白介素3（IL-3）是一种多功能蛋白，起初被称为克隆形成单位刺激活性（CFU-SA），由活化的T淋巴细胞产生。IL-3在多能造血祖细胞的早期发育中可支持多谱系克隆的形成。IL-3已显示出可从琼脂悬浮的骨髓细胞诱导巨噬细胞、嗜中性粒细胞、肥大细胞和巨核细胞的克隆形成。IL-3也可与IL-2发生互作，以刺激T淋巴细胞的生长并诱导活化B细胞分泌IgG。IL-3的其他同义词包括泛特异性造血素、多克隆刺激因子、肥大细胞生长因子、爆发促进活性、组胺生成细胞刺激因子、P细胞刺激因子和WEHI-3因子。

Physical form
Lyophilized from a 0.2 μm filtered solution.
Other Notes
One unit is the amount of IL-3 required to induce half-maximal incorportion of 3H thymidine. Activity also is expressed in Reference units (NIBSC reference preparation for IL-3 code 88/87).

Basophils are primarily associated with immunomodulatory functions in allergic diseases and parasitic infections. Recently, it has been demonstrated that both activated human and mouse basophils can form extracellular DNA traps (BETs) containing mitochondrial DNA and granule proteins. In this report

Impaired megakaryocyte maturation and insufficient platelet production have been shown to participate in the pathogenesis of immune thrombocytopenia (ITP). Our previous study demonstrated that low expression of tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) in megakaryocytes contributed to impaired platelet production
