摘要 目的通过检测体外培养平滑肌细胞(SMCs)感染人类巨细胞病毒(HCMV)后即刻早期(IE)基因及晚期(L)基因的表达与调控,探讨HCMV感染致动脉粥样硬化(AS)的可能机制。方法应用PCR方法,在SMCs感染HCMV后不同时相点,检测IE基因、L基因的DNA,同时应用反义寡核苷酸及丙氧鸟苷作用于感染细胞,动态观测其对IE基因、L基因的抑制作用。结果 感染细胞12 h即可检测到IE基因,24 h可同时检测到IE基因和L基因,48和72 h只能检测到L基因。丙氧鸟苷作用后,IE基因和L基因相对减弱。而反义硫代寡核苷酸(ASON)作用后,IE基因明显受到抑制,L基因减弱明显。结论 SMCs感染后IE基因、L基因的表达与调控可能在HCMV致AS的发病机制及其治疗中具有重要意义。
