Tracking of clonotypes across time points, widely used in vaccination and cancer immunology domains.

As in many areas of investigation, advances in next generation sequencing (NGS) technologies, in which sequences are decoded on arrays and many millions of sequences can be read simultaneously, have been transformative for immune repertoire analysis. Gene usage estimation (correlation, Jensen-Shannon Divergence, clustering). Repertoire overlap analysis (common indices including overlap coefficient, Jaccard index and Morisita’s overlap index). Most methods are incorporated in a couple of main functions with clear naming-no more remembering dozens and dozens of functions with obscure names. Works on any data source you are comfortable with: R data frames, data tables from data.table, databases like MonetDB, Apache Spark data frames via sparklyr īeginner-friendly. Supports all popular TCR and BCR analysis and post-analysis formats, including single-cell data: ImmunoSEQ, IMGT, MiTCR, MiXCR, MiGEC, MigMap, VDJtools, tcR, AIRR, 10XGenomics, ArcherDX. The package automatically detects the format of your files-no more guessing what format is that file, just pass them to the package Fast and easy manipulation of immune repertoire data: © American Association for Clinical Chemistry 2020.Data agnostic. UMI error-free sequencing immune repertoire next-generation sequencing unique molecular identifier γδ T cell. Our approach is simple, flexible, and can easily be implemented in any molecular laboratory. Ultrasensitive immune repertoire sequencing strategy enables quantification of individual and specific clonotypes in a background that can be applied to clinical as well as basic application areas. Healthy donors displayed oligoclonal expansion of γδ T cells and similar frequencies of clonotypes were detected in both enrichment and nonenriched samples. The method corrected for sequencing-depended quantification bias and polymerase-induced errors and could be applied to both enriched and nonenriched cells. The 32-panel assay displayed wide dynamic range, high reproducibility, and analytical sensitivity with single-nucleotide resolution. The protocol was validated on synthetic reference molecules and blood samples of healthy individuals. We constructed a 32-panel assay that captured the full diversity of the recombined T-cell receptor delta loci in γδ T cells. The ultrasensitive immune repertoire sequencing method used PCR-introduced unique molecular identifiers. Here, we developed a sequencing method that overcame these issues and applied it to γδ T cells, a cell type that plays a unique role in immunity, autoimmunity, homeostasis of intestine, skin, adipose tissue, and cancer biology. However, current sequencing protocols display limitations with nonuniform amplification and polymerase-induced errors during sequencing. Immune repertoire sequencing of the T-cell receptor can identify clonotypes that have expanded as a result of antigen recognition or hematological malignancies. 7 Department of Clinical Genetics and Genomics, Sahlgrenska University Hospital, Gothenburg, Sweden.6 Respiratory Inflammation and Autoimmunity, IMED Biotech Unit, AstraZeneca, Gothenburg, Sweden.5 Department of Clinical Neuroscience, Institute of Neuroscience and Physiology, Sahlgrenska Academy at University of Gothenburg, Gothenburg, Sweden.4 Department of Microbiology and Immunology, Institute of Biomedicine, Sahlgrenska Academy at University of Gothenburg, Medicinaregatan 7A, University of Gothenburg, Gothenburg, Sweden. ![]() 3 Translational Science & Experimental Medicine, Research and Early Development, Respiratory, Inflammation and Autoimmune (RIA), Gothenburg, Sweden.2 Wallenberg Centre for Molecular and Translational Medicine, University of Gothenburg, Gothenburg, Sweden.1 Sahlgrenska Center for Cancer Research, Department of Laboratory Medicine, Institute of Biomedicine, Sahlgrenska Academy at University of Gothenburg, Gothenburg, Sweden.
