Human blood CXCR5(+)CD4(+) T cells are counterparts of T follicular cells and contain specific subsets that differentially support antibody secretion.
Although a fraction of human blood memory CD4(+) T cells expresses chemokine (C-X-C motif) receptor 5 (CXCR5), their relationship to T follicular helper (Tfh) cells is not well established. Here weExpand

Induction of ICOS+CXCR3+CXCR5+ TH Cells Correlates with Antibody Responses to Influenza Vaccination
A T cell subset that emerges in blood after seasonal influenza vaccinations correlates with the development of protective antibody responses. What Lies Beneath Although the seasonal flu vaccine,Expand

Phenotype and functions of memory Tfh cells in human blood.
Our understanding of the origin and functions of human blood CXCR5(+) CD4(+) T cells found in human blood has changed dramatically in the past years. These cells are currently considered to representExpand

Human dendritic cells induce the differentiation of interleukin-21-producing T follicular helper-like cells through interleukin-12.
T follicular helper (Tfh) cells help development of antibody responses via interleukin-21 (IL-21). Here we show that activated human dendritic cells (DCs) induced naive CD4(+) T cells to becomeExpand

The cytokine TGF-β co-opts signaling via STAT3-STAT4 to promote the differentiation of human TFH cells
Understanding the developmental mechanisms of follicular helper T cells (TFH cells) in humans is relevant to the clinic. However, the factors that drive the differentiation of human CD4+ helper TExpand

Regulation of human helper T cell subset differentiation by cytokines.
Since the discovery of Th1 and Th2 cells in the late 1980s, the family of effector CD4(+) helper T (Th) cell subsets has expanded. The differentiation of naïve CD4(+) T cells is largely determinedExpand

Human tonsil B-cell lymphoma 6 (BCL6)-expressing CD4+ T-cell subset specialized for B-cell help outside germinal centers
T follicular helper (Tfh) cells represent a Th subset engaged in the help of B-cell responses in germinal centers (GCs). Tfh cells abundantly express the transcription repressor B-cell lymphoma 6Expand

Targeting human dendritic cell subsets for improved vaccines.
Dendritic cells (DCs) were discovered in 1973 by Ralph Steinman as a previously undefined cell type in the mouse spleen and are now recognized as a group of related cell populations that induce andExpand

IL-12 receptor β1 deficiency alters in vivo T follicular helper cell response in humans.
Antibody responses represent a key immune protection mechanism. T follicular helper (Tfh) cells are the major CD4(+) T-cell subset that provides help to B cells to generate an antibody response. TfhExpand

IL-7 Induces Immunological Improvement in SIV-Infected Rhesus Macaques under Antiviral Therapy1
Despite efficient antiretroviral therapy (ART), CD4+ T cell counts often remain low in HIV-1-infected patients. This has led to IL-7, a crucial cytokine involved in both thymopoiesis and peripheral TExpand
