 Expression of one such molecule MAC-2, a galactose-specific lectin, is observed in not only degenerating nerves that are macrophage-rich but also degenerating nerves that are macrophage-scarce and Schwann cell-rich.Furthermore, the effects of MAC-2 in degenerating nerves are associated with myelin phagocytosis.There was a positive correlation between the amount of MAC-2 expression and the extent of myelin phagocytosis.
