摘要:
The present invention provides an organotypic system comprising a portion of a retina containing live cells in a cultured in medium, wherein photosensitivity has been restored in at least some of said live cells. Methods of use thereof are also provided.
摘要:
The present invention relates to methods and compositions for inhibiting or stimulating angiogenesis. The invention shows the implication of Dp71 in angiogenesis and thus provides novel therapeutic approaches, as well as novel methods for screening agents modulating angiogenesis, which target this protein. More specifically, the present invention relates to the use of Dp71 or a variant thereof (or a coding nucleic acid) for stimulating angiogenesis in a subject, particularly a human subject. The invention relates to the use of an inhibitor of Dp71 for inhibiting angiogenesis in a subject.
摘要:
The present invention relates to taurine or taurine-like substances for the prevention of brain oedema, particularly brain intramyelinic oedema and more particularly brain intramyelinic oedema induced by an anti-convulsive drug such as vigabatrin. The invention relates to a substance selected from the group consisting of taurine, a taurine precursor, a taurine metabolite, a taurine derivative, a taurine analog and a substance required for the taurine biosynthesis for the prevention of brain oedema.

摘要:
The invention relates to an implant which includes, in order to electrically stimulate a nerve structure, in particular the retina, an electrically insulating substrate (1), a array of recesses (2) formed in an upper surface of the substrate, stimulation electrodes (3) arranged at the bottom of the recesses, and an electrically conductive layer forming a ground plane (4) at the upper portion of the recesses. The sizes of the recesses and of the electrodes of the implant are such that the spatial selectivity of the stimulation current applied to the nerve structure is maximized.
摘要:
The use of a substance selected from the group consisting of taurine, a taurine precursor, a taurine metabolite, a taurine derivative, a taurine analog and a substance required for the taurine biosynthesis, for manufacturing a pharmaceutical composition for preventing or inhibiting the undesirable side-effects caused to a human or an animal organism by an active ingredient that induces a high level of extracellular GABA or increases GABA receptor activation.
摘要:
The present invention provides a process and kit for isolating cone photoreceptor cells from retinal tissue with a purity level of at least 80%, typically of about 90%. The isolation process uses a PNA-panning procedure conducted on dissociated retinal tissue. The present invention also provides a culture medium enabling the in vitro survival and development of such isolated cone cells. The means of the invention are applicable to adult mammalian cone cells, and more particularly to adult human cone cells. They have the advantage of being applicable to pathologic or otherwise altered cone cells, and thus give access to the screening of compounds capable of showing neuroprotective activity on adult cone cells.

摘要:
The invention concerns the use of a calcium channel blocker compound and/or cyclic GMP-dependent channels, namely diltiazem, for treating retinal pathologies, and more particularly retinal diseases caused by degeneration of visual receptors, in a human or animal.
