生化／生理作用
白介素-4是对免疫活性细胞的生长和分化具有明显的影响的淋巴因子。IL-4又称B细胞刺激因子-1（BSF-1）、T细胞生长因子-2（TCGF-2）和肥大细胞生长因子-2（MCGF-2）。抑制VEGF和bFGF诱导的血管生成。 IL-4是由活化的T细胞亚群释放的复合糖蛋白。人和小鼠 IL-4 具有50％的氨基酸序列同源性，但它们的生物学作用是物种特异性的。

Cellular responses to both physiological and pathological DNA double-strand breaks are initiated through activation of the evolutionarily conserved ataxia telangiectasia mutated (ATM) kinase. Upon DNA damage, an activation mechanism involving autophosphorylation has been reported to allow ATM to phosphorylate downstream
