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-

CVID-associated TACI mutations affect autoreactive B cell selection and activation [PDF]

, 2013
Common variable immune deficiency (CVID) is an assorted group of primary diseases that clinically manifest with antibody deficiency, infection susceptibility, and autoimmunity.

Follicular regulatory T cells: a novel target for immunotherapy?

Clinical & Translational Immunology, 2020
High‐affinity antibodies are produced during multiple processes in germinal centres (GCs), where follicular helper T (Tfh) cells interact closely with B cells to support B‐cell survival, differentiation and proliferation.

Follicular regulatory T cells inhibit the development of granzyme B–expressing follicular helper T cells [PDF]

JCI Insight, 2019
T follicular regulatory (TFR) cells are found in the germinal center (GC) response and help shape the antibody (Ab) response. However, the precise role of TFR cells in the GC is controversial. Here, we addressed TFR cell function using mice with impaired TFR cell development ( Bcl6-flox/Foxp3-cre

Proinflammatory follicular helper T cells promote immunoglobulin G secretion, suppress regulatory B cell development, and correlate with worse clinical outcomes in gastric cancer

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

Lymph Node Stromal Cells Generate Antigen-Specific Regulatory T Cells and Control Autoreactive T and B Cell Responses

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 ...

Freeze-thaw lysates of P. falciparum-infected red blood cells induce differentiation of functionally competent regulatory T cells from memory T cells. [PDF]

, 2012
: In addition to naturally occurring regulatory T (nTreg) cells derived from the thymus, functionally competent Treg cells can be induced in vitro from peripheral blood lymphocytes in response to T-cell receptor stimulation with cytokine co-stimulation ...

Follicular Regulatory CD8 T Cells Impair the Germinal Center Response in SIV and Ex Vivo HIV Infection.

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.

T Follicular Regulatory Cell Suppression of T Follicular Helper Cell Function Is Context-Dependent in vitro

Frontiers in Immunology, 2020
The production of antibody-secreting plasma cells and memory B cells requires the interaction of T follicular helper (Tfh) cells with B cells in the follicle and is modulated by T follicular regulatory (Tfr) cells. We compare the effects of Tfr cells in an in vitro model of bystander Tfh function in the absence of BCR engagement and in a model in which

Modulation of the CD8+-T-cell response by CD4+ CD25+ regulatory T cells in patients with Hepatitis B virus infection [PDF]

, 2005
CD4+ CD25+ regulatory T cells have been shown to maintain peripheral tolerance against self and foreign antigens. In this study we analyzed the effect of circulating CD4+ CD25+ T cells on CD8+-T-cell responses of patients with chronic and resolved ...
