WebJun 9, 1995 · Abstract. Progesterone is shown here to be produced from pregnenolone by Schwann cells in peripheral nerves. After cryolesion of the sciatic nerve in male mice, axons regenerate and become myelinated. Blocking either the local synthesis or the receptor-mediated action of progesterone impaired remyelination. Administration of progesterone … WebThese disorders encompass defects in the generation, maintenance, and repair of white matter, and the primary molecular deficit may arise not only in myelin-producing oligodendrocytes but also in astrocytes, microglia, or other cell types. 1–3 Several informative reviews published in the last several years provide broad overviews of …

Myelin structure not only increases the conduction velocity of action potentials [22], but also interacts with axons to support neuronal survival and modulate neurotransmission [13, 34, 39]. OLGs also synthesize neurotrophic factors to promote neuronal survival and axonal growth [46]. Recently, OLG-myelin complex has attracted new
WebSep 4, 2014 · -Synthesize and evaluate a novel imaging agent for Near Infrared Fluorescence Imaging (NIRF) research, for detecting the changes of myelin sheaths content in the small animals. The process of generating myelin is called myelination or myelinogenesis. In the CNS, oligodendrocyte progenitor cells (OPCs) differentiate into mature oligodendrocytes, which form myelin. In humans, myelination begins early in the 3rd trimester, although only little myelin is present in either the CNS or the PNS at the time of birth. During infancy, myelination progresses rapidly, with increasing numbers of axons acquiring myelin sheaths. This corresponds with the d…
