The present invention is concerned with orthogonal translation systems which allow for the site-specific introduction of non-canonical amino acid residues into a target protein (POI) in a POI-mRNA-selective manner. Specifically, the present invention relates to assembler fusion proteins which bring an RNA-targeting polypeptide (RNA-TP) segment and an orthogonal aminoacyl tRNA synthetase (O-RS) segment into spatial proximity of one another, either by direct linkage in RNA-TP/O-RS fusion proteins, or though the action of “assemblers” fused to each of these segments in assembler fusion proteins (AFPs). The invention also relates to AFP combinations and nucleic acid molecules comprising a POI-encoding sequence together with a targeting nucleotide sequence that is able to interact with an RNA-TP. The invention further relates to nucleic acid molecules, expression cassettes and expression vectors encoding said RNA-TP/O-RS fusion proteins or AFPs, cells comprising same, as well as methods and kits for translationally preparing POIs.

The present disclosure provides immunomodulatory fusion proteins-metal hydroxide complexes comprising an immunomodulatory domain adsorbed to a metal hydroxide via ligand exchange. The disclosure also features compositions and methods of using the same, for example, to treat cancer.

Transgenic microalgae expressing at least one exogenous biologically active protein. The protein-expressing microalgae are used for the oral delivery of the biologically active protein to the target organism in its intact and functional form. The exogenous protein, expressed in algae, is characterized by being biologically active, exerting at least one specific activity having a beneficial effect on the subject consuming the algae. The transgenic microalgae are used as animal food for aquatic or land animals welfare or as food supplement for human healthcare.

The present invention provides compositions comprising an anti-CD7 chimeric activating receptor (CAR) and an anti-CD7 protein expression blocker, and methods of using such compositions in cancer therapy.

Disclosed are compositions comprising an antibody conjugated to one or more molecular guidance system (MGS) peptides. Disclosed are methods of treating a subject in need thereof comprising administering to the subject in need thereof an effective amount of an antibody conjugated to one or more MGS peptides, wherein the antibody targets an intracellular target involved in the disease process. Disclosed are methods of targeting an intracellular target comprising administering an antibody conjugated to one or more MGS peptides, wherein the antibody targets an intracellular target.

The present invention provides Shiga toxin A Subunit derived polypeptides, scaffolds, and cell-targeting molecules comprising amino acid substitutions which equip the molecules with site-specific positions (and often unique amino acid residues in the molecule) for linking other molecules while retaining Shiga toxin function(s), such as, e.g., efficient intracellular routing and/or potent cytotoxicity. The present invention also provides cell-targeting molecules, and/or components thereof, which comprise site-specific positions for linking other molecules, such as, e.g., agents that alters a property of the cell-targeting molecule or a cargo for delivery. Certain molecules comprising a polypeptide of the present invention exhibit reduced immunogenicity and/or are well-tolerated by mammals. The cell-targeting molecules of the present invention, and compositions thereof, have uses, e.g., for the selective delivery of cargos to target-expressing cells and as diagnostic and/or therapeutic molecules for the treatment of a variety of diseases, disorders, and conditions, which include genetic disorders, genetic predispositions, infections, cancers, tumors, growth abnormalities, and/or immune disorders.
