Lineage specification and heterogeneity of T follicular helper cells

open access: yes, 2009
T follicular helper (Tfh) cells were originally described as a non-polarized CD4(+) T cell subset with follicular homing capacity and a potent ability to induce antibody production from B cells.

Integrated Multiomic Analysis Reveals an EBV‐Associated MIF–SPP1+ Macrophage Axis Linking Tumor Stemness and Immune Dysfunction in Nasopharyngeal Carcinoma

open access: yesAdvanced Science, EarlyView.
This study maps how Epstein–Barr virus reshapes the cellular ecosystem of nasopharyngeal carcinoma. It identifies SPP1+ macrophages as partners of stemness‐associated tumor cells and dysfunctional T cells, links tumor‐derived MIF to macrophage recruitment and programming, and shows that macrophage‐derived SPP1 promotes tumorsphere formation and impairs

Follicular lymphoma regulatory T-cell origin and function

open access: yesFrontiers 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,

Mesenchymal stromal cells support the viability and differentiation of follicular lymphoma-infiltrating follicular helper T-cells. [PDF]

open access: yes, 2014
The biology of follicular lymphoma (FL) is largely dictated by the immune-effector and stromal cells that comprise its tumor microenvironment. FL-infiltrating T-cell populations that are thought to be fundamental to FL biology are follicular helper T ...

Single‐Cell Insights Into Pathogenic Profile of Orchitis and SREBP2‐Associated Cholesterol Dysregulation in Spermatogenic Failure

open access: yesAdvanced Science, EarlyView.
A first single‐cell atlas of human orchitis reveals coordinated germ‐cell loss, somatic niche dysfunction, and immune‐metabolic remodeling. Aberrant SREBP2 activation in testicular somatic cells emerges as a central pathogenic node, while Fatostatin‐mediated inhibition of the SREBP pathway improves spermatogenesis, fibrosis, and lipid accumulation in a

CD4+T Cells: Differentiation and Functions

open access: yesClinical 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 ...

ICAMs support B cell interactions with T follicular helper cells and promote clonal selection. [PDF]

open access: yes, 2017
The germinal center (GC) reaction begins with a diverse and expanded group of B cell clones bearing a wide range of antibody affinities. During GC colonization, B cells engage in long-lasting interactions with T follicular helper (Tfh) cells, a process ...

CD86‐Positive Mature Tertiary Lymphoid Structures Are Associated With CD8+ T‐Cell Infiltration and Favorable Clinical Outcomes in Pancreatic Ductal Adenocarcinoma

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
CD86‐positive mature tertiary lymphoid structures were associated with increased intratumoral CD8+ T‐cell infiltration, a higher proportion of Granzyme B‐expressing CD8+ T cells in an exploratory analysis, and favorable clinical outcomes in pancreatic ductal adenocarcinoma.

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

open access: yesFrontiers 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 ...

Follicular Regulatory T Cells and Follicular Helper T Cells: Role in HIV Pathogenesis [PDF]

open access: yes, 2018
The role and function of human T follicular regulatory (TFR) cells in healthy individuals are not completely understood, partly due to its previous grouping with T follicular helper (TFH) cells and partly due to the difficulty in obtaining human ...
