Titre: Combining Landsat and landscape metrics to analyse large-scale urban land cover change: a case study in the Jakarta Metropolitan Area Auteur:Wahyudi, Agung; Liu, Yan; Corcoran, Jonathan Sujet:Urban Land Cover Change ; Spatial Pattern ; Landscape Metrics ; Urban Growth ; Jakarta Metropolitan Area (Jma) ; Geography Description:
This study tests the capacity of Landsat imagery and landscape metrics to explore spatial and temporal dynamics of urban expansion in Jakarta Metropolitan Area (JMA), Indonesia, over 23-year period (1994-2017). Results show that JMA's urban area has doubled in size with average expansion of nearly 40 km 2 per annum, and urban area has grown into sparsely vegetated areas on the outskirts of Jakarta and along the east-west and southern corridors of JMA. Landscape metrics show that urban land cover has evolved into single-connected urban landscape in JMA's core while more fragmented urban pattern in the inner and outer municipalities.

Titre: Regulation of Myelination by Exosome Associated Retinoic Acid Release from NG2-Positive Cells Auteur:Goncalves, Maria B; Wu, Yue; Clarke, Earl; Grist, John; Hobbs, Carl; Trigo, Diogo; Jack, Julian; Corcoran, Jonathan P T Sujet:Ng2+ Cells ; Rarα ; Rarβ ; Decorin ; Exosome ; Myelination ; Retinoic Acid Description:
In the CNS, oligodendrocytes are responsible for myelin formation and maintenance. Following spinal cord injury, oligodendrocyte loss and an inhibitory milieu compromise remyelination and recovery. Here, we explored the role of retinoic acid receptor-beta (RARβ) signaling in remyelination. Using a male Sprague Dawley rat model of PNS-CNS injury, we show that oral treatment with a novel drug like RARβ agonist, C286, induces neuronal expression of the proteoglycan decorin and promotes myelination and differentiation of oligodendrocyte precursor cells (NG2 cells) in a decorin-mediated neuron-glia cross talk. Decorin promoted the activation of RARα in NG2 cells by increasing the availability of the endogenous ligand RA. NG2 cells synthesize RA, which is released in association with exosomes. We found that decorin prevents this secretion through regulation of the EGFR-calcium pathway. Using functional and pharmacological studies, we further show that RARα signaling is both required and sufficient for oligodendrocyte differentiation. These findings illustrate that RARβ and RARα are important regulators of oligodendrocyte differentiation, providing new targets for myelination. This study identifies novel therapeutic targets for remyelination after PNS-CNS injury. Pharmacological and knock-down experiments show that the retinoic acid (RA) signaling promotes differentiation of oligodendrocyte precursor cells (OPCs) and remyelination in a cross talk between neuronal RA receptor-beta (RARβ) and RARα in NG2 cells. We show that stimulation of RARα is required for the differentiation of OPCs and we describe for the first time how oral treatment with a RARβ agonist (C286, currently being tested in a Phase 1 trial, ISRCTN12424734) leads to the endogenous synthesis of RA through retinaldehyde dehydrogenase 2 (Raldh2) in NG2 cells and controls exosome-associated-RA intracellular levels through a decorin-Ca pathway. Although RARβ has been implicated in distinct aspects of CNS regeneration, this study identifies a novel function for both RARβ and RARα in remyelination.
