The Phenotype of Circulating Follicular-Helper T Cells in Patients with Rheumatoid Arthritis Defines CD200 as a Potential Therapeutic Target [PDF]

, 2012
Rheumatoid arthritis (RA) is a systemic autoimmune disease primarily affecting synovial joints in which the development of autoantibodies represents a failure of normal tolerance mechanisms, suggesting a role for follicular helper T cells (TFH) in the ...

Continually recruited naïve T cells contribute to the follicular helper and regulatory T cell pools in germinal centers

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.

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.

Circulating follicular helper T cells are associated with mortality in sepsis

Frontiers in Immunology
IntroductionB-cell dysfunction is a key component of immune derangement in sepsis. Follicular helper T (Tfh) cells and follicular regulatory T (Tfr) cells play critical roles in B cell maturation and differentiation.

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

Compromised function of regulatory T cells in rheumatoid arthritis and reversal by anti-TNF alpha therapy [PDF]

, 2004
Regulatory T cells have been clearly implicated in the control of disease in murine models of autoimmunity. The paucity of data regarding the role of these lymphocytes in human autoimmune disease has prompted us to examine their function in patients with

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

The Coinhibitory Receptor CTLA-4 Controls B Cell Responses by Modulating T Follicular Helper, T Follicular Regulatory, and T Regulatory Cells [PDF]

Immunity, 2014
The receptor CTLA-4 has been implicated in controlling B cell responses, but the mechanisms by which CTLA-4 regulates antibody production are not known. Here we showed deletion of CTLA-4 in adult mice increased Tfh and Tfr cell numbers and augmented B cell responses.

Higher frequency of circulating regulatory T cells is associated with poor outcomes in patients with colorectal cancer

Discover Oncology
Background While immune dysregulation significantly influences colorectal cancer (CRC) progression, this study aimed to investigate the levels of circulating regulatory T cells (cTreg) and their subsets, follicular helper T cells (cTfh), and follicular ...
