Human Foxp3-negative follicular regulatory T cells control IgE responses

, 2019
Antibody responses to most infectious and food protein antigens depend on help to B cells from specialised T follicular helper (Tfh) cells. A subset of Foxp3+ regulatory T cells (Tregs) has been described in mice, with a prominent role in repressing ...

Regulatory immune cells in transplantation. [PDF]

, 2012
Immune regulation is fundamental to any immune response to ensure that it is appropriate for the perceived threat to the host. Following cell and organ transplantation, it is essential to control both the innate immune response triggered by the injured ...

Freeze-thaw lysates of Plasmodium 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 TCR stimulation with cytokine costimulation.

Regulation of Germinal Center Reactions by B and T Cells

Antibodies, 2013
Break of B cell tolerance to self-antigens results in the development of autoantibodies and, thus, leads to autoimmunity. How B cell tolerance is maintained during active germinal center (GC) reactions is yet to be fully understood.

Regulation of the Germinal Center Reaction by Foxp3+ Follicular Regulatory T Cells

, 2011
Follicular helper T (TFH) cells participate in humoral responses providing selection signals to germinal center B cells. Recently, expression of CXCR5, PD-1, and the transcription factor Bcl-6 has allowed the identification of TFH cells.

Follicular regulatory T cells can be specific for the immunizing antigen and derive from naive T cells. [PDF]

, 2016
T follicular regulatory (Tfr) cells are a subset of Foxp3(+) regulatory T (Treg) cells that form in response to immunization or infection, which localize to the germinal centre where they control the magnitude of the response.

Imbalance of Circulatory T Follicular Helper and T Follicular Regulatory Cells in Patients with ANCA-Associated Vasculitis

Mediators of Inflammation, 2019
Antineutrophil cytoplasmic antibody- (ANCA-) associated vasculitis (AAV) is characterized by small-vessel inflammation in association with autoantibodies. Balance between T follicular helper (Tfh) cells and T follicular regulatory (Tfr) cells is critical

CD25(+) Natural Regulatory T Cells Are Critical in Limiting Innate and Adaptive Immunity and Resolving Disease following Respiratory Syncytial Virus Infection [PDF]

, 2010
Regulatory CD4(+) T cells have been shown to be important in limiting immune responses, but their role in respiratory viral infections has received little attention.
