An example is production of certain molecules called cytokines by T-cells that activate themselves.
细胞能分泌这类叫做细胞因子的分子,实现自激活
One is shown at the top here, its call autocrine.
一种在最上面,称为自分泌
Here, what's different between autocrine and paracrine is that there's some distance between the cell that produces the signal and the cell that receives the signal, but it's not too great a distance because the blood system doesn't have to be involved.
自分泌和旁分泌的区别在于,旁分泌中,产生信号的细胞和接收信号的细胞,之间存在着一定的距离,但这个距离并不远,因为血液系统并不参与
