In-vitroeffect of pembrolizumab on different T regulatory cell subsets

Induction 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 ...

Regulatory T Cell Subsets in Filarial Infection and Their Function

Filarial infections in humans are chronic infections that cause significant morbidity. The chronic nature of these infections with continuous antigen release is associated with a parasite-specific T cell hypo-responsiveness that may over time also affect the immune responses to bystander antigens. Previous studies have shown the filarial parasite antigen-specific T cells hypo-responsiveness is ...

Neuropilin-1 distinguishes natural and inducible regulatory T cells among regulatory T cell subsets in vivo

Foxp3(+) CD4(+) T helper cells called regulatory T (T reg) cells play a key role in controlling reactivity to self-antigens and onset of autoimmunity. T reg cells either arise in thymus and are called natural T reg (nT reg) cells or are generated in the periphery through induction of Foxp3 and are called inducible T reg (iT reg) cells. The relative contributions of iT reg cells and nT reg cells...

The Immunomodulatory Effect of Cyclophosphamide on Regulation of T-Cell Subsets and Antigen Presenting Cells.

CD27 expression on CD4+ T cells differentiates effector from regulatory T cell subsets in the lung.

Beryllium exposure in the workplace can result in chronic beryllium disease, a granulomatous lung disorder characterized by CD4(+) T cell alveolitis and progressive lung fibrosis. A large number of the CD4(+) T cells recruited to the lung in chronic beryllium disease recognize beryllium in an Ag-specific manner and express Th1-type cytokines following T cell activation. Beryllium-responsive CD4...
