受到免疫攻击的雌性脊椎动物会将特定的抗体传递给它们的后代,但是这种无偿的免疫力不能在无脊椎动物中发挥作用。在这里,我们表明,组成性免疫防御增强的大黄蜂熊蜂terrestrisL的有性后代。当亲本群体受到免疫挑战时。我们的研究结果表明,无脊椎动物可能使用免疫系统的不同组成部分,以产生一个兼性的跨代增加免疫反应。
Immune-challenged vertebrate females transfer specific antibodies to their offspring,,, but this gratuitous immunity cannot operate in invertebrates. Here we show that constitutive immune defence is enhanced in sexual offspring of the bumble-beeBombus terrestrisL. when the parental colony is immune-challenged. Our findings indicate that invertebrates may use a different component of the immune system to generate a facultative trans-generational increase in the immune response.
