Summary of "Follicular regulatory T cells are associated with β-cell autoimmunity and the development of type 1 diabetes."

Impaired follicular regulatory T (Tfr) cells enhance T follicular helper (Tfh) cells activity, resulting in the expansion of autoreactive B cells and autoantibody production. However, the role of Tfr cells in the pathogenesis of type 1 diabetes (T1D) is unclear.

MiR-155 controls follicular Treg cell-mediated humoral autoimmune intestinal injury by inhibiting CTLA-4 expression.

High expression levels of miR-155 are involved in the pathogenesis of inflammatory bowel disease (IBD). We observed an increase in miR-155 in peripheral regulatory T (Treg) cells from IBD patients. Mi...

Allergen immunotherapy improves defective follicular regulatory T cells in patients with allergic rhinitis.

The function of follicular regulatory T (Tfr) cells, especially in regulating IgE production in allergic diseases, is poorly understood.

Medical and Biotech [MESH] Definitions

Non-hematopoietic cells, with extensive dendritic processes, found in the primary and secondary follicles of lymphoid tissue (the B cell zones). They are different from conventional DENDRITIC CELLS associated with T-CELLS. They are derived from MESENCHYMAL STEM CELLS and are negative for class II MHC antigen and do not process or present antigen like the conventional dendritic cells do. Instead, follicular dendritic cells have FC RECEPTORS and C3B RECEPTORS that hold antigen in the form of ANTIGEN-ANTIBODY COMPLEXES on their surfaces for long periods for recognition by B-CELLS.

CD4-positive T cells that inhibit immunopathology or autoimmune disease in vivo. They inhibit the immune response by influencing the activity of other cell types. Regulatory T-cells include naturally occurring CD4+CD25+ cells, IL-10 secreting Tr1 cells, and Th3 cells.

Process whereby the immune system reacts against the body's own tissues. Autoimmunity may produce or be caused by AUTOIMMUNE DISEASES.

Sarcoma of FOLLICULAR DENDRITIC CELLS most often found in the lymph nodes. This rare neoplasm occurs predominately in adults.

A heterogeneous group of immunocompetent cells that mediate the cellular immune response by processing and presenting antigens to the T-cells. Traditional antigen-presenting cells include MACROPHAGES; DENDRITIC CELLS; LANGERHANS CELLS; and B-LYMPHOCYTES. FOLLICULAR DENDRITIC CELLS are not traditional antigen-presenting cells, but because they hold antigen on their cell surface in the form of IMMUNE COMPLEXES for B-cell recognition they are considered so by some authors.
