Randomized trial examines BCL6's influence on IgM+ memory B cell development, highlighting Tfh independence.

This research aims to understand how CD4+ T cell interactions with B cells influence the generation of specific memory B cell subsets.
Utilized genetic ablation and antibody depletion techniques to analyze CD4+ T cell/B cell interactions.
Defined signaling pathways necessary for the differentiation of memory B cell populations.
Investigated the role of BCL6 in MBC development in the context of germinal center activity.
Demonstrated that BCL6 and CD4+ T cell involvement is crucial for the differentiation of functional IgM+ memory B cells.
Found that IgM+ memory B cells, particularly CD73+CD80+, develop in a Tfh-independent manner.
Showed that BCL6 upregulation can predict the longevity and functionality of memory B cells.

Pritchard et al. (2026) studied this question.
