Single-Cell Immune Profiling

Explore the immune system at single-cell resolution

The immune system is a complex, vital network that includes various organs, cell types, and molecules. Two important components of this complex network are the T- and B-cells with their corresponding T-cell receptors (TCRs) and B-cell receptors (BCRs). BCRs recognize antigens leading to activation and subsequent antibody secretion of the cells. TCRs recognize antigens presented by other cells and, therefore, play a vital role in discriminating pathogenic antigens from host antigens. Due to the somatic rearrangement of the B- and T-cell receptor genes, which is also known as V/D/J recombination, a vast number of unique receptors for the detection of various antigens is build. This V/D/J recombination results in an individual’s TCR and BCR repertoire.

Investigating the diversity of immune cells with respect to the TCR and BCR repertoires provides insights into the functioning of our immune system and its response to different conditions. Thus, studies at single-cell resolution using RNA sequencing allow the identification of different clonotypes and clone-specific gene expression. Since a functioning immune system is essential for our health, insights are of high relevance and a better understanding of the immune system composition can help to better understand the complexity of diseases and to develop and test appropriate therapies or vaccines.

Application areas of single-cell immune profiling:

  • Response to different conditions and therapeutic interventions
  • Vaccination and therapy development
  • Target specificity of different clonotypes
  • Investigation of autoimmune diseases

We help you to explore your samples’ immune cell diversity by providing Single-Cell Immune Profiling (SIP).

Bioinformatics

Raw sequencing data are automatically processed. We offer different levels of bioinformatic analysis. The default level is Level 1. With increasing bioinformatic level, more data are delivered. All higher levels include the data from the lower levels. In addition to the data, and independent of the analysis level, a project report is generated.

We analyze your Single-Cell Immune Profiling data with the Cell Ranger software from 10x Genomics®. This workflow includes read alignment, filtering, gene expression analysis, and clonotype calling on the V/D/J libraries.

Level 1:

  • Demultiplexing of the sequencing data, including index reads (FASTQ format)

Level 2:

  • Mapping of the sequencing data
  • Gene expression analysis
  • V/D/J analysis

Level 3:

  • For more than one sequenced sample, your Single-Cell Immune Profiling data is combined into an experiment-wide matrix and reanalyzed after normalization.

Technical Information

We can process between 500 – 10,000 cells per sample, and up to 8 samples can be run in parallel on one Chromium Next GEM Chip. The immune-specific regions of the α- and β- chains (TCR) and Ig-chains (BCR) are preserved and provided as paired sequences. It is recommended to sequence at least 20,000 paired-end reads per cell for the gene expression. For the TCR and BCR libraries, at least 5,000 paired-end reads per cell are recommended. The required sequencing depth strongly depends on the sample type and on the experimental question.

At CeGaT, sequencing is performed using the Illumina sequencing platforms. If you require other sequencing parameters, please let us know! We can provide further solutions.
