外源性1-磷酸鞘氨醇(S1P)与溶血磷脂酸(LPA)一样,可诱导分化的PC12细胞突起回缩或细胞变圆。溶鞘糖脂诱导的形状改变在低至1 nM时就能被检测到;然而,直到施加1微米的S1P才能检测到细胞内S1P的显著积聚。此外,尽管外源性鞘氨醇通过鞘氨醇激酶催化的磷酸化导致细胞内S1P显著增加,但对形状变化的影响微乎其微。将细胞暴露在固定化的S1P中,其中脂质共价连接到玻璃载体上,也导致了形状的变化。这些结果表明,外源性S1P诱导的形状变化不需要细胞摄取脂肪,但可能需要与神经细胞中的细胞表面受体相互作用。
Exogenous sphingosine 1-phosphate (S1P), like lysophosphatidic acid (LPA), induced neurite retraction or cell rounding in differentiated PC12 cells. The lysosphingolipid-induced shape change was detected at as low as 1 nM; however, a significant accumulation of intracellular S1P was not detected until 1 microM S1P was applied. Moreover, although exogenous sphingosine caused a significant increase in intracellular S1P by sphingosine kinase-catalyzed phosphorylation, the effect on the shape change was marginal. Exposure of the cells to the immobilized S1P in which the lipid was covalently linked to a glass carrier also resulted in the shape change. These results suggest that the exogenous S1P-induced shape change does not require uptake of the lipid into the cells but possibly requires interaction with a cell surface receptor in the neuronal cells.
