通过扩散而作用于邻近细胞的激素传递方式。消化道的有些激素就是以此方式传递的。它与经血液运输的“远距分泌”不同,激素物质通过细胞间隙弥散到邻近细胞,传递局部信息,影响组织细胞的功能活动。这些物质被称为局部体液因素。
细胞可能同时具备内分泌、旁分泌和外分泌方式。
G cells may possess endocrine, paracrine and exocrine functions simultaneously.
然而,外泌体更重要的作用似乎是通过旁分泌机制调控微环境。
However, the more important role of exosome seems to be modulation of microenvironment by paracrine mechanisms.
细胞因子是一类小分子多肽,通过自分泌和旁分泌传递细胞应答。
Cytokines are polypeptides, and mediate cellular responses through autocrine and paracrine.
Another example is called paracrine.
另一类叫做旁分泌
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
