在人工生物膜—脂质体上观察了牛磺酸对Ca~(2+)引起的脂质体聚集的影响。结果表明,牛磺酸对Ca~(2+)引起的脂质体聚集的影响呈双向性,即低Ca~(2+)浓度(5μmol/L)时促进,而高Ca~(2+)浓度(5mmol/L)时抑制脂质体聚集。牛磺酸的上述作用受脂质体内Na~+和K~+浓度的影响。实验结果提示,牛磺酸具有缓冲Ca~(2+)效应的作用,这可能是牛磺酸能有效调节细胞钙稳态的机理之一。 The effect of taurine on Ca 2+ -induced liposome accumulation was observed on artificial biofilm-liposomes. The results showed that taurine had a bidirectional effect on the aggregation of Ca ~ (2 +) - induced liposomes, that is, promoted by low Ca 2+ concentration (5μmol / L) Concentration (5mmol / L) inhibited liposome aggregation. The above effects of taurine are affected by Na ~ + and K ~ + concentrations in liposomes. The experimental results suggest that taurine has a buffering Ca 2+ effect, which may be one of the mechanisms by which taurine can effectively regulate the calcium homeostasis.
