Applications

Intracellular BD^® AbSeq Antibody-Oligos can be used to characterize a heterogeneous subset of T follicular helper (T_FH) cells in human tonsil

A combination of intracellular CITE-seq, surface CITE-seq and scRNA-seq was used to deepen our understanding of the differentiation states and subsets of cells present at low abundance, such as T_FH cells.

We characterized the heterogeneous subsets of T_FH and circulating T_FH (cT_FH) cells using a combination of intracellular CITE-seq, surface CITE-seq and whole transcriptome single-cell RNA sequencing (scRNA-seq) analysis. Germinal center and cT_FH cells were enriched by sorting memory CD4⁺, CXCR5⁺, PD-1⁺ from a tonsil (n = 1) and memory CD4⁺ CXCR5⁺ cells from a matched blood sample and a healthy blood donor (n = 2). We examined the expression of Bcl-6 and other transcription factors, using protein and RNA expression data, across pre-T_FH (an early development stage in the germinal center), T_FH and cT_FH cells.

Human Tonsil TFH Characterization Using AbSeq Oligos

Tonsillar T_FH cells were enriched and stained with both surface and intracellular BD^®AbSeq Antibody-Oligos.

B) Statistically significant (Bonferroni adjusted P value (P val adj) > 0.05) versus fold change for differentially expressed genes (DEG) between T_FH cells compared to pre-T_FH cells. C) Heatmap visualizing the gene signatures and surface and intracellular BD^®AbSeq Antibodies used to identify cell subsets within the tonsil. D) Top panels display surface and intracellular BD^®AbSeq Antibodies used to identify T_FH cell (left), T regulatory cells (T_Reg) (middle) and B cells (right). Bottom panels display corresponding RNA signatures. E) Surface and intracellular BD^® AbSeq Antibodies correlate with RNA expression within the tonsil.
