Diverse roles of macrophages in intraocular neovasculardiseases:a review

引用

International Journal of Ophthalmology(English edition) 2017年第12期10卷 1902-1908页

Macrophages are involved in angiogenesis, and might also contribute to the pathogenesis of intraocular neovascular diseases. Recent studies indicated that macrophages exert different functions in the process of intraocular neovascularization, and the polarization of M1 and M2 phenotypes plays extremely essential roles in the diverse functions of macrophages. Moreover, a large number of cytokines released by macrophages not only participate in macrophage polarization, but also associate with retinal and choroidal neovascular diseases. Therefore, macrophage might be considered as a novel therapeutic target to the treatment of pathological neovascularization in the eye. This review mainly summarizes diverse roles of macrophages and discusses the possible mechanisms in retinal and choroidal neovascularization.

Attenuation of periostin in retinal Müller glia by TNF-α and IFN-γ

引用

International Journal of Ophthalmology(English edition) 2019年第2期12卷 212-218页

作者： Ying-Qian Peng Man-Jing Cao Shigeo Yoshida Lu-Si Zhang Hui-Lan Zeng Jing-Ling Zou Yoshiyuki Kobayashi Takahito Nakama Jing-Ming Shi Song-Bai Jia Ye-Di Zhou Department of Ophthalmology the Second Xiangya Hospital Central South University Hunan Clinical Research Center of Ophthalmic Disease Department of Ophthalmology Kyushu University Graduate School of Medical Sciences Department of Ophthalmology Kurume University School of Medicine

AIM: To investigate the regulation and mechanisms of periostin expression in retinal Müller glia, and to explore the relevance to retinal neovascularization. METHODS: The oxygen-induced retinopathy(OIR) mouse model and the human Moorfield/Institute of Ophthalmology-Müller 1(MIO-M1) cell line were used in the study. Immunofluorescence staining was used to determine the distribution and expression of periostin and a Müller glial cell marker glutamine synthetase(GS). Cytokines TNF-α and IFN-γ were added to stimulate the MIO-M1 cells. ShRNA was used to knockdown periostin expression in MIO-M1 cells. Quantitative real-time reverse transcription polymerase chain reaction(qRT-PCR) was conducted to assess the mRNA expression of periostin. RESULTS: Immunofluorescence staining showed that periostin was expressed by MIO-M1 Müller glia. GS-positive Müller glia and periostin increased in OIR retinas, and were partially overlaid. The stimulation of TNF-α and IFN-γ reduced the mRNA expression of periostin significantly and dose-dependently in MIO-M1 cells. Knockdown of periostin reduced mRNA expression of vascular endothelial growth factor A(VEGFA) in MIO-M1 cells, while VEGFA expression was not changed in periostin knock-out OIR retinas. CONCLUSION: Müller glia could be one of the main sources of periostin in the retina, and might contribute to the pathogenesis of retinal neovascularization. Proinflammatory cytokines TNF-α and IFN-γ attenuate the periostin expression in retinal Müller glia, which provides a potential and novel method in treating retinal neovascular diseases.

Fluorescence quantum yield of Gd_(0.9-x)R_xEu_(0.1)OOH(R=Y, La) crystals

引用

Journal of Rare Earths 2015年第12期33卷 1256-1260页

作者： Hiroaki Samata Katsutoshi Kobayashi Masashi Hanioka Tadashi C.Ozawa Graduate School of Maritime sciences Kobe University Materials Development Group Superconducting Properties Unit National Institute for Materials Science

*** （R=Y, La） crystals were synthesized by a flux method using a mixture of NaOH and KOH as the flux. X-ray diffraction data were well refined using the Rietveld method assuming that the crystals had a monoclinic structre belonging to the P21/m space group. The unit cell volumes of the Gdo.9 *** crystals increased with increasing x, whereas those of *** decreased with increasing x. The Commission Internationale de IEclairage （CIE） chromaticity coordinates of Gdo.9 *** （R=Y, La） crystals were located in the red region and were nearly constant over the range ofx values considered. The fluorescence quantum yield Dr monotonically decreased with increasing x regardless of the ionic radii of the substitute ions. The fact that the Dr value of Lao.9EuoAOOH was greater than that of *** indicated that the observed decrease in the values of the Gdo.9-,LaxEuo.1OOH crystals up to x=0.3 could not be attributed to an increase in the distance between Eu3＋ ions or to a decrease in the Gd3＋ content. The decrease might be due to an increase of killer centers introduced by elemental substitutions with the larger ion.
