Immunotherapy 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 the right regulatory T-cell population for tumor immunotherapy
Regulatory T cells (Tregs) that suppress tumor-specific T cell-mediated immune responses are the subject of an intense wave of investigation. We recently reported that a subset of Tregs, namely effector/memory CD25(low) cells, are responsible for suppressing high avidity tumor-specific T cells in mouse mammary tumors. Here, we discuss additional findings that clarify this mechanism of Treg-medi...
متن کاملRegulatory T Cells as Immunotherapy
Regulatory T cells (Tregs) suppress exuberant immune system activation and promote immunologic tolerance. Because Tregs modulate both innate and adaptive immunity, the biomedical community has developed an intense interest in using Tregs for immunotherapy. Conditions that require clinical tolerance to improve outcomes - autoimmune disease, solid organ transplantation, and hematopoietic stem cel...
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 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...
