Recombinant Anti-CD274 Vesicular Antibody, EV Displayed (VS-0425-YC608)

CAT#: VS-0425-YC608

The Recombinant Anti-CD274 Vesicular Antibody, EV Displayed (VS-0425-YC608) is an antibody-displaying extracellular vesicle (Ab-EV). The product combines the benefits of both extracellular vesicle (EV) and antibody (Ab) which can guide the decorated EVs to CD274-expressed cells or tissues. CD274 is an immune inhibitory receptor ligand interacting with its receptor to inhibit T-cell activation. This interaction prevents autoimmunity but enables tumor immune escape.

  • Introduction
  • This gene encodes an immune inhibitory receptor ligand that is expressed by hematopoietic and non-hematopoietic cells, such as T cells and B cells and various types of tumor cells. The encoded protein is a type I transmembrane protein that has immunoglobulin V-like and C-like domains. Interaction of this ligand with its receptor inhibits T-cell activation and cytokine production. During infection or inflammation of normal tissue, this interaction is important for preventing autoimmunity by maintaining homeostasis of the immune response. In tumor microenvironments, this interaction provides an immune escape for tumor cells through cytotoxic T-cell inactivation. Expression of this gene in tumor cells is considered to be prognostic in many types of human malignancies, including colon cancer and renal cell carcinoma.
