Sirt2tm1.1Auw/Sirt2tm1.1Auw Tg(Mpz-cre)26Mes/0 mice display hypomyelination

nervous system
• however, axon regeneration is normal
• remyelination following nerve crush injury is delayed compared to in wild-type mice
• mice exhibit a transient delay in myelination compared with wild-type mice
• the sciatic nerve is hypomyelinated at P1, P3, and P5
• at P21 and P28, mice exhibit extensive outfoldings in compact myelin located in close vicinity to the paranode
• following nerve crush injury, mice exhibit reduced myelination compared with wild-type mice
• however, mice exhibit normal myelination at P7 and remyelination following nerve crush injury after 28 days

homeostasis/metabolism
• however, axon regeneration is normal
• remyelination following nerve crush injury is delayed compared to in wild-type mice

behavior/neurological
N
• mice exhibit normal function on a rotarod, grip strength, and thermal nociception
