Mapping the Lineage Relationship between CXCR5+ and CXCR5− CD4+ T Cells in HIV-Infected Human Lymph Nodes

Cell Reports, 2019
Summary: CXCR5 is a key marker of follicular helper T (TFH) cells. Using primary lymph nodes (LNs) from HIV-infected patients, we identified a population of CXCR5− CD4+ T cells with TFH-cell-like features.

Ddb1 Is Essential for the Expansion of CD4+ Helper T Cells by Regulating Cell Cycle Progression and Cell Death

Frontiers in Immunology, 2021
Follicular helper T (TFH) cells are specialized CD4+ helper T cells that provide help to B cells in humoral immunity. However, the molecular mechanism underlying generation of TFH cells is incompletely understood.

T Follicular Helper Cell Heterogeneity

Annual Review of Immunology
T follicular helper (Tfh) cells specialize in helping B cells and are therefore critical contributors to the generation of humoral immunity. Tfh cells aid immunoglobulin class-switch recombination and support the germinal center response, thereby promoting immunoglobulin affinity maturation and the generation of humoral immune memory.

Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

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.

B Cell Help by CD1d-Rectricted NKT Cells

Antibodies, 2015
B cell activation and antibody production against foreign antigens is a central step of host defense. This is achieved via highly regulated multi-phase processes that involve a variety of cells of both innate and adaptive arms of the immune system.

Signaling Pathways in T Follicular Helper Cells [PDF]

The Journal of Immunology, 2010
Abstract Th cell functional subsets have unique transcriptional programs that form the molecular basis for T cell differentiation and functions. T follicular helper (TFH) cells have emerged as the main providers of T cell help to B cells during the germinal center (GC) reaction, where B cells undergo selection events through ...

New Territory for T Follicular Helper Cells [PDF]

Immunity, 2013
T follicular helper (Tfh) cells have been thrust into the limelight since the recent discovery of their unique developmental program. Exciting new insights into the regulation of Tfh development, migration, and function were presented at the first Gordon Conference on Tfh cells held in Hong Kong and summarized here.
