Samples were compared using paired t-test (c) or two-sided Wilcoxon test (f). control_subset <- RunPCA(control_subset, npcs = 30, verbose = FALSE) to In h, a two-sided Wilcoxon rank sum test was used, and P values corrected by Bonferroni correction. We would all appreciate it if @timoast or others from the @satijalab can chime in. Results were filtered for gene sets that were significantly enriched with adjusted P<0.05. 36, 421427 (2018). To subset the Seurat object, the SubsetData() function can be easily used. Ritchie, M. E. et al. Then we use FindMarkers() to find the genes that are different between stimulated and control B cells. I want to know: S+ Bm cells continued to show lower but still significantly increased proliferation at month 6, and only returned to background levels at month 12 post-infection (Fig. Yang, R. et al. c, Frequencies of RBD+ Bm cells are provided at indicated days post-symptom onset (left), with lines connecting samples of same individual. Analysis of SARS-CoV-2-specific GC Bcl-6+Ki-67+ B cells detected a trend towards elevated frequencies of S+ and N+ GC cells in recovered compared with vaccinated subjects (Extended Data Fig. 7ac). The pro of this approach is that it is fast and easy. ISSN 1529-2916 (online) The scRNA-seq data showed that SHM counts in SWT+ Bm cells strongly increased from week 2 post-second (median 3) to month 6 post-second dose (median 13) and even further at week 2 post-third dose (median 14) (Extended Data Fig. Hi all, I'm also interested in this issue, and wonder what is the best way to subset and reclustering data starting from an integrating dataset? I have 6 scRNAseq runs of mixed immune cells, I subsetted all T cells (ie. ## [31] xfun_0.37 dplyr_1.1.0 crayon_1.5.2 1c and Supplementary Table 4). 33,34) (Fig. b. it makes no sense to me the not to use the integrated assay on every downstream analysis. 1b and Supplementary Table 3). Downstream analysis was conducted in R version 4.1.0 mainly with the package Seurat (v4.1.1) (ref. g, Comparison of somatic hypermutation (SHM) counts are provided in SWT+ Bm cells at indicated timepoints (week 2 post-second dose, n=174 cells; month 6 post-second dose, n=271 cells; week 2 post-third dose, n=698 cells). Samples in b were compared using a KruskalWallis test with Dunns multiple comparison correction, in ce with a two-tailed Wilcoxon matched-pairs signed-rank test and in i with a two-sided Wilcoxon test with Holm multiple comparison correction.

Gene set variation analysis with the package gsva (v1.42.0) was used to estimate gene set enrichments for more than two groups61. a, Heatmap compares V heavy (VH; left) and VL (right) gene usage in indicated S+ Bm cell subsets and S Bm cells (non-binders) from scRNA-seq data of SARS-CoV-2-infected patients at months 6 and 12 post-infection. Long-lived plasma cells can continuously secrete high-affinity antibodies that are protective against a homologous pathogen7, whereas Bm cells encode a broader repertoire which allows protection against variants of the initial pathogen after restimulation8. So I have a couple of questions regarding my workflow: For downstream DE analysis, the scale.data slot in the SCT assay has disappeared after integration. how to make a subset of cells expressing certain gene in seurat R 4e). Collectively, these data identify a durable, IgG1-dominated S+ Bm cell response forming upon SARS-CoV-2 infection. d, Shown are representative histograms of Ki-67 in patient CoV-P2 (left) and violin plots of percentages of Ki-67+ S+ Bm cells compared with S Bm cells (right) at indicated timepoints.

I integrated samples across multiple batch conditions and diets after performing SCTransform (according to your most recent vignette for integration with SCTransform - Compiled: 2019-07-16). How can I find help page about "%in%"? Of these individuals, 35 received one or two doses of SARS-CoV-2 mRNA vaccination between month 6 and month 12, and three subjects were vaccinated between acute infection and month 6 (Supplementary Table 1 and Extended Data Fig. As you can see, many of the same genes are upregulated in both of these cell types and likely represent a conserved interferon response pathway. I am running comparative analysis between two conditions and would like to identify DEGs between two clusters across these conditions (i.e. When comparing dataset quality, we noticed a markedly lower median gene detection and unique molecular identifier count per cell in one of our datasets of the SARS-CoV-2 Infection Cohort. Biotechnol. Haga, C. L., Ehrhardt, G. R. A., Boohaker, R. J., Davis, R. S. & Cooper, M. D. Fc receptor-like 5 inhibits B cell activation via SHP-1 tyrosine phosphatase recruitment.

