CD4(+) regulatory T (Treg) cells expressing CD25 and the transcription factor forkhead box P3 (FOXP3) are indispensable for immunological self-tolerance and homeostasis. FOXP3(+)CD25(+)CD4(+) T cells in humans, however, are heterogeneous in function and differentiation status, including suppressive or nonsuppressive cells as well as resting or activated Treg cells. We have searched for cell sur...
BACKGROUND Decreased infiltration of Foxp3+ T regulatory cell (Treg) is considered to be critical for the Th1/Th2 dysregulation of nasal polyps, while the cellular mechanism underlying Foxp3+ Treg insufficiency is currently not well defined. METHODS We attempted to investigate the tissue expression of phosphorylated mammalian target of rapamycin (pmTOR) and infiltration of Foxp3+ Tregs in 28 ...
AIMS Medullary breast cancer (MBC) is a biologically distinct subtype of breast cancer characterized by prominent lymphocytic infiltrates and a favourable clinical outcome. Tumour-infiltrating CD8+ effector T cells may contribute to the good prognosis of this type of cancer; however, certain subtypes of lymphocyte, such as FoxP3+ regulatory T cells (Tregs), can also suppress antitumour immunity...
Foxp3 is essential for the commitment of differentiating thymocytes to the regulatory CD4(+) T (T reg) cell lineage. In humans and mice with a genetic Foxp3 deficiency, absence of this critical T reg cell population was suggested to be responsible for the severe autoimmune lesions. Recently, it has been proposed that in addition to T reg cells, Foxp3 is also expressed in thymic epithelial cells...
Regulatory T cells (Tregs) are a specific subset of lymphocytes that are critical for the maintenance of self-tolerance. Expression levels of the transcription factor Foxp3 have been causally associated with Treg differentiation and function. Recent studies show that Foxp3 can also be transiently expressed in effector T cells; however, stable Foxp3 expression is required for development of a fu...
Background: Multiple sclerosis (MS) is a chronic inflammatory disorder of the CNS characterized by destruction of the myelin sheath, gliosis and progressive neurological dysfunction. The regulatory T (Treg) cells play a major role in the control of the autoimmunity and inflammation. The forkhead box p3 (FOXP3) is a central molecule in the function of Treg cells that play an important role in th...
Abstract Purpose: Foxp3 T-regulatory (Treg) cells are key to immune homeostasis but the function of paired amphipathic helix protein, Sin3a, is unknown. Methods: We studied effects Sin3a deletion in Treg cells. Results: Sin3a−/− FoxP3Cre mice died from severe autoimmunity by 2–3 weeks birth. Mice had enlarged lymph nodes, inflammation lungs, skin, livers and kidneys autoantibodies islet cells, ...
BACKGROUND FOXP3+ regulatory T cells (Tregs) are critical for preventing intestinal inflammation. However, FOXP3+ T cells are paradoxically increased in the intestines of patients with the inflammatory bowel disease (IBD) ulcerative colitis (UC) or Crohn's disease (CD). We determined whether these FOXP3+ cells in IBD patients share or lack the phenotype of such cells from patients without IBD. ...
