    On AIRR 15: Germline databases or adventures into the allelic underworld with Dr. Corey Watson and Dr. William Lees
    Oct 30 2023
    Dr. Corey Watson is an Associate Professor at the University of Louisville. His work focuses on characterising and cataloguing antibody genetic diversity in human and mouse to better understand disease susceptibility and clinical health outcomes. Dr. William Lees is a researcher at University of London. His work focuses on developing Adaptive Immune Receptor (AIR) reference sets for diverse species and the annotation of experimental sequence data. In this episode we talk about the recent work by the Germline Database Working Group of the AIRR-Community. The accuracy of V and J gene segment assignment improves with the quality of the reference germline set. The accurate assignment is critical for characterization of somatic hypermutation. We discuss the challenges in creating a database to hold all relevant and potentially relevant germline information, especially in the light of increased discovery rate through technological advances and improved analysis pipelines. We also reflect on the complexity in handling personalised germline reference sets. The episode is hosted by Dr. Ulrik Stervbo and Dr. Zhaoqing Ding.

    Jul 2 2023

    Maxim Zaslavsky is a computer scientist using machine learning to address problems in immunology. He is currently PhD student at Stanford University.

    Scott D. Boyd is a physician-scientist and Professor of Pathology and of Food Allergy and Immunology at Stanford University. His group is focused on using high-throughput DNA sequencing and single-cell experiments to analyse human immune responses to infection and vaccination.

    We discuss the preprint “Disease diagnostics using machine learning of immune receptors”, available at BioRxiv: https://doi.org/10.1101/2022.04.26.489314. The work is led by Maxim Zaslavsky with Scott Boyd the corresponding author. In the manuscript, the authors demonstrate how AIRR-seq and machine learning can be used in disease diagnostics.

    Dr. Xenophon Papademetris is Professor of Radiology and Biomedical Imaging, and Biomedical Engineering at Yale University, USA. The research of Prof. Papademetris is in the area of medical image analysis with a focus in the development of medical software.

    Dr. Papademetris provides an overview of the typical regulatory process for software classified as a medical device. We draw from his experience in the medical image field to design a high level route map for an imaginary company bringing to the market software to diagnose minimal residual disease.

    You can learn more about Medical Software development in Dr. Papademetris’s book Introduction to Medical Software: Foundations for Digital Health, Devices and Diagnostics (Cambridge University Press, 2022) and the Yale/Coursera class Introduction to Medical Software.

    On AIRR 10: Characterising B Cell Lymphomas or Profiting from a Focus on B Cells in Health and in Disease with Dr. Ralf Küppers
    Dec 29 2022

    Prof. Dr. Ralf Küppers is the director of Institute of Cell Biology (Tumor Research), University of Duisburg-Essen, Germany. The work of Prof. Küppers revolves around B cell differentiation and function together with pathogenesis of human B cell lymphomas - both Hodgkin and Non-Hodgkin lymphoma.

    We discuss how micro-dissection and Sanger sequencing is still the method of choice when analysing Hodgkin lymphoma and the V-gene usage and mutations in CLL as prognostic indicators before talking about tracking pathogenic clones when surveying for relapse during clinical follow up.
