Overview

Targeting BTK alters IgA production and microbiota in type 1 diabetes, indicating changes in mucosal immunity.

Key Points

  • To investigate the role of Bruton’s Tyrosine Kinase in IgA production and microbiota modulation in type 1 diabetes.
  • Evaluated IgA-A.M. interactions in Btk-/-NOD and WT NOD mice
  • Monocolonized mice with Akkermansia muciniphila (A.M.) in a germ-free environment
  • Isolated B cells from Peyer’s Patches and cultured to produce monoclonal antibodies
  • Assessed B cell receptor sequencing to analyze Btk-deficiency effects
  • Btk-deficiency resulted in decreased IgA production and IgA-coating of A.M.
  • Monoclonal antibodies binding A.M. were identified for future studies
  • Akkermansia muciniphila prevented symptomatic type 1 diabetes in Btk-/-NOD mice
