Review 2: "Impaired local intrinsic immunity to SARS-CoV-2 infection in severe COVID-19"
This preprint uses single cell RNA-seq (scRNA-seq) to reconstruct nasopharyngeal tissue reorganization in COVID-19 patients. Reviewers deemed the manuscript's main claims well-substantiated, carefully qualified, and significantly novel.

BD FACSDivasuggested: (BD FACSDiva Software, RRID:SCR_001456)FlowJosuggested: (FlowJo, RRID:SCR_008520)Data Preprocessing and Quality Control: Pooled libraries were demultiplexed using bcl2fastq (v2.17.1.14) with default settings (mask_short_adapter_reads 10, minimum_trimmed_read_length 10, implemented using Cumulus, snapshot 4, https://cumulus.readthedocs.io/en/stable/bcl2fastq.html)122. bcl2fastqsuggested: (bcl2fastq , RRID:SCR_015058)Libraries were aligned using STAR within the Drop-Seq Computational Protocol (https://github.com/broadinstitute/Drop-seq) and implemented on Cumulus (https://cumulus.readthedocs.io/en/latest/drop_seq.html, snapshot 9, default parameters)121. STARsuggested: (STAR, RRID:SCR_015899)Using cluster annotations previously assigned from iterative clustering in Seurat, cells from epithelial cell types were pre-processed according to the scVelo pipeline: genes were normalized using default parameters (pp.filter_and_normalize), principal components and nearest neighbors in PCA space were calculated (using defaults of 30 PCs, 30 nearest neighbors), and the first and second order moments of nearest neighbors were computed, which are used as inputs into velocity estimates (pp.moments). scVelosuggested: (scVelo, RRID:SCR_018168)Metatranscriptomic Classification of Reads from Single-Cell RNA-Seq: To identify co-detected microbial taxa present in the cell-associated or ambient RNA of nasopharyngeal swabs, we used the Kraken2 software implemented using the Broad Institute viral-ngs pipelines on Terra (https://github.com/broadinstitute/viral-pipelines/tree/master)86. Kraken2suggested: NoneHere, we employed CellBender (https://github.com/broadinstitute/CellBender), a software package built to learn the ambient RNA profile per sample and provide an ambient RNA-corrected output93. CellBendersuggested: NoneDESeq2 was run with default parameters and test = βWaldβ. DESeq2suggested: (DESeq, RRID:SCR_000154)Gene set enrichment analysis (GSEA) was completed using the R package fgsea over genes ranked by average log foldchange expression between each group, including all genes with an average expression > 0.5 UMI within each respective cell type128. Gene set enrichment analysissuggested: (Gene Set Enrichment Analysis, RRID:SCR_003199)Statistical Testing: All statistical tests were implemented either in R (v4.0.2) or Prism (v6) software129. Prismsuggested: (PRISM, RRID:SCR_005375)Data and Code Availability: Prism (v6), R (v4.0.2) packages ggplot2 (v3.3.2130), Seurat (v3.2.2131), ComplexHeatmap (v2.7.3132), Circlize (0.4.11133), fgsea (v.1.16.0128), DESeq2 (v1.30.0126), and Python (v3.8.3) package scVelo (v0.3.077) were used for visualization. ggplot2suggested: (ggplot2, RRID:SCR_014601)ComplexHeatmapsuggested: (ComplexHeatmap, RRID:SCR_017270)Circlizesuggested: (circlize, RRID:SCR_002141)Pythonsuggested: (IPython, RRID:SCR_001658)Results from OddPub: Thank you for sharing your code.
