Peripheral blood activated B cells (CD27 high CD38 high ) were isolated and sorted by FACS for single cell sequencing. a) Percentage of CD27 high CD38 high cells among live B cells. Each sample is represented by a circle. The line indicates the median. Unpaired two sided Mann-Whitney U test. b) UMAP representation of 72277 CD27 high CD38 high sorted B cells from 9 COVID-19 ICU patients and 3 healthy controls. Between 2416 and 11229 cells were recovered per sample. Transcriptionally similar clusters were identified using shared nearest neighbor (SNN) modularity optimization (left). The combination of <t>CD19,</t> MS4A1, CD27, CD38, IFIT1, MIKI67, IRF4 and PRDM1 expression were used for annotation of the different activation/differentiation stages (right). c) Heatmap of genes that resemble markers for the six different clusters. Depicted are genes with a p-value < 0.01 (Wilcoxon rank sum test) after bonferroni correction, and an average absolute fold-change > log2(1.3). Shown are z-scores of the average expression. d) UMAP representation of the expression levels of selected signature genes for activated/differentiated B cells. e) UMAP representation of analyzed cells from one healthy control and two ICU patients, representing early (first week, patient #1) and late (>7days, patient #5) phase after ICU admission. f) Percentage of cells belonging to a defined cluster among all sequenced B cells per donor. Each dot represents one time point from one single donor. Donors were grouped as “HC” for healthy controls (n = 3), “1st week” for patients within 7 days after ICU admission (n = 6) and “Late” for patients who have been admitted to the ICU for more than a week at the time of analysis (n = 8). The line indicates the median. Significance was determined by using a two-sided analysis of varience (ANOVA) folowed by Tukey’s multiple comparison test with corrected p values as indicated in the figure.

The recovery rates of spiked cell lines were 91.5% for H358 and 84.3% for A549. HDB, healthy donor blood; MCA, Micro Cavity Array.

Article Snippet: To generate this leukocyte-poor fraction, we incubated peripheral blood samples with StraightFrom Whole Blood CD45 MicroBeads at 50 μL per mL of blood passed through a magnetic column (Miltenyi Biotec) before enrichment by the MCA system.

Techniques: Immunofluorescence, Staining

Image of CD45 depletion. (A) Shows an MCA cartridge imaged by immunofluorescence where the leukocytes were depleted using CD45 Microbeads prior to enrichment. (B) Shows high levels of co-eluting leukocytes in an MCA cartridge without pre-treatment with CD45 microbeads. MCA, Micro Cavity Array.
