Risk Factors for Proteinuria. Both diabetes and high blood pressure can cause damage to the kidneys, which leads to proteinuria. Other types of kidney disease unrelated to diabetes or high blood pressure can also cause protein to leak into the urine. Increased production of proteins in the body can lead to proteinuria.
Depending on the location, different glial cell types make myelin in a different manner. Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and spinal cord). In the PNS, one Schwann cell forms a single myelin sheath (Figure 1A).he nervous system is comprised of two primary cell types: neurons and glial cells. These cells communicate with each other to perform important tasks in the nervous system. The glial cells support neurons structurally and maintain their long-term neuronal integrity, and neurons regulate glial cell behavior.
Thus, the key difference between Schwann cells and myelin. sheath is that Schwann cells are the peripheral nervous system cells which. form the myelin sheath around the axon while myelin sheath is an electrically. insulating layer wrapped around the axon, which increases the speed of. electric conduction.
