Dynamics of Suppressor T Cells
Immunity in the absence of autoimmunity reflects " self– nonself " discrimination by the immune system. The search for mechanisms preventing autoimmunity or enabling " self " tolerance has been at the root of immunology as evidenced by ample conceptual framework, rhetoric, sophism, and experimental data. A full understanding of such mechanisms would facilitate a large number of therapeutic inte...
متن کاملRegulatory T Cells and Myeloid-Derived Suppressor Cells in Patients with Peptic Ulcer and Gastric Cancer
Background: Regulatory T Cells (Tregs) and Myeloid-Derived Suppressor Cells (MDSCs) are two main regulatory cells modulating the immune responses in inflammation and cancer. Objective: To investigate and compare Tregs and MDSCs in peptic ulcer and gastric cancer. Methods: Patients with dyspepsia were selected and divided into three groups of non-ulcer dyspepsia (NUD, n=22), peptic ulcer disease...
متن کاملAltered Suppressor Function of Regulatory T Cells in Type 1 Diabetes
Background: Type 1 diabetes (T1D) is a T cell mediated autoimmune disease targeting the insulin-producing β cells within pancreatic islets. Autoimmune diseases may develop as a consequence of altered balance between regulatory (Tregs) and autoreactive T cells. Objectives: To evaluate Treg cells frequency and suppressive function in the peripheral blood of newly diagnosed T1D patients in compari...
متن کاملCharacterization of efferent T suppressor cells induced by Paracoccidioides brasiliensis-specific afferent T suppressor cells.
Previously, we reported that Paracoccidioides brasiliensis culture filtrate antigen (Pb.Ag) when injected i.v. into mice induces antigen-specific suppressor cells which down-regulate the anti-P. brasiliensis delayed-type hypersensitivity (DTH) response. The suppressor cells are present in both spleens and lymph nodes of Pb.Ag-treated animals and suppress the afferent limb but not the efferent l...
