Regulatory T cell: a protection for tumour cells
Characterized by immunosuppression regulatory T cells (Tregs) play a key role in maintaining immune tolerance. A growing number of tumours have been found with Tregs accumulating in microenvironment and patients with high density of Tregs in tumour stroma get a worse prognosis, which suggests that Tregs may inhibit anti-tumour immunity in stroma, resulting in a poor prognosis. In this paper, we...
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 کاملT Helper Cells Profile and CD4+CD25+Foxp3+Regulatory T Cells in Polycystic Ovary Syndrome
Background: Polycystic ovary syndrome (PCOS) is considered as the most common cause of female infertility that affects 4-10% of women in the reproductive age. Previous studies have shown the role of a balanced immune response in a successful pregnancy and fertility. Objective: To investigate the T helper cells type 1 (Th1) /Th2/Th17/Treg paradigms in peripheral blood of infertile PCOS compared ...
متن کاملA Distinct Function of Regulatory T Cells in Tissue Protection
Regulatory T (Treg) cells suppress immune responses to a broad range of non-microbial and microbial antigens and indirectly limit immune inflammation-inflicted tissue damage by employing multiple mechanisms of suppression. Here, we demonstrate that selective Treg cell deficiency in amphiregulin leads to severe acute lung damage and decreased blood oxygen concentration during influenza virus inf...
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...
