Biochem/physiol Actions
Interleukin-5 is a T-cell derived cytokine that induces the differentiation of B cells into antibody producing plasma cells. It is a critical differentiation factor for eosinophils and regulates the expression of genes required for cell proliferation, survival and maturation. The cellular functions of IL-5 are mediated by JAK-STAT, Btk and Ras/Raf-ERK signaling pathways. IL-5 is a good molecular target for the treatment of eosinophilic diseases.

While interleukin-5 (IL-5) is initially identified by its ability to support the growth and terminal differentiation of mouse B cells in vitro into antibody-secreting cells, recombinant IL-5 exerts pleiotropic activities on various target cells including B cells, eosinophils, and basophils.
International immunology, 21(12), 1303-1309 (2009-10-13)
IL-5 was originally defined as a T-cell-derived cytokine that triggers activated B cells for terminal differentiation into antibody-secreting plasma cells, at least in mice. Concurrently, IL-5 was recognized as the major maturation and differentiation factor for eosinophils in mice and
Elevated numbers of blood and tissue eosinophils are present in allergic diseases and experimental evidence suggests that eosinophils play an important pathogenic role in these conditions. Regulation of eosinophil maturation, recruitment, and survival is under the control of a small
