Longitudinal Saliva Omics Responses to Immune Perturbation: A Case Study [saliva small RNA-seq]

ABSTRACT: The investigation includes findings from our clinical trial, monitoring individualized response to pneumococcal vaccination, where we have carried out integrative profiling assessment of saliva pre and post vaccination in a single individual. This is to our knowledge the most extensive saliva-centered omics dataset on an individual, covering 100 timepoints over the course of one year. The time span covers a healthy period as well as comprehensive monitoring of innate and adaptive immune responses following pneumococcal vaccination. Protein and RNA from saliva were produced at each timepoint (100 timepoints), and mass spectrometry proteomics and RNA-sequencing were carried out for all samples in non-targeted comprehensive profiling. Specifically, a single individual (male, 38) was profiled over multiple timepoints during healthy periods, as well as post treatment with pneumococcal vaccine (PPSV23). Initially pre-immunization samples, including a 24 hour period with hourly sampling (samples P1052515H07-P1052615H08), were collected to provide a comparative baseline. A subsequent 24-hour time course was performed, with again hourly samples taken pre and post vaccination (P1060715H07-P1060815H06). The PPSV23 pneumococcal vaccine was admistered inbetween timepoints at approximately 10.30am, prior to datapoint P1060715H11. Following the vaccination, and after the 24 hour monitoring, daily samples were taken for about a month (up to sample P1070715H08), to capture innate and adaptive responses in saliva. Two more weekly samples followed, with then monthly sample till the end of the investigation. Omics sample analysis includes: RNA-sequencing of total RNA, small RNA sequencing in saliva extracellular vesicles and saliva mass spectrometry proteomics. Note on sample naming: The sample identifier/name P1MMDDYYHhh corresponds to: patient index:P1, date MMDDYY and hour hh preceded by H using 24 hour enumeration.

Project description:The investigation includes findings from our clinical trial, monitoring individualized response to pneumococcal vaccination, where we have carried out integrative profiling on peripheral blood mononuclear cells (PBMCs) and saliva pre and post vaccination in a single individual. This is to our knowledge the most extensive saliva-centered omics dataset on an individual, covering 100 timepoints over the course of one year. The time span covers a healthy period as well as comprehensive monitoring of innate and adaptive immune responses following pneumococcal vaccination. Protein and RNA from saliva and PBMCs were produced at each timepoint (100 timepoints for saliva, 25 for PBMCs), and mass spectrometry proteomics and RNA-sequencing were carried out for all samples in non-targeted comprehensive profiling. Specifically, a single individual (male, 38) was profiled over multiple timepoints during healthy periods, as well as post treatment with pneumococcal vaccine (PPSV23).

Two more weekly samples followed, with then monthly sample till the end of the investigation. Concurrently, weekly or monthly PBMC samples were taken. Omics sample analysis includes: RNA-sequencing of total RNA in saliva and PBMCs. small RNA sequencing in saliva. Proteomics in saliva and PBMCs. small RNA from extracellular vesicles in saliva. Note on sample naming: The sample identifier/name P1MMDDYYHhh corresponds to: patient index:P1, date MMDDYY and hour hh preceded by H using 24hour enumeration. Overall the study produced 100 timepoints for saliva in the span of a year, as well as 30 PBMC samples.

This is to our knowledge the most extensive saliva-centered omics dataset on an individual, covering more than 100 timepoints over the course of one year. The time span covers a healthy period as well as comprehensive monitoring of innate and adaptive immune responses following pneumococcal vaccination. Protein and RNA from saliva and PBMCs were extracted at various timepoints (100+ timepoints for saliva, 25 for PBMCs), and mass spectrometry proteomics and RNA-sequencing were carried out for all samples in non-targeted comprehensive profiling. Specifically, a single individual was profiled over multiple timepoints during healthy periods, as well as post treatment with pneumococcal vaccine (PPSV23).

Omics sample analysis includes: RNA-sequencing of total RNA in saliva and PBMCs. small RNA sequencing in saliva. Proteomics in saliva and PBMCs. For the Proteomics, samples were ran in sets of 6 (5 timepoints + common reference from pooled sample sets), using Tandem Mass Tagged (TMT labeling, 6-plex). Note on sample naming: The sample identifier/name P1MMDDYYHhh corresponds to: patient index:P1, date MMDDYY and hour hh preceded by H using 24hour enumeration, based on EST times.
