Title: Episomal expression cassettes for gene therapy
Usefulness: Episomal expression cassettes for gene therapy
Summary: USE EC, and the liposomes, are used in gene therapy of lung diseases (by delivery to submucosal pulmonary epithelial cells), specifically cystic fibrosis (CF) but also epithelial cancers and emphysema (e.g. where (I) expresses an angiogenesis inhibitor or interleukin-10). Other uses include research (in vitro or in animal models); producing proteins, and gene therapy of other diseases, e.g. cancer of colon or breast, including expression of antisense sequences.
Novelty: New episomal expression cassette for expressing transgene in epithelial cells liposomes and transfected cells containing it, and transfected lung tissue, especially for gene therapy of cystic fibrosis
