Remyelination in acute lesions involves the recruitment and maturation of oligodendrocyte progenitor cells (OPCs). However, remyelination fails in chronic lesions in part due to the failure of OPCs to mature into myelinating oligodendrocytes (OLs). Digestion products of the glycosaminoglycan hyaluronan (HA), generated by hyaluronidase activity within demyelinating lesions, are among the signals that block OPC maturation and remyelination. However, the identity and source of this hyaluronidase activity is unknown. 000042378 536__ $$oNIH$$cT32AG055378 000042378 536__ $$oNIH$$cT32GM071338 000042378 536__ $$oNMSS$$cRG-1702-27047 000042378 536__ $$oCDMRP MS$$cMS160144 000042378 540__ $$fCC BY-NC-SA 000042378 542__ $$fIn copyright - single owner 000042378 650__ $$aMultiple Sclerosis$$022506 000042378 650__ $$aHyaluronic Acid$$020392 000042378 650__ $$aExtracellular Matrix$$018796 000042378 650__ $$aMyelin Sheath$$022587 000042378 650__ $$aOligodendroglia$$023183 000042378 6531_ $$aoligodendrocyte 000042378 691__ $$aSchool of Medicine$$041369 000042378 692__ $$aDepartment of Cell, Developmental and Cancer Biology$$041399 000042378 7001_ $$aPeters, Alec$$uOregon Health and Science University$$041354$$10000-0003-1844-2870 000042378 7201_ $$aSherman, Lawrence$$uOregon Health and Science University$$041354$$eMentor$$7Personal 000042378 7201_ $$aCopenhaver, Philip$$uOregon Health and Science University$$041354$$eCommittee chair$$7Personal 000042378 7201_ $$aBarnes, Anthony$$uOregon Health and Science University$$041354$$eCommittee member$$7Personal 000042378 7201_ $$aBack, Stephen$$uOregon Health and Science University$$041354$$eCommittee member$$7Personal 000042378 7201_ $$aEmery, Ben$$uOregon Health and Science University$$041354$$eCommittee member$$7Personal 000042378 8564_ $$9da5c3ea5-7b7f-4d9e-8d31-5cfecfac59e0$$s4082391$$uhttps://digitalcollections.ohsu.edu/record/42378/files/Peters.Alec.2023.pdf 000042378 909CO $$ooai:digitalcollections.ohsu.edu:42378$$pstudent-work 000042378 980__ $$aTheses and Dissertations 000042378 981__ $$aPublished$$b2023-12-13
