Conditional deletion of Id2 or Notch1 in oligodendrocyte progenitor cells does not ameliorate disease outcome in SOD1G93A mice.


ABSTRACT: Oligodendrocytes are essential for structural and trophic support of motor axons. Their impairment has been implicated in amyotrophic lateral sclerosis (ALS), a neurodegenerative disorder of motor neurons. Oligodendrocyte progenitor cells fail to differentiate into mature oligodendrocytes and thereby jeopardize the health of motor neurons. Here, we report that oligodendrocytic ablation of inhibitor of DNA binding 2 (Id2) or Notch receptor 1 (Notch1), 2 negative master modulators of oligodendrocyte differentiation, fails to alleviate oligodendrocyte dysfunction or alter disease outcome in a murine model of ALS. Our data suggest that these inhibitors are not suitable targets for intervention in ALS.
