Background
IL-5, also named B-cell differentiation factor I, eosinophil differentiation factor and TRF, is belonging to the cytokine family and the IL-5 gene is in close proximity to the genes encoding IL-3, IL-4, and granulocyte-macrophage colony-stimulating factor (GM-CSF), which are often co-expressed in TH2 cells. Through binding to the IL-5 receptor, IL-5 stimulates B cell growth and increases immunroglobulin secretion. It is also a key mediator in eosinophil activation. Interleukin-5 has long been associated with the cause of several allergic diseases including allergic rhinitis and asthma. The cDNA for murine IL-5 encodes a signal peptide and a 113 amino acid mature protein. Mature murine IL-5 shares 70 %, 94 %, 58 %, 66 %, 59 % and 63 % a.a. sequence identity with human, rat, canine, equine, feline and porcine IL5, respectively. It shows cross-reactivity with human IL5 receptor.
