Whereas S+ Bm cells were predominantly resting CD21+ Bm cells at month 6, vaccination strongly induced the appearance of S+ CD21CD27+ and CD21CD27 Bm cells in blood (Fig. Multi-Assay Features With Seurat, you can easily switch between different assays at the single cell level (such as ADT counts from CITE-seq, or integrated/batch-corrected data). & Kaplan, D. E. Hepatitis C viraemia reversibly maintains subset of antigen-specific T-bet+ tissue-like memory B cells. Transcriptomes of individual cells were used as inputs for the gsva() function with default parameters. Here we showed that single severe acute respiratory syndrome coronavirus 2-specific Bm cell clones showed plasticity upon antigen rechallenge in previously exposed individuals. Dugan, H. L. et al. c, Frequency (median interquartile range) of S+ (left) and N+ (right) GC B cells within total B cells are given in tonsils of SARS-CoV-2-vaccinated and in recovered individuals. b, Shown is weighted-nearest neighbor (WNN) UMAP analysis from scRNA-seq analysis of fluorescence-activated cell-sorted B cells from paired tonsil and blood samples (SARS-CoV-2-recovered, n=2; SARS-CoV-2-vaccinated, n=2). Nucleic Acids Res. 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. 3e and Extended Data Fig. d, Contour plots show CD21 and CD27 expression on blood and tonsillar S+ Bm cells of patient CoV-T2 (left) and frequencies of indicated Bm cell subsets (right). Flow cytometry data were analyzed with FlowJo (version 10.8.0), with gating strategies shown in Extended Data Figs. What was the actual cockpit layout and crew of the Mi-24A? All samples were analyzed by flow cytometry and paired month 6 and 12 samples from nine patients also by single-cell RNA sequencing (scRNA-seq). . Nat. USA 104, 97709775 (2007).
