Evaluation of Exhausted Regulatory T Cells in Preeclampsia
Background: The development of a maternal immune response to fetal antigens and deficiency in regulatory T-cells (Tregs) may lead to preeclampsia. A plausible explanation for the reduced Treg cell function in women with preeclampsia is the presence of exhausted Treg cells which express CD279 or programmed cell death receptor-1 (PD-1), a negative regulatory molecule associated w...
متن کاملCD4+ T Cells are Exhausted and Show Functional Defects in Chronic Lymphocytic Leukemia
Background: Chronic lymphocytic leukemia (CLL) is the most common adult leukemia in the western world. This health problem is caused due to the accumulation of mature B-lymphocytes in the peripheral blood and bone marrow. In the course of cancer, CD4+ T cells become “exhausted” and characterized with poor effector functions and the expression of multiple inhibitory receptors. Objective: To inve...
متن کاملRejuvenating Exhausted T Cells during Chronic Viral Infection
In a recent paper in Nature, show that the immunoreceptor PD-1 is upregulated by "exhausted" T cells during the chronic phase of viral infection in mice. Remarkably, blocking the interaction between PD-1 and its ligand, PD-L1, reactivates these T cells and reduces viral load.
متن کاملCD39 Expression Identifies Terminally Exhausted CD8+ T Cells
Exhausted T cells express multiple co-inhibitory molecules that impair their function and limit immunity to chronic viral infection. Defining novel markers of exhaustion is important both for identifying and potentially reversing T cell exhaustion. Herein, we show that the ectonucleotidse CD39 is a marker of exhausted CD8+ T cells. CD8+ T cells specific for HCV or HIV express high levels of CD3...
متن کاملThe Epigenetic Regulation of Blinatumomab Gene Expression: Tumor Cell-dependent T cell Response against Lymphoma Cells and Cytotoxic Activity
Conventional treatment for cancer such as surgical resection and chemotherapy can cause damage in cases with advanced cancers. Moreover, the identification of tumor-specific targets has great importance in T-cell therapies. For decades, T cell activity has been stimulated to improve anti-tumor activity. Bispecific antibodies have attracted strong interest from pharmaceutical companies, for thei...
