摘要
目的:观察高甘油三酯(triglyce ride,TG)血对体内及体外血小板CD40L表达的影响及非诺贝特的作用。方法:以TG正常的健康对象为对照,通过流式细胞仪及ELISA法检测高TG患者服用非诺贝特前后血小板膜CD40L表达阳性率及血浆sCD40L表达;然后通过高TG血浆体外孵育健康血小板并用过氧化物酶体增殖活化受体α(PPARα)激动剂WY14643干预,流式细胞仪及Westen blotting法检测血小板膜CD40L表达阳性率及血小板总CD40L蛋白含量。结果:高TG患者CD40L及sCD40L表达显著升高(2.65±0.75vs1.53±0.66,3.72±0.94vs2.27±0.72),服用非诺贝特1个月后随TG浓度降低,血小板膜CD40L表达阳性率及血浆sCD40L浓度均有不同程度降低(1.89±0.56vs2.65±0.75,2.85±0.74vs3.72±0.94);体外高TG血浆较TG正常血浆更能促进血小板膜CD40L的表达(2.81±0.48vs1.89±0.41),且血小板总CD40L蛋白含量也一定程度升高(1.79±0.13vs1.51±0.15,P<0.05);但WY14643对体外血小板膜CD40L表达阳性率及CD40L含量均无显著影响。结论:高浓度的TG血浆体内体外均能够促进血小板CD40L的表达;PPARα激动剂非诺贝特在降低体内TG浓度的同时,也抑制了血小板CD40L的表达;但PPARα激动剂Wy14643体外无直接改变血小板CD40L表达的作用。
