MHC-independent genetic factors control the magnitude of CD4+ T cell responses to amyloid-β peptide in mice through regulatory T cell-mediated inhibition.
Accumulation of amyloid-β peptide (Aβ) is considered the triggering factor of pathogenic lesions in Alzheimer's disease (AD), and vaccines targeting Aβ are promising therapeutic options. However, the occurrence of meningoencephalitides attributed to T cell responses in 6% of Aβ-immunized patients underscores the need for a better understanding of T cell responses to Aβ. We characterized the par...
متن کاملOral tolerance for delayed type hypersensitivity contribution of local and peripheral mechanisms
Oral tolerance is a physiological immune mechanism, which controls the outcome of deleterious hypersensitivity reactions to environmental antigens absorbed through the gastrointestinal tract, and maintains homeostasis. Using a mouse model of oral tolerance of delayed type hypersensitivity to contact allergens, i.e. haptens, we have examined the mechanisms involved in the induction of oral toler...
متن کاملHuman Leukocyte Antigen-G Expression on Dendritic Cells Induced by Transforming Growth Factor-β1 and CD4+ T Cells Proliferation
Background: During antigen capture and processing, mature dendritic cells (DC) express large amounts of peptide-MHC complexes and accessory molecules on their surface. DC are antigen-presenting cells that have an important role in tolerance and autoimmunity. The transforming growth factor-beta1 (TGF-β1) cytokine has a regulatory role on the immune and non-immune cells. The aim of this study is ...
متن کاملA Historic Review of the Role of CD4+ T-Cell Subsets in Development of the Immune Responses against Cutaneous and Visceral Leishmaniases
The heterogeneity of CD4+ T cells has been investigated since the late 1970s, when their Th1 and Th2 subsets were coined. Later studies on the cutaneous form of the Leishmaniasis were focused on the experimental models of Leishmania major infection using the susceptible BALB/c and the resistant C57BL/6 mice. At the early 21st century, the regulatory T-cells subpopulation was introduced and its ...
متن کاملInduction of T Regulatory Subsets from Naïve CD4+ T Cells after Exposure to Breast Cancer Adipose Derived Stem Cells
Background: Adipose derived stem cells (ASCs) provoke the accumulation and expansion of regulatory T cells, leading to the modulation of immune responses in tumor microenvironment. Objective: To assess the effect of tumoral ASCs on the trend of regulatory T cells differentiation. Methods: Peripheral blood naïve CD4+ T cells were co-cultured with ASCs derived from breast cancer or normal breast ...
