   <abstract xml:lang="ru">
    <p>В человеческих сперматозоидах акросомная реакция и гиперактивация, два важных события оплодотворения, регулируются концентрацией свободных ионов кальция в цитоплазме клетки. Оба данных события могут быть индуцированы стероидным гормоном прогестероном, который опосредованно активирует находящийся в жгутике сперматозоида кальциевый канал CatSper. Сквозь него ионы кальция входят в клетку и диффундируют в шейку сперматозоида, где присутствует изоформа фермента фосфолипазы С PLCδ. Её активность повышается при повышении концентрации ионов кальция; она катализирует производство вторичного мессенджера инозитолтрифосфата из мембранного фосфолипида фосфатидилинозитола 4,5-бисфосфата. Инозитолтрифосфат активирует расположенные на кальциевом депо сперматозоида RNE инозитолтрифосфатные канал-рецепторы, способствуя выходу ионов кальция в цитоплазму.</p>

   <trans-abstract xml:lang="en">
    <p>In human spermatozoa acrosome reaction and hyperactivation, two important fertilization events, are regulated by free calcium ion concentration in cell cytosol. Both of those events can be induced by progesterone, a steroid hormone which indirectly activates CatSper. CatSper is a cation channel located in sperm flagella; calcium ions enter cytosol through the open channel and then diffuse into spermatozoon midpiece, where a specific isoform of phospholipase C, PLCδ, is located. Activity of this enzyme is upregulated by calcium concentration rise; PLCδ catalyzes inositole-1,4,5-triphosphate production from a membrane phospholipid phosphatidylinositol 4,5-bisphosphate. IP3 activates IP3 channel-receptors located on the spermatozoon calcium store, redundant nuclear envelope (RNE), and thus induces calcium release into cell cytoplasm through those receptors.</p>
