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 present invention relates to a method of identifying a subject having or at risk of having or developing a retinitis pigmentosa, comprising detecting in a sample obtained from said subject, the presence of at least one mutation in the rhodopsin (RHO) gene selected from the group consisting of c.263T>C, c.620T>A and c. 1031A>C wherein the presence of said mutation indicates an increased risk of having or being at risk of having or developing the retinitis pigmentosa.

摘要:
The inventors demonstrate that mRNA sorting to the mitochondrial surface is an efficient way to proceed to such an allotopic expression, and that this mRNA sorting can be controlled by selecting appropriate mitochondrion-targeting sequence (MTS) and appropriate 3′UTR sequences. The CDS sequence which codes for the protein to be delivered into the mitochondrion is guided by these appropriate MTS and 3′UTR sequences from the nuclear compartment to the mitochondrion-bound polysomes (where the CDS is translated), and aids in an efficient translocation of a mature functional protein into the mitochondria. Appropriate MTS and 3′UTR sequences correspond to those of nuclearly-transcribed mitochondrially-targeted mRNAs. The inventors demonstrate that, to obtain a stable therapeutically-effective importation, both an appropriate MTS and an appropriate 3′UTR should preferably be used.
