胰岛素对原生动物葡萄糖摄取的影响。

Experientia. 1975 Sep 15;31(9):1097-8. doi: 10.1007/BF02326980.

Insulin stimulates the glucose uptake of Tetrahymena pyriformis. This shows the presence of insulin receptors in Tetrahymena, consequently receptors may be present in a level of phylogenesis, where the natural contact between the given hormone and the cell is unnecessary and impossible.

胰岛素可刺激梨形四膜虫摄取葡萄糖。这表明梨形四膜虫中存在胰岛素受体，因此在系统发育的某个水平上可能存在受体，在这个水平上，特定激素与细胞之间的自然接触既不必要也不可能。
