Non-fucosylated Anti-Human IL-5 (Mepolizumab) Therapeutic Antibody (CAT#: BioBet-018ZP) Datasheet

IL5

interleukin 5

This gene encodes a cytokine that acts as a growth and differentiation factor for both B cells and eosinophils. The encoded cytokine plays a major role in the regulation of eosinophil formation, maturation, recruitment and survival. The increased production of this cytokine may be related to pathogenesis of eosinophil-dependent inflammatory diseases. This cytokine functions by binding to its receptor, which is a heterodimer, whose beta subunit is shared with the receptors for interleukine 3 (IL3) and colony stimulating factor 2 (CSF2/GM-CSF). This gene is located on chromosome 5 within a cytokine gene cluster which includes interleukin 4 (IL4), interleukin 13 (IL13), and CSF2 . This gene, IL4, and IL13 may be regulated coordinately by long-range regulatory elements spread over 120 kilobases on chromosome 5q31

Mepolizumab

Mepolizumab is an immunoglobulin G1κ monoclonal antibody that specifically targets the IL-5 antigen. IL-5 is a transmembrane glycoprotein with many functions and is highly expressed in hematological malignancies, including multiple myeloma tumors. IL-5 can regulate receptor-mediated adhesion, signaling, and cyclase and hydrolase activity. Mepolizumab inhibits tumor cell growth and induces broad-spectrum apoptosis by binding to IL-5 in a variety of mechanisms: Fc-mediated cross-linking, complement-dependent cytotoxicity, antibody-dependent cytotoxicity, and immune-dependent cell phagocytosis Lead tumor cell lysis.
