New Tfr cell model uncovers molecular switches that restrain antibody responses

For the immune system to effectively combat pathogens, antibody responses must be precisely controlled.

So-called follicular regulatory T cells (Tfr cells) play a key role in this process by limiting excessive immune responses and helping to maintain immune tolerance.

Researchers at the University Hospital Bonn (UKB) and the University of Bonn have now developed a robust laboratory method that allows Tfr cells to be generated from precursor cells and studied in a targeted manner.

The results were recently published in the journal Cellular & Molecular Immunology. ...
