IL-21 restricts T follicular regulatory T cell proliferation through Bcl-6 mediated inhibition of responsiveness to IL-2

Nature Communications, 2017
IL-21 is central to follicular helper T cell function and germinal centre responses. Here the authors show that IL-21 signalling directly inhibits T follicular regulatory cells by limiting Bcl-6-dependent IL-2 receptor expression.

The balance between conventional and unconventional T follicular helper cells influences autoreactive B cell responses

Cell Reports
Summary: Invariant natural killer T (iNKT) cells are activated by glycolipids presented on CD1d. When iNKT cells interact with and activate B cells, they can differentiate into iNKT follicular helper (iNKTfh) cells, and here, we investigate how this, in ...

Follicular lymphoma regulatory T-cell origin and function

Frontiers in Immunology
IntroductionFollicular Lymphoma (FL) results from the malignant transformation of germinal center (GC) B cells. FL B cells display recurrent and diverse genetic alterations, some of them favoring their direct interaction with their cell microenvironment,

CD4+T Cells: Differentiation and Functions

Clinical and Developmental Immunology, 2012
CD4+T cells are crucial in achieving a regulated effective immune response to pathogens. Naive CD4+T cells are activated after interaction with antigen-MHC complex and differentiate into specific subtypes depending mainly on the cytokine milieu of the ...

CCR9 Expressing T Helper and T Follicular Helper Cells Exhibit Site-Specific Identities During Inflammatory Disease

Frontiers in Immunology, 2019
CD4+ T helper (Th) cells that express the gut homing chemokine receptor CCR9 are increased in the peripheral blood of patients with inflammatory bowel disease and Sjögren's syndrome and in the inflamed lesions of autoimmune diseases that affect the ...

Regulation of T follicular helper cells by ICOS

Oncotarget, 2015
T follicular helper (TFH) cells are gatekeepers of the humoral immune response. Without help from this CD4+ T cell subset, B cells cannot differentiate into high-affinity memory B cells and antibody-producing long-lived plasma cells which are the basis of protective immune responses.

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.

Diagnostic Challenges in Nodal T-Follicular Helper (TFH) Cell Lymphoma

BioMed
Nodal T-follicular helper cell lymphomas comprise a biologically similar but morphologically diverse family of T-cell neoplasms, including angioimmunoblastic T-cell lymphoma, nodal T-follicular helper cell lymphoma, follicular-type, and nodal TFH ...
