Macrophage responses and myelin clearance during Wallerian degeneration: relevance to immune-mediated demyelination.
Macrophages are important effector cells in immune-mediated demyelination. Current concepts regarding their entry and activation focus on the effects of T-cell-derived cytokines. This presentation describes the responses of macrophages and microglia to a non-inflammatory, non-immune injury, Wallerian degeneration. During Wallerian degeneration in the peripheral nervous system (PNS), macrophages...
متن کاملMR imaging of Wallerian degeneration in the brainstem: temporal relationships.
Degeneration of the myelin sheath and axon distal to the most proximal site of axonal interruption secondary to axonal disease has been called wallerian degeneration. On MR imaging, wallerian degeneration of the pyramidal tract can be observed as an abnormal signal intensity, showing prolonged T1 and T2 relaxation times that correspond to the corticospinal tract, with or without shrinkage of th...
متن کاملComplement depletion reduces macrophage infiltration and activation during Wallerian degeneration and axonal regeneration.
After peripheral nerve injury, macrophages infiltrate the degenerating nerve and participate in the removal of myelin and axonal debris, in Schwann cell proliferation, and in axonal regeneration. In vitro studies have demonstrated the role serum complement plays in both macrophage invasion and activation during Wallerian degeneration of peripheral nerve. To determine its role in vivo, we deplet...
متن کاملInvolvement of monocyte chemoattractant protein-1, macrophage inflammatory protein-1alpha and interleukin-1beta in Wallerian degeneration.
Wallerian degeneration in the CNS and PNS consists of degradation and phagocytosis of axons and their myelin sheath distal to the site of injury. This process of degeneration, which requires an effective macrophage response, occurs rapidly in peripheral nerves but is slow in the CNS. Rapid Wallerian degeneration in peripheral nerves may contribute to subsequent axonal regeneration. We show that...
