Biochem/physiol Actions

Interleukin-5 exhibits activity on eosinophils, B cells, and thymocytes. Human and mouse IL-5 exhibit homology at the nucleotide and amino acid levels and show species cross-reactivity.

Interleukin-5 is a product of activated T lymphocytes and exhibits activity on eosinophils, B cells and thymocytes. Synonyms or biological activities attributed to IL-5 include: EDF (eosinophil differentiating factor), BCGF-II (B cell growth factor-II), TRF (T cell replacing factor), IgA-EF (IgA enhancing factor) and EO-CSF (eosinophil colony stimulating factor). Natural IL-5 is a 45-50 kDa dimeric glycoprotein, although glycosylation is not required for activity. Human and mouse IL-5 exhibit homology at the nucleotide and amino acid levels and show species cross-reactivity.
