Decades of work highlighted estrogen as a key hormonal controller of social behaviors, exerting its influence primarily through binding to estrogen receptor alpha (Esr1). Recent technological advances in chemogenetics, optogenetics, gene editing, and transgenic model organisms have allowed for a detailed understanding of the neuronal subpopulations and circuits for estrogen action across Esr1-expressing interconnected brain regions. Focusing on rodent studies, in this review we examine classical and contemporary research demonstrating the multifaceted role of estrogen and Esr1 in regulating social behaviors in a sex-specific and context-dependent manner. We highlight gaps in knowledge, particularly a missing link in the molecular cascade that allows estrogen to exert such a diverse behavioral repertoire through the coordination of gene expression changes. Understanding the molecular and cellular basis of Esr1's action in social behaviors provides insights into the broader mechanisms of hormone-driven behavior modulation across the lifespan.</p>","PeriodicalId":8008,"journal":{"name":"Annual review of neuroscience","volume":" ","pages":""},"PeriodicalIF":12.1,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143472069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The compartmentalization of synaptic vesicles, as well as vesicle releasing and recycling machineries, allows neurotransmitters to be released with precisely controlled timing, speed, and amplitude. The compartmentalized and clustered organization of neurotransmitter receptors and their downstream signaling enzymes allows neuronal signals to be properly received and amplified. Synaptic adhesion molecules also form clustered assemblies to align pre- and postsynaptic subcompartments for synaptic formation, stability, and transmission. Recent studies indicate that such synaptic and subsynaptic compartmentalized organizations are formed via phase separation. This review discusses how such condensed subsynaptic compartments may form and function in the context of synapse formation and plasticity. We discuss how phase separation allows for the formation of multiple distinct condensates on both sides of a synapse and how such condensates communicate with each other.
