The present disclosure relates to isolated non-naturally occurring delivery constructs comprising a bacterial toxin-derived delivery construct coupled to a biologically active therapeutic cargo; wherein the delivery construct is capable of delivering the biologically active cargo via transcytosis transport across an epithelial cell; and wherein the delivery construct does not comprise a bacterial toxin-derived translocation domain or a bacterial toxin-derived catalytic (cytotoxic) domain.

The present invention provides a genetically modified NK cell line prepared by transducing host NK cell line with a gene construction encoding a cancer antigen-specific chimeric antigen receptor (CAR) comprising a FLT3-specific monoclonal antibody or a functional fragment thereof, a transmembrane domain, and a CD3ζ domain of a T-cell receptor for more efficient immunotherapy of acute myeloid leukemia, and use thereof, for more efficient immunotherapy of acute myeloid leukemia.

An immunotoxin for use in the treatment of leishmaniasis A wherein the immunotoxin comprises a portion which is specifically binding to the cellular surface receptor CD64 as a component A and a cell killing portion as a component B, wherein the cell killing portion alters the function, gene expression, or viability of a cell thereby killing Leishmania-infected macrophages and by this eliminates Leishmania.

The invention relates to a sensor molecule for detecting a target molecule comprising: (a) a rod-like molecule L and a rod-like molecule R connected to each other by a joint molecule C to form a hinge; (b) a target binding molecule A bonded to the end of rod-like molecule L opposite to the joint molecule C; (c) a binding molecule A′ bonded to the end of rod-like molecule R opposite the joint molecule C; wherein the target binding molecule A is arranged to bind to the target molecule to be detected, and binding molecule A′ is arranged to bind to: i) the same target molecule as target binding molecule A; or ii) a complex of the target binding molecule A and the target; and wherein the hinge is biased into an open position, such that target binding molecule A and binding molecule A′ are biased apart by the hinge.

The invention provides methods and compositions for enhancing the efficacy of cancer therapies through modulation of BAL1 and/or BBAP. Also provided are methods for predicting the efficacy of cancer therapies or treating cancer in a subject through modulation of BAL1 and/or BBAP. Further provided are methods for identifying compounds that are capable of modulating BAL1-BBAP complexes.

The present disclosure provides recombinant bacteria for production of indole-3-acetic acid (IAA). Pharmaceutical compositions and methods of treating diseases are also included.

Provided is a class of peptides which are useful for modulating the activity of poly (ADP-ribose) polymerase (PARP) and in particular for the treatment of cancer. The peptides include an active group and a cassette for delivering the active group to a cell. Also provided are peptides having an anionic group which is believed to act as a competitive inhibitor of proteases which cleave PARP.

Provided is a technique for synthesizing a nicotinamide derivative (NAm derivative) such as a nicotinamide mononucleotide (NMN) with high efficiency. A genetically modified microorganism is used, which can express, as nicotinamide phosphoribosylt ransferase (NAMPT), NAMPT having a conversion efficiency of 5-folds or more that of human NAMPT.

The present invention relates to high level expression of bacterial toxoid or toxin protein of pharmacological interest by means of an optimized novel polynucleotide sequence and host transformed with the said polynucleotide. Specifically, the invention provides a method for high production of polypeptide CRM.sub.197 wherein, the polynucleotide of the invention is used to transform a suitable host resulting in over-expression of corresponding proteins and a method for isolating the expressed polypeptide. More particularly, the present invention relates to high level expression of CRM.sub.197 in Escherichia coli and a method for the isolation and purification thereof.

The present invention pertains to a pharmaceutical composition comprising a recombinant measles virus encoding a suicide gene for use in the treatment of malignant cells with primary or secondary resistances against an oncolytic measles virus without suicide gene activity. Further, the present invention pertains to a recombinant measles virus based on measles vaccine strain Schwarz encoding a suicide gene, which comprises a fusion of a cytosine deaminase, particularly yeast cytosine deaminase, and a uracil phosphoribosyltransferase, particularly yeast uracil phosphoribosyltransferase, to a method and a kit for preparing the recombinant measles virus as claimed herein.
