Myelin Structure: Irregular

  Regions of myelin have MBP without P0 (Red)

P0 = Green; Myelin Basic Protein (MBP) = Red; Costain = Yellow

---

Axon Atrophy

  Axons in MBP stained myelin sheaths appear small
  See: Control

Neurofilament = Green; Myelin Basic Protein (MBP) = Red; Costain = Yellow

---

Axon Atrophy

  Many Myelinated axons (Green, no associated NCAM) are small

Neurofilament = Green; NCAM = Red; Costain = Yellow
