General description

The antibody neutralizes the biological activity of recombinant human IL-5.

Immunogen

recombinant human IL expressed in Sf 21 insect cell line.

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.

Physical form

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline.

Preparation Note

Purified using protein G.

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

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.

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
Patricia C Fulkerson et al.

Eosinophils originate in the bone marrow from an eosinophil lineage-committed, IL-5Rα-positive, hematopoietic progenitor (eosinophil progenitor). Indeed, IL-5 is recognized as a critical regulator of eosinophilia and has effects on eosinophil progenitors, eosinophil precursors, and mature eosinophils. However, substantial levels of

We sought to develop an IL-33 vaccine and evaluate its efficacy in a mouse model of asthma. The full-length molecules of putative mature IL-33 were inserted into the immunodominant epitope region of hepatitis B core antigen using gene recombination techniques.
