General description

Interleukin-3 is a hematopoietic growth factor, which stimulates basophil development and triggers histamine, IL-4 and IL-6 release. It improves monocyte and macrophage activation and phagocytosis, enhances the secretory function of eosinophils. Interleukin-3 promotes endothelial cell proliferation and migration.

Application

Interleukin-3 from mouse has been used for the determination of 5-lipoxygenase product leukotriene C4 (LTC4) formation. It has also been used as a component of RPMI 1640 medium for cell transfection.

Biochem/physiol Actions

Interleukin-3 (IL-3) is a multifunctional protein, originally called colony forming unit-stimulating activity (CFU-SA), and is produced by activated T lymphocytes. IL-3 supports the formation of multilineage colonies in the early development of multipotent hematopoietic progenitor cells. IL-3 has been shown to induce colony formation of macrophages, neutrophils, mast cells, and megakaryocytes from agar-suspended bone marrow cells. IL-3 also interacts with IL-2 to stimulate growth of T lymphocytes and to induce IgG secretion from activated B cells. Other synonyms for IL-3 include pan-specific hemopoietin, multicolony stimulating factor, mast cell growth factor, burst promoting activity, histamine-producing cell stimulating factor, P cell stimulating factor, and WEHI-3 factor.

Physical form

Lyophilized with 0.5 mg of bovine serum albumin. Sterile filtered through a 0.2 μm filter.

Analysis Note

The biological activity is measured by the dose-dependent stimulation of the proliferation of mouse M-NFS-60 cells.

Signal transducers and activators of transcription (STAT) 1 and STAT3 are activated by overlapping but distinct sets of cytokines. STATs are recruited to the different cytokine receptors through their Src homology (SH) 2 domains that make highly specific interactions with

Basophils, a rare leukocyte population in peripheral circulation, are conventionally identified as CD45(int) CD49b(+) FcεRI(+) cells. Here, we show that basophils from blood and several organs of naïve wild-type mice express CD41, the α subunit of α(IIb)β₃ integrin. CD41 expression

The Interleukins comprise a disparate group of cytokines and growth factors that are produced by and released from leukocytes. Interleukin-1β (1L-1β) is released primarily from stimulated macrophages and monocytes and plays a key role in inflammatory and immune responses and may induce anti-tumor immunity.
