The disclosure relates to fusion proteins comprising a tBID polypeptide and a steroid hormone receptor domain, and methods of using same to induce apoptosis in cells.

Single-domain antibodies that bind the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) spike protein are disclosed. The single-domain antibodies include binding domains that bind epitopes of the Spike ectodomain inside and outside the receptor binding domain. The single-domain antibodies can be used for multiple purposes including in the research, diagnosis, and prophylactic or therapeutic treatment of COVID-19.

The invention provides an invasive recombinant bacterial cell for use in prevention and/or treatment of an immune-related disorder; said bacterial cell comprising one or more recombinant nucleic acid molecule(s) encoding one or more therapeutic agent(s) for use in prevention and/or treatment of said immune-related disease in a mammal in need thereof.

Provided herein is a chimeric antigen receptor (CAR) and CAR-expressing immune cells that target human RORI expressed aberrantly on a tumor cancers. Described herein are chimeric antigen receptors that target human ROR-1, cell compositions expressing the chimeric antigen receptors, and methods and uses of the chimeric antigen receptors and/or the cell compositions. The chimeric antigen receptors described herein can be expressed by the T lymphocytes isolated from an individual afflicted with cancer and re-administered to the individual.

The present disclosure relates in some aspects to chimeric signaling receptors containing an extracellular domain capable of binding a molecule, such as an immunosuppressive cytokine, and a MyD88-containing intracellular domain capable of engaging a signaling pathway to activate an immune cell. In some aspects, the disclosure further relates to engineered cells, such as T cells, and compositions comprising the chimeric signaling receptors or engineered cells, and methods and uses thereof. In some embodiments, the cells may further express a genetically engineered recombinant antigen receptor directed against an antigen, such as a chimeric antigen receptor (CAR) or recombinant T cell receptor (TCR) and, in some cases, secrete a recombinant molecule, for example, a bispecific antibody.

The present invention provides a use of IFN-γ in preparing an anti-tumor adjuvant drug, wherein the IFN-γ enhances killing effect of the T cell preparation on tumor cell by sensitizing the tumor cell; the T cell preparation comprises non-genetically engineered T cell and/or genetically engineered T cell; and the IFN-γ comprises full-length or fragment of wild-type or mutant IFN-γ. The present invention revises the current understanding of IFN-γ in the prior art and finds that the IFN-γ inhibits the acquired immune resistance mediated by PD-L1-PD-1 and enhances the anti-tumor effect of immunotherapy by activating the IFN-γ signaling pathway in tumor cell.

The present invention inter alia relates to a method of selecting a patient for treatment of a solid tumor, wherein cells of the tumor express the human melanoma associated antigen 1, to a method of predicting whether a patient being diagnosed with a MAGE-1A positive solid tumor will be responsive to treatment of this tumor as well as to methods of treating a patient being diagnosed with a MAGE-1A solid tumor. The invention also relates to a pharmaceutical composition comprising T cells expressing a T cell receptor that specifically binds MAGE-1A and to a diagnostic immunostaining kit for selecting a patient for treatment of a solid tumor.

The present disclosure provides an anti-EpoR peptide for use in the treatment of a disease such as cancer. In the description, a peptide which has the structure: -[SCHFGPLTWVCK]- and which is intended to be used for antagonizing an Epo heteroreceptor selectively in the presence of erythropoietin (Epo) or an equivalent thereof, a modified peptide of the peptide, a prodrug of the modified peptide, or a salt of the peptide, the modified peptide or the prodrug (wherein, in the formula, an alphabetical letter represents a one-letter code for an amino acid residue) is provided. In one embodiment, a disease, a disorder or a symptom each characterized by the occurrence of a cell expressing an Epo heteroreceptor is treated or prevented.

The disclosure relates to an anti-CD133 single-chain antibody. The amino acid sequence of the anti-CD133 single-chain antibody comprises a sequence shown in SEQ ID NO. 1. T lymphocytes expressing the anti-CD133 single-chain antibody can specifically kill CD133-positive tumor cells and have higher specificity and stronger killing ability.

Provided are a method for engineering T-cells or pluripotent stem cells, as well as engineered T-cells and pluripotent stem cells. The method specifically comprises: engineering the T cells or pluripotent stem cells to obtain engineered T cell or engineered pluripotent stem cells with reduced expression, activity, and/or signaling of NKG2A. The obtained engineered T cell and a composition containing the engineered T cell can be used to treat diseases, such as cancer (tumor) and autoimmune diseases.
