精子获能和顶体反应是精子最终完成受精过程中两个主要的生理活动,钙离子(Ca2+)作为细胞信号第二信使在其中起着重要的调节作用。现着重从Ca2+的正负调节、内流和清除等方面,综述其在精子获能和顶体反应中的作用机制。
Sperm capacitation and acrosome reaction are the two major physiological activities during the final fertilization of sperm. Calcium (Ca2 +) plays an important regulatory role as the second messenger of cell signaling. The emphasis is on the mechanism of sperm capacitation and acrosome reaction from the aspects of positive and negative regulation, influx and clearance of Ca2 +.
