概述

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.Rat IL-5 is a 132-amino acid(115 in human,133 in the mouse)-long TH2 cytokine that is part of the hematopoietic family.Unlike other members of this cytokine family(namely IL-3 and GM-CSF),this glycoprotein in its active form is a homodimer.
