Plasticity within the αβ+CD4+ T-cell lineage: when, how and what for? [PDF]

Open Biology, 2013
Following thymic output, αβ+CD4+ T cells become activated in the periphery when they encounter peptide–major histocompatibility complex. A combination of cytokine and co-stimulatory signals instructs the differentiation of T cells into various lineages ...

Follicular Helper T Cells in Autoimmunity

Current Diabetes Reports, 2016
The development of multiple disease-relevant autoantibodies is a hallmark of autoimmune diseases. In autoimmune type 1 diabetes (T1D), a variable time frame of autoimmunity precedes the clinically overt disease. The relevance of T follicular helper (TFH) cells for the immune system is increasingly recognized.

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 ...

TIGIT-positive circulating follicular helper T cells display robust B-cell help functions: potential role in sickle cell alloimmunization

Haematologica, 2015
T follicular helper cells are the main CD4+ T cells specialized in supporting B-cell responses, but their role in driving transfusion-associated alloimmunization is not fully characterized.

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

The adaptor molecule CD2AP in CD4 T cells modulates differentiation of follicular helper T cells during chronic LCMV infection. [PDF]

PLoS Pathogens, 2018
CD4 T cell-mediated help to CD8 T cells and B cells is a critical arm of the adaptive immune system required for control of pathogen infection. CD4 T cells express cytokines and co-stimulatory molecules that support a sustained CD8 T cell response and ...

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.

T follicular helper cell diversity and plasticity [PDF]

Trends in Immunology, 2013
CD4(+) T helper (Th) cells play an instrumental role in orchestrating adaptive immune responses to invading pathogens through their ability to differentiate into specialized effector subsets. Part of this customized response requires the development of T follicular helper (Tfh) cells, which provide help to B cells for the generation of germinal centers

FACS Staining for Follicular Helper T Cells

Bio-Protocol, 2012
Germinal center is the primary site for B cells to undergo somatic hypermutation and class switching. A recently discovered subset of T cells known as T follicular helper (TFH) cells are essential for germinal center reaction and thus have been the ...

Follicular Helper T Cells: Lineage and Location [PDF]

Immunity, 2009
Follicular helper T (Tfh) cells are the class of effector T helper cells that regulates the step-wise development of antigen-specific B cell immunity in vivo. Deployment of CXCR5+ Tfh cells to B cell zones of lymphoid tissues and stable cognate interactions with B cells are central to the delivery of antigen-specific Tfh cell function.
