High-Throughput Analysis of V(D)J Immune Repertoire

Vidjil is an open-source platform for the analysis of high-throughput sequencing data from lymphocytes. V(D)J recombinations in lymphocytes are essential for immunological diversity. They are also useful markers of pathologies, and in leukemia, are used to quantify the minimal residual disease during patient follow-up. High-throughput sequencing (NGS/HTS) now enables the deep sequencing of a lymphoid population with dedicated Rep-Seq methods and software.

Vidjil-algo is the high-throughput algorithm of the Vidjil platform extracting V(D)J junctions and gather them into clones. This analysis is based on a seed heuristics and is fast and scalable, as, in the first phase, no alignment is performed with database germline sequences. Vidjil also contains a web application linked to a patient database for visualization and analysis of clones and their tracking along the time in a MRD setup or in a immunological study.

Vidjil is developed by a passionate team with fast response, from the Bonsai bioinformatics team of the CRIStAL (CNRS, U. Lille) and Inria Lille research centers, in Lille, France, and by the VidjilNet consortium. This work is in collaboration with the department of Hematology of CHRU Lille, the Functional and Structural Genomic Platform (U. Lille 2, IFR-114, IRCL), and the EuroClonality-NGS working group, and is supported by SIRIC ONCOLille (Grant INCa-DGOS-Inserm 6041), Région Nord-Pas-de-Calais (ABILES), Inria, and by Université Lille 1 (PPF Bioinformatique). The methods were presented at the JOBIM 2013 and ASH 2014 conferences, and are described in the following papers:
