CD21CD27 Bm cells depend on the transcription factor T-bet for their development30, are CD11chi and express inhibitory coreceptors, such as Fc receptor-like protein 5 (FcRL5) (refs. Thanks for contributing an answer to Stack Overflow! ## [79] mathjaxr_1.6-0 ggridges_0.5.4 evaluate_0.20 8g). cells = NULL, I have been subsetting a cluster from a Seurat object to find subclusters. 40, 413442 (2022). These results suggest that CD21CD27 Bm cells partake in the normal immune response to pathogens37. e, Presented are SHM counts in S+ Bm cells binding SWT, variant S (Sbeta and Sdelta) or RBD at month 6 (n=634 cells) and month 12 post-infection (n=197 cells; nonvaccinated); SHM counts in nave B cells (n=1,462) are shown as reference. d, Representative histograms (left) and violin plots of indicated markers on S+ Bm cell subsets (right) postVac were derived from the flow cytometry dataset (n=37). PubMed Central A. et al. Sign up for the Nature Briefing newsletter what matters in science, free to your inbox daily. 1 Answer Sorted by: 1 With a little bit of workaround: i) Add a new column to the data slot (only because your original subset () call does so but it can be raw counts or any other data matrix in your Seurat object). Here is an example with dummy data: The subset of dat where bf11 equals any of the set 1,2,3 is taken as follows using %in%: As to why your original didn't work, break it down to see the problem. ; and #310030-200669 and #310030-212240 to O.B. Out of all possible solutions, I feel like performing the analysis as @tilofreiwald's "option b" would be the best. Here we plot 2-3 strong marker genes for each of our 14 clusters. Choose a subset of cells, and then split by samples and then re-run the integration steps (select integration features, find anchors and integrate data). I did see batch effects here (cells from different batches did not share clusters). SCT_integrated <- FindNeighbors(SCT_integrated, dims = 1:15) It is unclear whether the CD21CD27 Bm cells observed post-vaccination can again become resting Bm cells or whether this phenotype is terminally fated. | RenameIdent(object = object, old.ident.name = "old.ident", new.ident.name = "new.ident") | RenameIdents(object = object, "old.ident" = "new.ident") | Cells were sorted on a FACS Aria III 4L sorter using the FACS Diva software. and O.B. This scRNA-seq approach detected frequencies of about 30% of RBD+ Bm cells within S+ Bm cells that were comparable to flow cytometry (Extended Data Figs. To obtain 6, eabl9105 (2021). Provided by the Springer Nature SharedIt content-sharing initiative, Nature Immunology (Nat Immunol) A recent question here gets into that particular problem a bit. c, Heat map shows selected, significantly differentially expressed genes in indicated S+ Bm cell subsets. SARS-CoV-2 infection generates tissue-localized immunological memory in humans. The FCRL4hiENTPD1hiTNFRSF13Bhi cluster (cluster 6) probably represented the FcRL4+ B cell subset, and contained very few SWT+ Bm cells (Fig. X-axis shows log-fold change and y-axis the adjusted P values (p<0.05 was considered significant). ), Deutsche Forschungsgemeinschaft (WA 1597/6-1 and WA 1597/7-1 to K.W.

After subsetting clusters of interest (subsetting by ident) I have a Seurat object with RNA, SCT and integrated assay, and dimensional reduction (pca, tsne, umap) coming from the original Seurat object. Takes either a list of cells to use as a subset, or a parameter (for example, a gene), to subset on. ## [109] vctrs_0.5.2 mutoss_0.1-12 pillar_1.8.1 Below, we demonstrate methods for scRNA-seq integration as described in Stuart*, Butler* et al, 2019 to perform a comparative analysis of human immune cells (PBMC) in either a resting or interferon-stimulated state. ## [139] Biobase_2.58.0 numDeriv_2016.8-1.1 shiny_1.7.4. As one can see in the pic below, the quality is quite different in each of the duplicated conditions. 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. Cervia, C. et al. Keller, B. et al. In e, two-sided Wilcoxon test was used with Holm multiple comparison correction. The best answers are voted up and rise to the top, Not the answer you're looking for? *P<0.05, **P<0.01, ***P<0.001, ****P<0.0001. a, Uniform manifold approximation and projection (UMAP) plots of S+ Bm cells are provided during acute SARS-CoV-2 infection and at months 6 and 12, showing samples of nonvaccinated individuals from the SARS-CoV-2 Infection Cohort, subsampled to maximally 25 cells per sample (Acute, n=44; month 6, n=59; month 12, n=17). e, Volcano plot comparing transcript levels in S+ Bm cells is displayed at month 6 versus 12. Here, we take the average expression of both the stimulated and control naive T cells and CD14 monocyte populations and generate the scatter plots, highlighting genes that exhibit dramatic responses to interferon stimulation. d, Venn diagram displays clonal overlap of SARS-CoV-2-specific clones at months 6 and 12 post-infection. Sci. The B cell response to different pathogens uses tailored effector mechanisms and results in functionally specialized memory B (Bm) cell subsets, including CD21+ resting, CD21CD27+ activated and CD21CD27 Bm cells. 8 SARS-CoV-2-specific B. Correspondence to I would also like to know the recommended way of doing this. Subsequently, we analyzed S+ Bm cells in the blood of SARS-CoV-2-nave individuals (all seronegative for S-specific antibodies) by flow cytometry (n=11, five females and six males) and scRNA-seq (n=3) sampled before their SARS-CoV-2 mRNA vaccination, at days 813 (week 2) post-second dose, 6months after the second dose and days 1114 post-third dose (Extended Data Fig. control_subset <- FindNeighbors(control_subset, dims = 1:15) However I did the following: Next I perform FindConservedMarkers on each of the cell clusters to identify conserved gene markers for each cell cluster. Fourteen cycles (in one case 17) of initial cDNA amplification were used for all sample batches, and single-cell sequencing libraries for whole-transcriptome analysis (GEX), BCR profiling (VDJ) and TotalSeq (BioLegend) barcode detection (ADT) were generated. Anti-SARS-CoV-2 antibodies were measured by a commercially available enzyme-linked immunosorbent assay specific for S1 of SARS-CoV-2 (Euroimmun SARS-CoV-2 IgG and IgA)57 or by a bead-based multiplexed immunoassay58. Gene set enrichments for individual cells were summarized to patient pseudobulks by calculating mean enrichment values of cells belonging to the same patient. assay = NULL, # To pull data from an assay that isn't the default, you can specify a key that's linked to an assay for feature pulling. Nat Immunol (2023). Downstream analysis was conducted in R version 4.1.0 mainly with the package Seurat (v4.1.1) (ref. DefaultAssay(control_subset) <- "integrated" These authors contributed equally: Yves Zurbuchen, Jan Michler. Bm cells are colored by cluster (f, left), tissue origin (f, right) or SWT binding (g). Flow cytometry using the multimer probe approach (Extended Data Fig. At this point the tutorial displayed the UMAP plots with DimPlots and went forward to combine additional human PBMC datasets from eight different technologies. Memory lymphocytes are usually long-lived and provide faster and more vigorous immune responses upon secondary contact with their specific antigen2. Germline sequences, inferred by the Immcantation pipeline, are shown in white (squares). I have a seurat object with 10 samples (5 in duplicates). 59). O.B. control_subset <- RunPCA(control_subset, npcs = 30, verbose = FALSE) to c, Stacked bar plots (mean + SD) show isotypes of S+ Bm cells at week 2 (n=10) and month 6 (n=11) post-second dose and at week 2 post-third dose (n=10).

