Role of CD4CD25FOXP3 Regulatory T Cells in Psoriasis.
BACKGROUND CD4(+)CD25(high+)regulatory T cells (Tregs) are considered to be of vital importance for maintaining immunologic self-tolerance and preventing autoimmune diseases. These cells have been found to be deficient in skin lesions and in the peripheral blood of patients with psoriasis. OBJECTIVE To investigate the role of Tregs in the pathogenesis of psoriasis and to evaluate the changes ...
متن کاملRapamycin-treated human endothelial cells preferentially activate allogeneic regulatory T cells.
Human graft endothelial cells (ECs) can act as antigen-presenting cells to initiate allograft rejection by host memory T cells. Rapamycin, an mTOR inhibitor used clinically to suppress T cell responses, also acts on DCs, rendering them tolerogenic. Here, we report the effects of rapamycin on EC alloimmunogenicity. Compared with mock-treated cells, rapamycin-pretreated human ECs (rapa-ECs) stimu...
متن کاملHuman Endothelial Cells Modulate CD4+ T Cell Populations and Enhance Regulatory T Cell Suppressive Capacity
Endothelial cells (ECs) line the luminal surface of blood vessels and have an active role in the recruitment of leukocytes, including immune cell activation. Regulatory T cells (Tregs) are immune suppressor cells that maintain peripheral tolerance and must interact with the endothelium as they traffic into tissue. We hypothesized that human ECs could modulate Tregs and their suppressor function...
متن کاملRegulatory T Cells in Colorectal Cancer
One of the essential protection mechanisms of immune system is Treg cells which play an important role in maintenance ofimmune homeostasis. However, they may also inhibit immune functions against tumor cells. It has been reported that Treg cellsare increased in patients suffering from different types of cancer. Increased number of Treg cells has been shown in tumor lymphnodes, peripheral blood,...
متن کاملEvaluation 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...
