Overview

The overarching goal of the Laboratory of Molecular Immunogenetics (LMI) is to understand the genetic and molecular pathways that drive the immune response under normal conditions or disease. The Lymphocyte Nuclear Biology group led by Rafael Casellas specifically studies the key nuclear events underlying immunoglobulin gene recombination, DNA damage, and transcription in B cells. Understanding the molecular pathways driving lymphocyte development and activation is essential for developing targeted therapeutic agents that can ameliorate immune system disorders with minimal side effects. To achieve these goals, we combine a wide range of technologies, including genetics and genomics, CRISPR-Cas9 editing, nanoscopy, Hi-C, cryo-Electron Microscopy, and bioinformatic tools.
