ABSTRACT: Chronic respiratory diseases are a growing burden, and potentially life-threatening condition if left untreated. It is an urgent medical concern that requires proper diagnosis, treatment, and management to prevent serious complications. Analyzing induced sputum is a non-invasive approach for investigating the mechanisms and progression of respiratory diseases. It allows for the collection of sputum samples without disrupting the patient's normal life. By analyzing the proteins and other molecular substances present in the sputum, it can provide valuable insights into the pathological changes and evaluate the effectiveness of treatments for respiratory diseases. In this study, we carried out proteomic analysis of three types of sputum collected from patients with chronic respiratory diseases using three different digestion methods. In comparison, FASP method was found to be more efficient than In-gel digestion and in-solution digestions, yielding the highest number of unique protein identifications. Integrate the proteomic and phosphoproteomic profiling of three types of sputum, it was observed that raw sputum samples exhibited a higher number of unique protein and phosphoprotein identifications. Our study provides valuable insights into the application of proteomics to the analysis of sputum samples, and serves as a useful resource for understanding the potential of this approach in the study of respiratory diseases.

Project description:The upper respiratory tract, organized along the pharyngolaryngeal-to-tracheobronchial axis, is essential for homeostatic functions such as breathing and vocalization. The upper respiratory epithelium is frequently exposed to pollutants and pathogens, making this an area of first-line defense against respiratory injury and infection. The respiratory epithelium is composed of a rich array of specialized cell types, each with unique capabilities in immune defense and injury repair. However, the precise transcriptomic signature and spatial distribution of these cell populations, as well as potential cell subpopulations, have not been well defined. Here, using single cell RNAseq combined with spatial validation, we present a comprehensive atlas of the mouse upper respiratory epithelium. We systematically analyzed our rich RNAseq dataset of the upper respiratory epithelium to reveal 17 cell types, which we further organized into three spatially distinct compartments: the Tmprss11a+ pharyngolaryngeal, the Nkx2-1+ tracheobronchial, and the Dmbt1+ submucosal gland epithelium. We profiled/analyzed the pharyngolaryngeal epithelium, composed of stratified squamous epithelium, and identified distinct regional signatures, including a Keratin gene expression code. In profiling the tracheobronchial epithelium, which is composed of a pseudostratified epithelium-with the exception of the hillock structure-we identified that regional luminal cells, such as club cells and basal cells, show varying gradients of marker expression along the proximal-distal and/or dorsal-ventral axis. Lastly, our analysis of the submucosal gland epithelium, composed of an array of cell types, such as the unique myoepithelial cells, revealed the colorful diversity of between and within cell populations. Our single-cell atlas with spatial validation highlights the distinct transcriptional programs of the upper respiratory epithelium and serves as a valuable resource for future investigations to address how cells behave in homeostasis and pathogenesis.
