the efficacy of allergen immunotherapy for the treatment of allergic rhinoconjunctivitis with or without seasonal bronchial asthma and anaphylaxis caused by the sting of the hymenoptera class of insects has been clearly demonstrated in numerous well-designed, placebo-controlled trials. immunotherapy whether by subcutaneous injection of allergen extract or by oral/sublingual routes modifies peri...
CD4+CD25+ regulatory T (Treg) cells are potent modulators of alloimmune responses. In murine models of allogeneic bone marrow transplantation, adoptive transfer of donor CD4+CD25+ Treg cells protects recipient mice from lethal acute graft-versus-host disease (aGVHD) induced by donor CD4+CD25- T cells. Here we examined the differential effect of CD62L+ and CD62L- subsets of CD4+CD25+ Treg cells ...
The aim of the present study was to explore the effect of hypoxia on ovarian cancer. A total of 6 samples were analyzed: SKOV3‑IP cells (ovarian cancer cell line); SKOV3‑IP and regulatory T (Treg) cells; SKOV3‑IP and cytotoxic T lymphocytes (CTLs); SKOV3‑IP and natural killer (NK) cells; SKOV3‑IP co-cultured with CTLs and Treg cells; and SKOV3‑IP co-cultured with Treg cells and NK cells. The ex...
Variants of the Bach2 gene are linked to vitiligo, celiac disease, and type 1 diabetes, but the underlying immunological mechanisms are unknown. In this study, we demonstrate that Bach2 plays crucial roles in maintaining T cell quiescence and governing the differentiation, activation, and survival of Foxp3(+) regulatory T (Treg) cells. Bach2-deficient T cells display spontaneous activation and ...
Regulatory CD4 T (Treg) cells are comprised of a heterogeneous population of cells that play a vital role in suppressing inflammation and maintaining immune tolerance. The immunoregulatory function of Treg cells is especially important in the intestine where the mucosa is exposed to a diverse array of foreign antigens-including those derived from food and commensal bacteria. Treg cells are enri...
Both nature and induced regulatory T (Treg) lymphocytes are potent regulators of autoimmune and allergic disorders. Defects in endogenous Treg cells have been reported in patients with allergic asthma, suggesting that disrupted Treg cell-mediated immunological regulation may play an important role in airway allergic inflammation. In order to determine whether adoptive transfer of induced Treg c...
Regulatory T (Treg) cells maintain immune homeostasis by suppressing excessive immune responses. Treg cells induce tolerance against self- and foreign antigens, thus preventing autoimmunity, allergy, graft rejection, and fetus rejection during pregnancy. However, Treg cells also infiltrate into tumors and inhibit antitumor immune responses, thus inhibiting anticancer therapy. Depleting whole Tr...
Regulatory T (Treg) cells are a constitutively immunosuppressive subtype of T cells that contribute to the maintenance of immunological self-tolerance and immune homeostasis. However, the molecular mechanisms involved in the regulation of Treg cells remain unclear. In the present study, we identified ubiquitously expressed transcript (UXT) to be a novel regulator of human Treg-cell function. In...
Migration of activated regulatory T (Treg) cells to inflamed tissue is crucial for their immune-modulatory function. While metabolic reprogramming during Treg cell differentiation has been extensively studied, the bioenergetics of Treg cell trafficking remains undefined. We have investigated the metabolic demands of migrating Treg cells in vitro and in vivo. We show that glycolysis was instrume...
CD4(+) regulatory T (Treg) cells play an important role in the maintenance of immunological self-tolerance by suppressing immune responses against autoimmune diseases and cancer. Yet very little is known about the natural antigenic ligands that preferentially activate CD4(+) Treg cells. Here we report the establishment of tumor-specific CD4(+) Treg cell clones from tumor-infiltrating lymphocyte...
