The present invention relates to a kit-of-parts comprising and a composition comprising a polyplex comprising a double stranded RNA (dsRNA) and a polymeric conjugate comprising a polyethyleneimine (PEI), one or more polyethylene glycol (PEG) moieties and one or more targeting moieties, and wherein each of said one or more targeting moieties is capable of binding to a cancer antigen; and at least one antibody, wherein said at least one antibody is capable of modulating an immune checkpoint protein. Further the invention relates to this composition or kit-of-parts for use in the treatment of cancer.

The present disclosure is directed recombinant T cell receptors capable of binding a gp100 epitope and nucleic acid molecules encoding the same. In some embodiments, the nucleic acid molecules further comprise a second nucleotide sequence, wherein the second nucleotide sequence or the polypeptide encoded by the second nucleotide sequence inhibits the expression of an endogenous TCR. Other aspects of the disclosure are directed to vectors comprising the nucleic acid molecule and cells comprising the recombinant TCR, the nucleic acid molecule, or the vector. Still other aspects of the disclosure are directed to methods of using the same. In some embodiments, the methods comprise treating a cancer in a subject in need thereof.

The present disclosure relates to multi-specific molecules which are capable of simultaneously binding at least two different target antigens or epitopes. The molecules comprise at least one binding domain molecule (BDM) which hinds to a first target antigen or epitope, the BDM being modified for selective binding to a heterologous target, coupled to a pharmacologically active protein or peptide which is an antibody or antigen-binding fragment thereof or a non-antibody protein or peptide which binds to a second target antigen or epitope, the BDMs being coupled to a C-terminus of a polypeptide present within the pharmacologically active protein or peptide.

The present disclosure relates generally to the field of immunology. In particular, the disclosure relates to an immune cell expressing a CAR, wherein the immune cell has been modified such that the expression and/or function of LCK has been reduced or eliminated. The disclosure also relates to methods for treating a disease in a subject.

The present invention relates to novel proteins that specifically bind to the spike protein or domains thereof of the severe acute respiratory syndrome corona vims 2 (SARS-Cov-2) or variants of SARS-Cov-2. The proteins of the present invention represent advanced and powerful tools, for example for the purification of the virus or a vaccine for the virus, by virtue of said binding affinity for spike protein or domains of the spike protein of SARS-Cov-2 or variants thereof. Thus, the novel proteins of the present invention are particularly advantageous because they allow precise capturing of proteins or particles comprising spike proteins, S1 domain, and/or RBD in affinity chromatography. Further, the novel proteins of the present invention can be used in medical applications caused by or related to SARS-Cov-2 or variants thereof.

The disclosure provides fusion proteins specific for both CD137 and GPC3, which fusion protein can be used to co-stimulate lymphocyte activation in a GPC3-target-dependent manner. Such fusion proteins can be used in many pharmaceutical applications, for example, as anti-cancer agents and/or immune modulators for the treatment or prevention of human diseases such as a variety of tumors. The present disclosure also concerns methods of making the fusion proteins described herein as well as compositions comprising such fusion proteins. The present disclosure further relates to nucleic acid molecules encoding such fusion proteins and to methods for generation of such fusion proteins and nucleic acid molecules. In addition, the application discloses therapeutic and/or diagnostic uses of such fusion proteins as well as compositions comprising one or more of such fusion proteins.

The present invention relates to a cluster of differentiation 98 heavy chain (CD98hc)-specific binding protein, wherein the CD98hc-specific binding protein is a lipocalin 2 (Lcn2)-derived binding protein and binds to CD98hc with a K.sub.D of 200 nM or lower.

The present invention provides a fusion protein of an antigen-binding protein and a fluorescent protein or a fluorescence-labeled tag protein. The present invention provides a fusion protein of an antigen-binding protein and a fluorescent protein or a fluorescence-labeled tag, wherein the antigen-binding protein is an antigen-binding protein having a helix structure or a β-sheet structure at a terminus, the fluorescent protein or the fluorescence-labeled tag is a fluorescent protein or a fluorescence-labeled tag having a helix structure or a β-sheet structure at a terminus, and the helix at the terminus and the helix at the terminus are linked, or the β-sheet structure at the terminus and the β-sheet structure at the terminus are linked.
