High-throughput Ig and TCR repertoire single-cell sequencing analysis in rhesus macaques

ABSTRACT: Recent advancements in microfluidics and high-throughput sequencing technologies have enabled recovery of paired heavy- and light- chain of immunoglobulins (Ig) and VDJ- and VJ- chains of T cell receptors (TCR) from thousands of single cells simultaneously. Due to the complexity of these polyclonal receptors, for many species single-cell immune repertoire sequencing assays are not yet commercially available. Rhesus macaques are one of the most well-studied model organisms of the human adaptive immune response; application of these new immune repertoire sequencing assays is highly relevant to vaccine and infectious disease studies. Here we use custom designed primers to target and enrich for every known Ig and TCR chain and isotype in the rhesus macaque animal model. We sequenced more than 110,000 cell barcodes from rhesus macaque repertoires using PBMC, splenocyte, and FACS-sorted T and B cell. We were able to recover every Ig and TCR isotype, measure clonal expansion in proliferating T cells, and pair repertoires with gene expression profiles of single cells. Our results establish the ability to perform single-cell based immune repertoire analysis in rhesus macaque.

Characterizing adjuvants’ effects at the murine immunoglobulin repertoire level

Project description:We developed an improved library prep protocol and standardized the data analysis pipeline for accurate repertoire profiling. In addition, two metrics were implemented to assess repertoire clone properties. We then studied systemically the effects of two adjuvants, CpG and Alum, on the Ig heavy chain repertoire using the ovalbumin (OVA) challenged mouse model. Ig repertoires of different tissues (spleen and bone marrow) and isotypes (IgG and IgM) were examined and compared in terms of sequence mutation frequency, IGHV gene usage, CDR3 length, rescaled Hill numbers for clonal diversity, and clone selection strength. As a result, Ig repertoires of different tissues or isotypes exhibited distinguishable profiles at the non-immunized steady state. Adjuvanted immunizations further resulted in statistically significant alterations in Ig repertoire compared with PBS or OVA alone immunized groups. Lastly, we applied unsupervised machine learning techniques – multiple factor analysis and clustering – to identify Ig repertoire signatures in different compartments and under varying immunizations.

Single-cell TCR sequencing reveals the dynamics of T cell repertoire profiling during Pneumocystis infection

Project description:T cell response exert critical roles in the host adaptive immunity against Pneumocystis. However, the dynamics and diversity of T cell immune repertoire in HIV-negative Pneumocystis remains unknown. In this study, single-cell RNA and T cell receptor (TCR) sequencing were applied on cells sorted from lung tissues of mice infected with Pneumocystis from 0 to 4 weeks. Our data demonstrated clonally CD4+ T cells and CD8+ T cells expanded in response to Pneumocystis, which marked by highly expressed genes associated with T cell activation and cytotoxicity. The length distribution of CDR3 AA and gene usage variability were similar between Pneumocystis infected mice and control group. We tracked the transcriptome and TCR immune repertoires profiles of expanded lymphocyte clones during Pneumocystis infection, which demonstrate a reconstitution of the TCR immune repertoire after Pneumocystis infection.

High throughput sequencing of immunoglobulin (Ig) heavy (IgH) and light (IgL) chain repertoires

Project description:We used 454 sequencing to assess the repertoire of B cell subsets from bone marrow, spleen, and small intestinal lamina propria from two mouse strains. We used a RAG2-GFP reporter mouse strain (129Sve background) to isolate CD19+ RAG2+ B lineage cells from bone marrow and small intestinal lamina propria and total splenic B cells. We used 5' RACE to amplify cDNA libraries using primers specific for the mu constant region of IgH and the Ig kappa constant region. We also used this technique to analyze total B cell libraries from Swiss Webster germ-free mice to compare to littermate controls that were cohoused with regular specific pathogen free (SPF) mice for 7 days. Examination of the Ig kappa repertoire and IgH repertoire in RAG2+ bone marrow B lineage cells compared to RAG2+ small intestinal lamina propria B lineage cells or total splenic B cells. There are 8 (Ig kappa) or 4 (IgH) independent experiments comparing repertoires in RAG2-GFP mice. Each experiment in RAG2-GFP+ mice consisted of a pool of 8-12 mice. There are 3 experiments comparing germ-free to colonized mouse total B cell repertoires, each consisting of one mouse per condition.

The Glioma-Infiltrating T Cell Receptor Repertoire

Project description:While immune signaling has emerged as a defining feature of the glioma microenvironment, local selection of responding T cells and their anti-tumor potential as a population are difficult to measure directly in patients. High-throughput sequencing of T cell receptor repertoires (TCRseq) provides a population-wide statistical description of how T cells respond to disease. Here, we define new immunophenotypes in glioma based on TCRseq and RNA-Seq of tumor tissue, non-neoplastic brain tissue, and peripheral blood from patients. Using information theory, we characterize antigen-driven selection in glioma and its relationship with the expression of distinct immune-functional pathways in the tumor microenvironment. Finally, we identify a strong relationship between usage of certain TCR in peripheral blood and the divergence of the infiltrating T cell population from the peripheral repertoire. We anticipate that these immunophenotypes will be foundational to monitoring and predicting response to anti-glioma vaccines and immunotherapy. We characterized the T cell receptor (TCR) repertoires of 11 high-grade glioma patients, three low-grade glioma patients, and thee non-glioma patients by TCRseq of brain-infiltrating T cells and matching peripheral blood. In addition, we obtained gene expression profiles from brain tissue of each patient by RNA-Seq. We additionally measured the TCR repertoires exclusively from peripheral blood of one additional non-glioma patient.
