Nature Communications, 2023 Follicular helper T cells (TFH) mediate B cell selection and clonal expansion in germinal centers (GCs), and follicular regulatory T cells (TFR) prevent the emergence of self-reactive B cells and help to extinguish the reaction.

Frontiers in Immunology, 2022 Follicular T cells including T follicular helper (TFH) and T follicular regulatory (TFR) cells are essential in supporting and regulating the quality of antibody responses that develop in the germinal centre (GC).

T follicular regulatory cells in the regulation of B cell responses [PDF]
Trends in Immunology, 2015 High affinity antibodies result from interactions between B cells and T follicular helper (Tfh) cells in germinal centers (GCs). Recent studies have identified an effector subset of T regulatory cells termed T follicular regulatory (Tfr) cells that specifically controls GC responses by suppressing Tfh and B cells.

A T follicular helper cell origin for T regulatory type 1 cells
Cellular & Molecular Immunology, 2023 AbstractChronic antigenic stimulation can trigger the differentiation of antigen-experienced CD4+ T cells into T regulatory type 1 (TR1) cells, a subset of interleukin-10-producing Treg cells that do not express FOXP3. The identities of the progenitor(s) and transcriptional regulators of this T-cell subset remain unclear. Here, we show that the peptide-

T follicular regulatory cells: Guardians of the germinal centre? [PDF]
Scandinavian Journal of Immunology, 2020 AbstractIt is a central tenet of the clonal selection theory, that lymphocyte repertoires are tolerized to self‐antigens during their ontogeny. Germinal centres are the sites in secondary lymphoid tissues where B cells undergo affinity maturation and class‐switching to produce high‐affinity antibodies.

Differentiation, functions, and roles of T follicular regulatory cells in autoimmune diseases
Inflammation and Regeneration, 2021 T follicular helper cells participate in stimulating germinal center (GC) formation and supporting B cell differentiation and autoantibody production. However, T follicular regulatory (Tfr) cells suppress B cell activation.

Tumor Biology, 2017 Gastric cancer is one of the most common and aggressive malignancies. Both bacterial virulence factors and host chronic inflammation are thought to promote gastric cancer development. In this study, we investigated the potential involvement of follicular

Cell Reports, 2020 Summary: Within lymph nodes (LNs), T follicular helper (TFH) cells help B cells to produce antibodies, which can either be protective or autoreactive. Here, we demonstrate that murine LN stromal cells (LNSCs) suppress the formation of autoreactive TFH ...

PLoS Pathogens, 2016 During chronic HIV infection, viral replication is concentrated in secondary lymphoid follicles. Cytotoxic CD8 T cells control HIV replication in extrafollicular regions, but not in the follicle.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
