Peripheral nerve myelination
WebThis protein is found in the peripheral nervous system, which connects the brain and spinal cord to muscles and to sensory cells that detect sensations such as touch, pain, heat, and sound. The PMP22 protein is a component of myelin, a protective substance that covers nerves and promotes the efficient transmission of nerve impulses. WebJun 25, 2002 · To study the process of peripheral nerve myelination after injury, microarray time courses were generated following nerve crush and transection, paradigms in which the state of myelination is dynamically changing. The sciatic nerve was chosen for its accessibility and relative homogeneity and predominance of Schwann cells. An …
