Inducible IL10+ Suppressor B Cells Inhibit CNS Inflammation and T Helper 17 Polarization

Inducible costimulator (ICOS) blockade inhibits accumulation of polyfunctional T helper 1/T helper 17 cells and mitigates autoimmune arthritis.

OBJECTIVES Inducible costimulator (ICOS) and its ligand (ICOSL) regulate T and B cell responses. Glucose-6-phosphate isomerase (G6PI)-induced arthritis requires T and B lymphocytes. It was hypothesised that blocking ICOS/ICOSL interactions ameliorates G6PI-induced arthritis and reduces G6PI-specific B and T lymphocyte responses. METHODS DBA/1 mice were injected with a blocking, non-depleting ...

Human regulatory T cells inhibit polarization of T helper cells toward antigen-presenting cells via a TGF-beta-dependent mechanism.

The molecular mechanisms used by regulatory T cells (Treg) to inhibit the effector phase of adaptive immune responses are still elusive. In the present work, we investigated the possibility that Treg may interfere with a basic biological function of T helper cells (T(H)): polarization of secretory machinery for dedicated help delivery. To address this question, we visualized by confocal microsc...

the roles of t helper 1, t helper 17 and regulatory t cells in the pathogenesis of sarcoidosis

sarcoidosis is a systemic granulomatous disorder of unidentified etiology, with a heterogeneous clinical presentation. it is characterized by a reduced delayed-type hypersensitivity to tuberculin and common antigens. the balance between th1, th17 and regulatory t(treg) cells controls t-cell proliferation and activation.the th17/treg ratio in the peripheral blood and bronchoalveolar lavage fluid...

T-helper-17, Regulatory T-helper Cells Related Serum Markers and IL-13 in the Outcome of Polytraumatic Patients with Bacteremia

Immediate T-Helper 17 Polarization Upon Triggering CD11b/c on HIV-Exposed Dendritic Cells.

Early on in human immunodeficiency virus (HIV) type 1 infection, gut T-helper (Th) 17 cells are massively depleted leading eventually to compromised intestinal barrier function and excessive immune activation. In contrast, the functional Th17 cell compartment of the gut is well-maintained in nonpathogenic simian immunodeficiency virus infection as well as HIV-1 long-term nonprogressors. Here, w...
