Clinical Scorecard: Knock-in Mice with Aquaporin-5 Heavy Chain VDJ Modification Uncover the Role of Molecular Mimicry in Initiating and Diversifying Autoreactive B-Cell Responses

At a Glance

CategoryDetail
ConditionAutoimmunity
Key MechanismsMolecular mimicry triggering autoreactive B-cell responses
Target PopulationMice with specific genetic modifications (A5H mice)
Care SettingResearch laboratory

Key Highlights

  • A5H mice exhibit normal B-cell development with reduced anergy-associated B cells.
  • Immunization with PmE-L leads to robust production of anti-AQP5E autoantibodies.
  • Allelic inclusion enhances autoreactive B-cell activation in heterozygous mice.
