白介素19(IL-19)是细胞因子IL-10家族的成员[1]。IL-10家族是细胞因子的第二类α-螺旋集合,包含两个组,一个是病毒同源物,一个是细胞同源物。在细胞同源基因组中,有两个额外的组,一个使用IL-10R2作为信号转导受体(IL-10、IL-22和IL-26),另一个使用IL-20R2作为信号转导受体(IL-19、IL-20和IL-24)[2-4]。小鼠IL-19被合成为一个176个氨基酸(AA)的前体,它包含一个24个氨基酸的信号序列和一个152个氨基酸的成熟区[5]。根据人体研究,它有望以糖基化单体的形式分泌,大小为35-45 kDa[2, 6, 7]。IL-19的不同寻常之处在于它含有七个两亲性螺旋[2, 4, 8]。成熟的小鼠IL-19与成熟的人IL-19的氨基酸序列同源性为69%,与未发表的大鼠和犬IL-19的Genbank序列的同源性分别为85%和68%。虽然小鼠IL-19在人类细胞上是活性的,但人IL-19在小鼠细胞上不是活性的[5]。IL-19的表达仅限于激活的角质形成细胞和单核细胞,可能来自B细胞[6, 9, 10]。IL-19结合由IL-20受体α(也称为IL-20 R1)和IL-20受体β(IL-20 R2)组成的受体复合体[3, 4, 11, 12]。这种受体复合体也被IL-20和IL-24所共享。值得注意的是,据报道,IL-19实际上与IL-20R2结合,后者通常被认为只是信号转导受体亚单位[7, 13]。据报道,在功能上,IL-19可以也不会诱导单核细胞产生IL-6和肿瘤坏死因子[5, 14]。然而,它似乎确实推动T辅助细胞分化为Th2反应,诱导IL-10和自身产生[5, 14]。
