Immune Repertoire Analysis
with Vidjil

Rennes (France), 22-23 May 2024

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 lymphoid populations. With dedicated Rep-Seq bioinformatics methods and software, clinicians and researchers can now qualify and sometimes quantify the heterogeneity of these lymphoid populations.

This sixth workshop is intended for users and developers of Vidjil, to share experience, protocols and results, to raise questions and decide development priorities, and possibly to set up new collaborations between biologists and bioinformaticians. The workshop will include invited talks, hematology, immunology and bioinformatics talks from the users and developers of Vidjil, and practical hands-on sessions on participant data. The Vidjil Workshop usually takes place every 18 months. The previous workshops (2016, 2017, 2019, 2020, 2022) gathered at each edition between 30 and 40 scientists from 5 to 7 countries.

Preliminary Program

A more detailed program will be available in March 2024. The workshop includes invited talks, hematology and bioinformatics talks from the users and developers of Vidjil, and practical hands-on sessions on participant data. We expect that one participant from each group will do a short presentation of his research or clinical work, and, if applicable, of the results obtained with Vidjil or with other software.

For the practical sessions, the participants are invited to bring a laptop and some of their NGS data (fasta / fastq / fastq.gz files). The data can also be uploaded before the workshop into user accounts on before the workshop. We also provide public test data for the people who do not currently have their own NGS Rep-Seq data.
