Abstract
Prolactin (PRL) is a 23-kDa protein synthesized and secreted by lactotroph cells of the anterior pituitary gland but also by other peripheral tissues. PRL binds directly to a unique transmembrane receptor (PRLR), and the JAK2/signal transducer and activator of transcription 5 (Stat5) pathway is considered the major downstream pathway for PRLR signaling. To a lesser extent, PRL may be cleaved into the shorter 16-kDa PRL, also called vasoinhibin, whose signaling is not fully known. According to rodent models of PRL signaling inactivation and the identification of human genetic alterations in PRL signaling, a growing number of biological processes are partly mediated by PRL or its downstream effectors. In this review, we focused on PRL structure and signaling and its canonical function in reproduction. In addition to regulating reproductive functions, PRL also plays a role in behavior, notably in initiating nurturing and maternal behavior. We also included recent insights into PRL function in several fields, including migraines, metabolic homeostasis, inflammatory and autoimmune disease, and cancer. Despite the complexity of understanding the many functions of PRL, new research in this field offers interesting perspectives on physiological and pathophysiological processes.
期刊介绍:
Reviews in Endocrine and Metabolic Disorders is an international journal dedicated to the field of endocrinology and metabolism. It aims to provide the latest advancements in this rapidly advancing field to students, clinicians, and researchers. Unlike other journals, each quarterly issue of this review journal focuses on a specific topic and features ten to twelve articles written by world leaders in the field. These articles provide brief overviews of the latest developments, offering insights into both the basic aspects of the disease and its clinical implications. This format allows individuals in all areas of the field, including students, academic clinicians, and practicing clinicians, to understand the disease process and apply their knowledge to their specific areas of interest. The journal also includes selected readings and other essential references to encourage further in-depth exploration of specific topics.
