes were abnormally accumulated in it.
