Abstract:
The present invention provides proteins that are linked to glycosylphosphatidylinositol (GPI). The invention provides a fusion protein comprising a protein of interest and a carboxy-terminal glycosylphosphatidylinositol (GPI) anchor peptide sequence. Proteins of interest include neurotrophins such as BDNF. The invention also provides a fusion protein comprising a protein of interest, a linker peptide and a final carboxy-terminal residue, wherein the final carboxy-terminal residue is covalently linked to glycosylphosphatidylinositol (GPI). The GPI may be anchored to the membrane of an extracellular vesicle. Methods of making and using the fusion proteins and extracellular vesicles of the invention are also provided, including their use in therapy.
Abstract:
This invention relates to stem cell microparticles, their use and production, in particular neural stem cell microparticles and their use in therapy. The stem cell microparticle is typically an exosome or microvesicle and may be derived from a neural stem cell line. The neural stem cell line may be a conditionally-immortalised stem cell line such as CTX0E03 (deposited at the ECACC with Accession No. 04091601).
Abstract:
This invention relates to stem cell microparticles and miRNA isolated from these microparticles, their use and production thereof, in particular neural stem cell microparticles and their use in therapy of a disease or condition involving unwanted or undesirable cell migration. The stem cell microparticle is typically an exosome or microvesicle and may be derived from a neural stem cell line. The neural stem cell line may be a conditionally-immortalised stem cell line such as CTX0E03 (deposited at the ECACC with Accession No. 04091601).

Abstract:
The present invention uses neural stem cells in the manufacture of a medicament for the treatment of a patient suffering peripheral arterial disease. The invention is particularly suited for treating limb ischemia or Buerger's disease.
Abstract:
This invention relates to genetic engineering, in particular to an insertion site for a transgene, cells comprising a transgene or other modification at that insertion site, vectors for targeting that insertion site, and methods for creating transgenic cells by insertion or other modification at that site. The insertion site, or “safe harbour locus”, is identified within the SPATA13 gene on human chromosome 13q12.12. Mammalian cells comprising a genetic modification within the SPATA13 gene on chromosome 13q12.12 are described, wherein the modification may be an insertion such as an integrated transgene. Nucleic acid molecules able and adapted to guide the insertion of a transgene to that insertion site are also described. These cells or nucleic acids may be useful in therapy.
Abstract:
The invention relates to induced pluripotent stem cells that are generated from cells, for example Adult Stem Cells, that are conditionally-immortalisable. In particular, the invention relates to induced pluripotent stem cells generated from stem cell lines comprising a controllable transgene for conditional immortalisation, and the progeny of those induced pluripotent stem cells. Induced pluripotent stem cells, progeny cells derived from those pluripotent cells, compositions comprising those cells, methods of making all of those cells, and uses of all of those cells are also described.
Abstract:
The invention is based on the finding that microparticles can be produced by conditionally-immortalised cells. The conditionally-immortalised cells may be stem cells. The Examples show the successful harvest of microparticles from conditionally immortalised neural stem cells and CD34+ cells. Conditional immortalisation provides a constant supply of clonal cells that produce microparticles such as exosomes. The conditionally immortalised cells are useful as “producer cells” for microparticles such as exosomes, which are typically harvested or isolated from the conditionally-immortalised cells.
Abstract:
The subject invention pertains to methods to enhance the therapeutic effects of cellular or drug treatment in various diseases and disorders. More particularly, the present invention provides methods of treating disorders by administering CTX0E03 cells to the patient, intravenously or intraarterially. The treatment is useful for neurodegenerative diseases, such as stroke. The CTX0E03 cells may be cryopreserved and/or passaged before administration into the patient. Administration of the CTX0E03 cells into stroke rat models was at or within 48 hours after stroke. Testing of the rat models through elevated body swing test to measure of neurobehavioral status at the time of transplant and repeated triphenyltetrazolium chloride (TTC) staining as a measure of infarct volume showed short term survival that provided significant protection from the stroke.
Abstract:
The invention delivers exogenous nucleotide sequences into exosomes using structural and regulatory characteristics identified in the miRNA molecules MIR21, pri-miR-21 and pre-miR- 21. In particular, the invention relates to pre-miRNA for targeting an exogenous nucleotide sequence to an exosome, wherein the pre-miRNA comprises an exogenous nucleotide sequence and a stem-loop structure, wherein the stem comprises at least one wobble pair. The invention also provides nucleic acid cassettes, vectors and cells comprising the engineered pre-miRNA, methods of loading exosomes and the resulting loaded exosomes. The loaded exosomes can be used to deliver an exogenous nucleotide sequence to a target cell, for example in therapy.
