Regulatory t-cells
WebProgrammed death-1 (PD-1) also has a pivotal role in regulation of T-cell functions during chronic viral infection. To examine the role of PD-1 pathway in regulating T (R)-cell functions that inhibit T-cell responses during virus-associated malignancy, T (R) cells were investigated in the setting of hepatitis C virus-associated lymphoma (HCV-L ... T regulatory cells are a component of the immune system that suppress immune responses of other cells. This is an important "self-check" built into the immune system to prevent excessive reactions. Regulatory T cells come in many forms with the most well-understood being those that express CD4, CD25, … See more The regulatory T cells , formerly known as suppressor T cells, are a subpopulation of T cells that modulate the immune system, maintain tolerance to self-antigens, and prevent autoimmune disease. Treg cells are See more The immune system must be able to discriminate between self and non-self. When self/non-self discrimination fails, the immune system destroys cells and tissues of the body and as a result causes autoimmune diseases. Regulatory T cells actively suppress … See more An important question in the field of immunology is how the immunosuppressive activity of regulatory T cells is modulated during the course of an ongoing immune … See more Genetic mutations in the gene encoding FOXP3 have been identified in both humans and mice based on the heritable disease caused by these mutations.
