The present invention relates to CX3CR1-binding polypeptides, in particular polypeptides comprising specific immunoglobulin domains. The invention also relates to nucleic acids encoding such polypeptides; to methods for preparing such polypeptides; to host cells expressing or capable of expressing such polypeptides; to compositions comprising such polypeptides; and to uses of such polypeptides or such compositions, in particular for prophylactic, therapeutic and diagnostic purposes.

The present invention provides antibodies and related molecules that bind to chemokine receptor 4 (CXCR4). The invention further provides antibody-drug conjugates comprising such antibodies, antibody encoding nucleic acids, and methods of obtaining such antibodies. The invention further relates to therapeutic methods for use of these antibodies and anti-CXCR4 antibody-drug conjugates for the treatment of a disorder associated with CXCR4 function or expression (e.g., cancer), such as colon, RCC, esophageal, gastric, head and neck, lung, ovarian, pancreatic cancer or hematological cancers.

Embodiments relate to a modified cell comprising an antigen binding molecule, and the expression and/or function of one or more genes in the modified cell has been enhanced or reduced or eliminated. The one or more genes include CXCR3, SLC1A3, YAP, TIGIT, S1P1, and IL-35. In embodiments, the cell is a T cell, a dendritic cell, a NK cell, or a macrophage cell. In embodiments, the antigen binding molecule comprises a chimeric antigen receptor (CAR) and/or the second antigen binding molecule is a T Cell Receptor (TCR).

Fc-fusion protein derivatives against HIV have enhanced yield in mammalian cells, and extended antiviral and immunomodulatory activities. The Fc-fusion protein derivatives can block the entry of human immunodeficiency virus (HIV) into host cells, elicit effector functions through the activation of natural killer (NK) and other immune system cells, can be produced with high yield in mammalian cells, and have extended activity in vivo. Nucleic acids, vectors and host cells can express the Fc-fusion protein derivatives, which have therapeutic and diagnostic applications in human health.

The present disclosure provides use of chemokine receptor CXCR5, wherein CAR-T cells with enhanced chemotaxis are obtained by modifying chimeric antigen receptor T cells (CAR-T cells) utilizing the chemotactic signal between CXCR5 and its ligand CXCL13. The chemokine receptor CXCR5 can guide CAR-T cells to migrate to tumors. It has an excellent ability to enhance the chemotaxis of CAR-T cells, can specifically clear tumor cells, and effectively solve the problem of poor efficacy of the existing CAR-T therapy for solid tumors, thereby exhibiting broad application prospects and great market value.

Provided is an antibody that specifically recognizes IL-13RA2, which can be used in the manufacture of a targeting anti-tumor medicament as well as a medicament for diagnosing a tumor.

This disclosure relates to the fields of cell biology and the modulation of cell signaling associated with migration and localization of immune cells and aberrant cellular proliferation, migration, and malignancy. Also disclosed are peptides effective in modulating stem cell mobilization, treating cancer, enhancing chemotherapy or immunotherapy, treating genetic disorders, and as immunomodulatory agents. Also disclosed are peptides effective in the treatment of fibrotic diseases. The present disclosure also provides peptides and peptide analogs and the use thereof in methods of treating diseases relating to CXCR4.

The present invention aims to solve a problem in T-cell transfer therapy and the like, which is T-cell exhaustion, and to provide a technique to enhance T cell activity. T cells having cell surface markers of CD45RA.sup.+ and CCR7.sup.+ can be produced by culturing activated T cells in the presence of (a) a conditioned medium derived from stromal cells or (b) CXCL12.

The present invention relates to engineered extra-cellular vesicle internalizing receptors that have the ability to enhance uptake, processing, and presentation to T-cells of tumor-associated antigens by an antigen-presenting cell. It further relates to vectors or antigen presenting cells expressing said receptors, composition and uses thereof for the prevention and/or treatment of a cancer.

Genetically modified compositions, such as non-viral vectors and T cells, for treating cancer are disclosed. Also disclosed are the methods of making and using the genetically modified compositions in treating cancer.