But I especially don't get why this one did not work: c, Stacked bar graphs show single patient contribution to the WNN clusters. Can the game be left in an invalid state if all state-based actions are replaced? Immunity 51, 398410.e5 (2019). IgG1 represented the most common subtype (around 65% of S+ Bm cells at months 6 and 12 post-infection), and between 5% and 10% of S+ Bm cells were IgA+ (Fig. Weisel, F. & Shlomchik, M. Memory B cells of mice and humans. Sample assignment of cells was done using TotalSeq-based cell hashing and Seurats HTODemux() function. Raw counts obtained from the cellranger gene expression matrix were used to create cell datasets, which were preprocessed using the Monocle 3 pipeline. Why did US v. Assange skip the court of appeal? To visualize the two conditions side-by-side, we can use the split.by argument to show each condition colored by cluster. g, Stacked bar graphs show contribution of total Bm cell subsets to Monocle clusters.

To identify canonical cell type marker genes that are conserved across conditions, we provide the FindConservedMarkers() function. Gene set variation and enrichment analysis revealed a strong enrichment of a previously described B cell signature of IgDCD27CXCR5 atypical Bm cells from patients with systemic lupus erythematosus (SLE)36, in our SARS-CoV-2-specific CD21CD27FcRL5+ Bm cell subset (Fig. English version of Russian proverb "The hedgehogs got pricked, cried, but continued to eat the cactus", Effect of a "bad grade" in grad school applications. 6, eabg6916 (2021). Also, instead of changing the default assay to "RNA", finding the variable features, and changing the default assay back to "integrated", would it be make more sense to just delete those lines of code and just change: Primary Handling Editor: Ioana Visan in collaboration with the Nature Immunology team. subset.name = NULL, I just do not want to do manual subsetting on 10 genes, then manually getting @data matrix from each subset, and recreating seurat object afterwards. SubsetData( This issue may help you address your question. Are there any canonical examples of the Prime Directive being broken that aren't shown on screen? '||', where the operator is quoted. designed and performed scRNA-seq experiments, and analyzed and interpreted data. 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. The markers were ordered by hierarchical clustering. 5f,g). Samples in f were compared using two-proportions z-test. Sci. ), A vector of cell names to use as a subset. Just to demonstrate, a more complicated logical subset would be: data (airquality) dat <- subset (airquality, subset = (Temp > 80 & Month > 5) | Ozone < 40) And as Chase points out, %in% would be more efficient in your example: myNewDataFrame <- subset (bigfive, subset = bf11 %in% c (1, 2, 3)) Honestly now I'm very stringent on what my definition of a DE is because minor gene fluctuations in scRNAseq data are very unreliable and reside within the realm of false-positive dropouts. 22,54). 9b). They were also enriched in gene transcripts involved in interferon (IFN)- and BCR signaling and showed high expression of integrins ITGAX, ITGB2 and ITGB7 (Fig. In addition, since I am not integrating the subset, is it recommended to use the "scale.data" slot in the SCT assay for DE analysis or continue using the "data" slot in the SCT assay for this subset? Density plots indicate count distributions across binding score ranges are shown on top and on the side. Profiling B cell immunodominance after SARS-CoV-2 infection reveals antibody evolution to non-neutralizing viral targets.
