Abstract
Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), is a global cause of death. Granuloma-associated lymphoid tissue (GrALT) correlates with protection during TB, but the mechanisms of protection are not understood. During TB, the transcription factor IRF4 in T cells but not B cells is required for the generation of the TH1 and TH17 subsets of helper T cells and follicular helper T (TFH)-like cellular responses. A population of IRF4+ T cells coexpress the transcription factor BCL6 during Mtb infection, and deletion of Bcl6 (Bcl6fl/fl) in CD4+ T cells (CD4cre) resulted in reduction of TFH-like cells, impaired localization within GrALT and increased Mtb burden. In contrast, the absence of germinal center B cells, MHC class II expression on B cells, antibody-producing plasma cells or interleukin-10-expressing B cells, did not increase Mtb susceptibility. Indeed, antigen-specific B cells enhance cytokine production and strategically localize TFH-like cells within GrALT via interactions between programmed cell death 1 (PD-1) and its ligand PD-L1 and mediate Mtb control in both mice and macaques.

Extended Data Fig. 10 Graphical abstract: Mtb specific B cells and Tfh-like cells interact to mediate protection against Mtb.
B cell effector functions including formation of GC B cells, IL-10 production and antibody/plasma cells have non-essential roles during in vivo Mtb infection. However, Mtb antigen-specific B cells interact with Tfh-like cells likely through PDL1-PD1 to drive differentiation and effective localization of cytokine-producing Tfh-like cells within GrALT to mediate Mtb control (left). Key transcription factors Irf4 and Bcl6 (blue text) are essential for differentiation of Tfh-like cells from naive CD4+ T cells. PD1-PDL1 (blue text) receptor-ligand axis likely drive Tfh-like cell localization and homing into GrALT but this interaction is independent of TCR-MHCII interaction, IL-10 production or antibody response (black text). Thus, Tfh-like cells and B cell interactions play critical roles in mediating Mtb control within GrALT.
