眼外來源的少突膠質(zhì)細(xì)胞參與斑馬魚視網(wǎng)膜髓鞘化以及眼動反應(yīng)
[Abstract]:In most mammals, there is no myelin sheath in the retina. The abnormal appearance of oligodendrocyte in the eye can form white or Gray Striped plaques in the ganglion cell layer. The presence of myelin sheath in the retina may lead to some visual impairment, such as myopia and amblyopia in the retina. Although myelination occurs in the retina of some lower vertebrates, the temporal and spatial dynamics of myelination, the origin of oligodendrocytes, the behavior of oligodendrocytes during myelination and the function of oligodendrocytes have not been clearly explained. This will provide detailed information on the formation of intraretinal myelin sheath in zebrafish. Due to the lack of oligodendrocyte-specific markers in transgenic animal strains, the study of myelin sheath is limited to the identification of different developmental stages by immunohistochemistry. The presence of oligodendrocytes and myelin sheaths in the retina of zebrafish and the presence of multiple transgenic strains of myelin markers make it a good vertebrate model for studying the development of intraretinal myelin sheaths. We found that myelin began to form in the retina of zebrafish on the 28th day after birth. With the development of oligodendrocytes in the retina of zebrafish, the number of ganglion cells increased; the density of oligodendrocytes and the expression of myelin basic protein (MBP) increased with development. The proportion of ganglion cells and oligodendrocytes decreased and remained stable until the third month after birth. With regard to the origin of oligodendrocytes in the retina, DiI dye was injected into the third ventricle of the chicken, Ono et al. found that there were DiI positive oligodendrocytes in the retina. It is suggested that oligodendrocytes may originate from the outside of the eyeball. However, previous studies do not prove whether all myelin sheaths in the retina originate from the outside of the eyeball. Intramembranous stem cells. Using optic nerve transplantation, we can observe the morphology of individual oligodendrocytes in the retina. We found that oligodendrocytes of different ages behave differently: young oligodendrocytes form longer internodes; adult oligodendrocytes form smaller internodes. Age-related changes in oligodendrocyte behavior depend on the intrinsic characteristics of oligodendrocyte rather than on the external environment. Despite differences in oligodendrocyte behavior at different ages, their ability to encapsulate myelin sheaths has not changed significantly. Although the diameter of myelin-encapsulated axons varies with age Unlike other central nervous systems, the myelin sheath in the retina of zebrafish is loosely wrapped in a single loop. The ratio of the inner diameter of the axon to the outer diameter of the axon (the sum of the inner diameter of the axon and the thickness of the myelin sheath) remains between 0.6 and 0.7. Formula 1 may be important for maintaining optical transparency of the retina and facilitating nerve impulsive conduction. Using zebrafish eye behavior experiments and hemolytic lecithin-induced intraretinal demyelination model, we found that intraretinal myelin sheath of zebrafish has an effect on zebrafish eye movement. Myelin formation in the retina of zebrafish begins 28 days after fertilization; all oligodendrocytes in the retina originate from the outside of the eyeball; different oligodendrocytes behave differently, which is determined by the intrinsic factors of the cells; and the myelin sheath in the retina of zebrafish is functional. The inner myelin sheath and its physiological characteristics provide more details.
