Many physiological systems rely on hormones to communicate and time cellular and tissue-level functions. Most endocrine systems are dynamic and governed by complex regulatory systems and/or feedback mechanisms to generate precise patterns and modes of hormone release in order to optimize control of physiological and cellular processes. This Special Issue focuses on hormone release patterns (ultradian, infradian, pulsatile, circadian), with a special emphasis on the hypothalamic-pituitary axis as well as melatonin release, and how these patterns of hormone secretion change during life stages and disease.

社论：激素​​在哺乳动物中的释放方式。

许多生理系统依靠激素来沟通和计时细胞和组织水平的功能。大多数内分泌系统是动态的，并由复杂的调节系统和/或反馈机制控制，以产生精确的激素释放模式和模式，从而优化对生理和细胞过程的控制。本期专刊侧重于激素释放模式（超音波，红外线，搏动，昼夜节律），特别着重于下丘脑-垂体轴和褪黑激素释放，以及这些激素分泌模式在生命阶段和疾病中如何变化。
