The present invention pertains to a silkworm-type biotinylated CTLD14 or sRAGE and a method for manufacturing the same. One embodiment of the present invention provides a method for manufacturing biotinylated proteins, wherein the method includes A) a step for inserting a nucleic acid molecule for coding biotin ligase and protein in a coexpressable manner into a silkworm or a living organism that imparts sugar chains that are the same as the sugar chains of the silkworm, B) a step for causing the biotin ligase and protein to be expressed by disposing the silkworm or the living organism that imparts sugar chains that are the same as the sugar chains of the silkworm to conditions with which the nucleic acid molecule will carry out expression, and C) a step for administering biotin to the living organism and obtaining the biotinylated protein.

This disclosure concerns production of product peptides with a target amino acid sequence by proteolysis of a recombinant polypeptide comprising specific protease recognition sites or chemical cleavage sequences. In some embodiments, the product peptide is released from repeating peptide units in the recombinant polypeptide by removal of intervening amino acid sequences by proteolysis by proteases that recognize sites within the intervening amino acid sequences and a carboxypeptidase, aminopeptidase, and/or further protease.

The present invention relates to a targeting module comprising at least one PD-L1 and/or PD-L2 binding domain, and a tag-binding domain or a tag for use in a method for stimulating a chimeric antigen receptor mediated immune response in a mammal, a nucleic acid, a vector or a cell comprising a nucleotide sequence encoding the targeting module, a pharmaceutical composition and a kit comprising the targeting module and a vector or a cell comprising a nucleotide sequence encoding a switchable chimeric antigen receptor.

The present invention provides a combination comprising a) an antigen binding domain specific for CD90, and b) an antigen binding domain specific for CD326, for use in treatment of human cancer comprising cancerous cells that co-express CD90 and CD326. In one embodiment of the invention the combination comprises a) an immune cell comprising a CAR comprising an antigen binding domain specific for a tag of a first and a second polypeptide, b) said tagged first polypeptide that has an antigen binding domain specific for CD90, and c) said tagged second polypeptide that has an antigen binding domain specific for CD326, wherein the tag of the first polypeptide and the tag of the second polypeptide are identical. In a further embodiment the concentrations used for said first and that second polypeptide are below the activation threshold of said CAR, respectively, but the sum of both concentrations is above the activation threshold of said CAR.

Methods for the rapid elimination of carbon monoxide (CO) from CO-bound hemoglobin, myoglobin and cytochrome c oxidase in subjects with CO poisoning are described. The disclosed therapy involves the use of rationally designed, modified, regulator of CO metabolism (RcoM) proteins and pharmaceutical compositions thereof, which scavenge carbon monoxide from poisoned tissue. The recombinant RcoM compositions are infused into blood, where they rapidly sequester carbon monoxide and limit the toxic effects of carbon monoxide on cellular respiration, oxygen transport and oxygen utilization.

This invention relates to transduction of cargo molecules into living cells, such as protein transduction, in particular a delivery molecule for transduction of a cargo into a cell comprising: a cargo-binding molecule and/or a cargo; a glycosaminoglycan (GAG) binding element, which is capable of binding to GAG on the surface of the cell; and a protein transduction domain. Methods of transduction, methods of producing or modifying cargo for transduction, delivery molecules for transduction and methods of treatment using transduction, or using transduced cells are also provided.

Engineered trimeric CD70 proteins for use in ex vivo T cell manufacturing are described. Use of the proteins during manufacturing creates expanded T cell populations with enhanced properties such as earlier proliferation in culture; selective expansion of nave and memory T cell subsets; longer persistence in vivo following administration to a subject; and improved therapeutic effect. Use of the proteins as therapeutics provide anti-cancer and anti-viral effects. The proteins can also be used as agonistic cell culture reagents in in vitro uses.

Provided is a recombinant polypeptide comprising a resistin trimerization domain and a polypeptide of interest. Further provided is an expression vector encoding the recombinant polypeptide and a method of expressing the recombinant polypeptide. The polypeptide of interest may be a trimeric viral surface antigen or a portion thereof, such as the ectodomain of the SARS-CoV-2 spike protein. Further provided are compositions, such as immunogenic compositions and vaccines, comprising the recombinant polypeptide.

The present disclosure provides conjugates and systems for modulating the activity of a ligand-binding polypeptide such as a D1 dopamine receptor. The present disclosure provides methods of modulating the activity of a D1 dopamine receptor. The present disclosure provides methods of treating Parkinson’s disease in an individual.
