    • A characteristic subset of microglia expressing CD11c appears in response to brain damage. However, the functional role of CD11c(+) microglia, as well as the mechanism of its induction, are poorly understood. Here we report that the genetic ablation of signal regulatory protein alpha (SIRP alpha), a membrane protein, induced the emergence of CD11c(+) microglia in the brain white matter. Mice lacking CD47, a physiological ligand of SIRP alpha, and microglia-specific SIRP alpha-knockout mice exhibited the same phenotype, suggesting that an interaction between microglial SIRP alpha and CD47 on neighbouring cells suppressed the emergence of CD11c(+) microglia. A lack of SIRP alpha did not cause detectable damage to the white matter, but resulted in the increased expression of genes whose expression is characteristic of the repair phase after demyelination. In addition, cuprizone-induced demyelination was alleviated by the microglia-specific ablation of SIRP alpha. Thus, microglial SIRP alpha suppresses the induction of CD11c(+) microglia that have the potential to accelerate the repair of damaged white matter.

  • OceanGliders: A component of the integrated GOOS

    • The OceanGliders program started in 2016 to support active coordination and enhancement of global glider activity. OceanGliders contributes to the international efforts of the Global Ocean Observation System (GOOS) for Climate, Ocean Health and Operational Services. It brings together marine scientists and engineers operating gliders around the world: (1) to observe the long-term physical, biogeochemical, and biological ocean processes and phenomena that are relevant for societal applications; and, (2) to contribute to the GOOS through real-time and delayed mode data dissemination. The OceanGliders program is distributed across national and regional observing systems and significantly contributes to integrated, multi-scale and multi-platform sampling strategies. OceanGliders shares best practices, requirements, and scientific knowledge needed for glider operations, data collection and analysis. It also monitors global glider activity and supports the dissemination of glider data through regional and global databases, in real-time and delayed modes, facilitating data access to the wider community. OceanGliders currently supports national, regional and global initiatives to maintian and expand the capabilities and application of gliders to meet key global challenges such as improved measurement of ocean boundary currents, water transformation and storm forecast.
