Regulatory 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 کاملTargeting regulatory T cells in cancer.
Infiltration of tumors by regulatory T cells confers growth and metastatic advantages by inhibiting antitumor immunity and by production of receptor activator of NF-κB (RANK) ligand, which may directly stimulate metastatic propagation of RANK-expressing cancer cells. Modulation of regulatory T cells can enhance the efficacy of cancer immunotherapy. Strategies include depletion, interference wit...
متن کاملImmunotherapy approaches targeting regulatory T-cells.
The immune system prevents establishment and progression of cancer through innate and adaptive surveillance. However, some cancerous cells successfully evade the immune system. Regulatory T-cells (Tregs) facilitate such evasion. Tregs may be the factor responsible for the limited success of human tumor immunotherapy to date. To improve immunotherapy, it is thought that the number of Tregs and t...
متن کاملTargeting T regulatory cells in autoimmune diseases.
Among the several mechanisms that play a role in maintaining peripheral self-tolerance is the existence of a unique CD4+CD25+ population of naturally occurring regulatory T cells, which actively prevent both the activation and the effector function of autoreactive T cells that have escaped different mechanisms of tolerance. Many studies have shown the benefit of targeting this cell population b...
متن کاملTargeting regulatory T cells in tumors.
Regulatory T (Treg ) cells play a crucial role in maintaining peripheral tolerance and preventing autoimmunity. However, they also represent a major barrier to effective antitumor immunity and immunotherapy. Consequently, there has been considerable interest in developing approaches that can selectively or preferentially target Treg cells in tumors, while not impacting their capacity to maintai...
