AI Article Synopsis
- Saliva is a complex fluid from various glands in the mouth, and its flow and composition can change based on location and time.
- Researchers used an easy collection method and advanced metabolomic profiling to study how saliva components vary across different areas of the mouth and throughout the day.
- The findings reveal unique metabolite profiles and patterns in saliva, contributing to a better understanding of its complex role in both oral health and overall body functions.
Article Abstract
Saliva is a complex bodily fluid composed of secretions by major and minor salivary glands. Salivary glands and their secretions are known to be unevenly distributed in the human oral cavity. Moreover, saliva flow rate and composition vary across locations and time of the day. This remarkable heterogeneity of salivary secretions suggests that different subtypes of saliva fulfill different functions. By coupling a non-invasive and facile collection method with comprehensive metabolomic profiling, we investigated the spatial and temporal distributions of salivary components. We identified location-specific metabolite profiles, novel oscillating metabolites, and location-specific diurnal patterns. In summary, our study paves the way for a deeper and more comprehensive understanding of the complex dynamics and functionalities of the salivary metabolome and its integration in multi-omics studies related to oral and systemic (patho-)physiology.
