Schwann Cells as Crucial Players in Diabetic Neuropathy

WebTools Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath) [1] is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. It forms the outermost layer of the nerve fiber in the peripheral nervous system. [2] WebImagine that a Schwann cell is a pillow with the pillowcase representing Schwann cell membrane and the pillow's stuffing representing Schwann cell nucleus and cytoplasm. Next imagine a broomstick (representing the axon) lying across one end of the pillow. WebA decrease in unmyelinated and small myelinated axons appeared earlier than a decrease in large myelinated fibers in diabetic neuropathy. Electron microscopic studies of human diabetic neuropathy demonstrated edematous cell cytoplasm, aggregates of glycogen particles, and hyperplasia of the surrounding basal lamina in Schwann cells. file server free download
