Other Expression profiling by high throughput sequencing
Summary
The relationship of SARS-CoV-2 lung infection and severity of pulmonary disease is not fully understood. We analyzed specimens from 24 autopsies from patients who succumbed to SARS-CoV-2 infection using a combination of different RNA and protein analytical platforms to characterize inter- and intra- patient heterogeneity of pulmonary virus infection. There was a spectrum of high and low virus cases that was associated with duration of disease and activation of interferon pathway genes. Using a digital spatial profiling platform, the intra-pulmonary spatial heterogeneity of the virus corresponded to focal expression of interferon response genes and association with immune checkpoint genes In this dataset, we capture the GeoMx DSP RNA profiling work done in conjunction with this study. The files here represent SARS-CoV-2 infected rapid autopsy patients (n = 6) which were profiled with the NanoString GeoMx COVID19 Atlas RNA panel v1.0. This panel was then read out using Illumina sequencing following standard library preparation according to manufacturer protocols. Attached below are low-resolution images of each slide with placement of all ROIs, as well as individual images of each ROI, segments, and UV illuminated IF channels. For access to high resolution (single channel, composite, or ROI) images please contact GeoMxSupport@nanostring.com or the corresponding author of the study. RNA sequencing data and results for bulk RNA profiling can be accessed in study GSE150316.
Overall design
This dataset contains expression from localized sampling within 6 SARS-CoV-2 infected patient FFPE samples collected during rapid autopsy, with 3 non-infected control samples. Up to 48 segments were collected within each patient sample. RNA Scope on serial sections was used to guide ROI selection, and ROI ISH staining by RNA Scope is noted in the sample annotations.
