MODIFIED INTERLEUKIN-7 PROTEINS AND USES THEREOF

Provided are a modified IL-7 polypeptide and a fusion protein containing the modified IL-7 polypeptide. The fusion protein of the modified IL-7 includes: a first domain containing an interleukin-7 polypeptide; a second domain containing an oligopeptide having 1 to 10 amino acid residues (with proviso that the second domain excludes the oligopeptide consisting of methionine and/or glycine); and (c) a third domain which prolongs the half-life of the IL-7 fusion protein. The modified IL-7 polypeptide is composed of the (a) first domain and the (b) second domain. The modified IL-7 polypeptide and the fusion protein are expressed in a higher yield than the wild-type IL-7 and shows increased stability.

Cysteine Chemistry in Connection with Abiogenesis

Theoretical and experimental work has been conducted about possible prebiotic syntheses of cysteine. Activated derivatives of this amino acid can oligomerize and polymerize to afford various poly-thiazolines and cysteine-rich chains.

T Cells with Increased Immunosuppression Resistance

This invention relates to the treatment of cancer in an individual by administration of a population of modified T cells that express a recombinant cAMP phosphodiesterase (PDE) or a fragment thereof and an antigen receptor which binds specifically to cancer cells in the individual. Populations of modified T cells and methods of producing populations of modified T cells are provided, along with pharmaceutical compositions and methods of treatment
