Description:
Interleukin-5 (IL-5) is a hematopoietic growth factor expressed in Th2, mast cells and
eosinophils. IL-5 acts through its receptor, the IL-5 receptor (IL-5R) and is involved in B
cell growth and eosinophil activation. IL-5 has been shown to be and is regulated by
GATA-3, in addition to other transcription factors. Human and mouse IL-5 are crossreactive.