The DotPlot() function with the split.by parameter can be useful for viewing conserved cell type markers across conditions, showing both the expression level and the percentage of cells in a cluster expressing any given gene. The scRNA-seq dataset identified a significantly increased SHM count in S+ Bm cells at month 12 compared with month 6 post-infection (Fig. ## [109] vctrs_0.5.2 mutoss_0.1-12 pillar_1.8.1 CD69 expression is a hallmark of tissue residency in T cells3 and has been proposed to characterize resident Bm cells in lymphoid and nonlymphoid tissues47,48,49. 2d). Cheers, all look forward to learning more on this when the devs respond. Now I understand that batch variation is a pain in the a** but honestly one has to assume this will occur naturally in a PCR as well. Weisel, F. & Shlomchik, M. Memory B cells of mice and humans. Our work also provides insight into the CD21CD27 Bm cells, which made up a sizeable portion of Bm cells following acute viral infection and vaccination in humans. SARS-CoV-2-specific Bm cells were identified using probes of biotinylated SARS-CoV-2 spike (S) and receptor-binding domain (RBD) protein multimerized with fluorophore-labeled streptavidin (SAV) and characterized using a 28-color spectral flow cytometry panel (Fig. Resulting scores were used to compute fold changes and significance levels for enrichment score comparisons between cell subsets in limma (v3.50.3) (ref. 3a,b). Can be used to downsample the data to a certain Kim, W. et al. d, Stacked bar graphs represent isotype and subtype distribution in scRNA-seq dataset on all B cells (left), all S+ Bm cells (middle) and indicated S+ Bm cell subsets (right). Takes either a list of cells to use as a subset, or a Note that plotting functions now return ggplot2 objects, so you can add themes, titles, and, "2,700 PBMCs clustered using Seurat and viewed\non a two-dimensional tSNE", # Plotting helper functions work with ggplot2-based scatter plots, such as DimPlot, FeaturePlot, CellScatter, and. Numbers indicate percentages of parent population. e, Representative CD69 histograms in S+ Bm cells of patient CoV-T2 (left) and percentages of CD69+ S+ Bm cells (right) in blood and tonsils. During acute infection S+ Bm cells were mainly immunoglobulin (Ig)M+ and IgG+, whereas IgG+ Bm cells predominated (8590%) at months 6 and 12 post-infection (Fig. In this study, we demonstrated that individual clones of SARS-CoV-2-specific Bm cells harbored the capacity to follow phenotypically and functionally different trajectories after antigen reexposure, becoming CD21CD27+, CD21CD27 or CD21+CD27+/ Bm cells. The inclusion of patients with severe COVID-19 will have increased the average age of our cohort, whereas the individuals from which the tonsil samples were obtained were younger on average. Gene expression data and TotalSeq surface proteome data were integrated separately. Identification of resident memory CD8+ T cells with functional specificity for SARS-CoV-2 in unexposed oropharyngeal lymphoid tissue. 15, 149159 (2015). 7e,f). Another useful way to visualize these changes in gene expression is with the split.by option to the FeaturePlot() or VlnPlot() function. The code could only make sense if the data is a square, equal number of rows and columns. The flow cytometry and scRNA-seq subcohort characteristics are presented in Supplementary Tables 1 and 2, respectively. We stained S, RBD, nucleocapsid (for tonsil samples), hemagglutinin (for tonsil samples) or a decoy probe using separate fluorochrome-conjugated SAVs. 128, 45884603 (2018). Nature 602, 148155 (2021).

In summary, the data showed that S+ CD21CD27FcRL5+ Bm cells carried a very distinct transcriptional profile, similar to certain B cells found in autoimmunity. a, Scatter plot comparing binding scores (LIBRA-Score) was determined from scRNA-seq for SWT and RBD binding, with every dot representing a cell. Following subtraction of raw counts of baiting-negative control from those of all other antigen-baiting constructs in every cell, cutoffs for background binding levels were manually determined for every construct by inspection of bimodal distributions of count frequencies across all cells, and all binding counts below thresholds were set to zero and classified as nonbinding. Single-cell trajectories were created with Monocle3 (version 1.2.9) (ref. Functions reduce_dimension(), order_cells() and graph_test() were executed with default parameters. We found that the various S+ Bm cell subsets contained comparable amounts of SHM, suggesting that CD21CD27 Bm cells originated either from the GC or from a GC-derived progenitor Bm cell upon antigen rechallenge. f, Violin plots of percentages of Ki-67+ S+ Bm cells are shown at indicated timepoints. b, N+ (left) and S+ (right) Bm cell frequencies were determined in paired blood and tonsils of SARS-CoV-2-vaccinated (n=8) and SARS-CoV-2-recovered individuals (n=8). Does anyone have an idea how I can automate the subset process? Similar to @amayer21 I am wondering what the best way to approach this is, and why treating a subsetted data set as new is not the correct way to run an integrated analysis pipeline?

These methods first identify cross-dataset pairs of cells that are in a matched biological state (anchors), can be used both to correct for technical differences between datasets (i.e. a) My approach would be to just run FindClusters() with a higher resolution on the whole dataset until the desired subclustering is reached. Seurat is great for scRNAseq analysis and it provides many easy-to-use ggplot2 wrappers for visualization. Note that @timoast from the Seurat team recommended otherwise, although I never seen an explanation why would this not best way to go. Dugan, H. L. et al. analyzed scRNA-seq data. First, we focused on samples from nonvaccinated individuals at acute infection (n=59, day 14 on average after symptom onset), month 6 (n=61, day 202 after symptom onset) and month 12 (n=17, day 374) (Fig. @satijalab, could you please help us? During acute infection S+ CD21CD27+ Bm cells and CD21CD27 Bm cells represented on average 48.1% and 16.4% of total S+ Bm cells, respectively, and they strongly declined at month 6 (6.3% and 5.3%) and month 12 (3.7% and 6.6%) post-infection (Fig. Wang, Z. et al.
