| Regulatory T cells (Tregs) have the role of regulating self-tolerance, and suppressing immune responses. Defects
in Treg function and number can lead to in loss of tolerance or autoimmune disease. To treat or control autoimmune diseases, one of the options is to develop immune tolerance for Tregs cell therapy, which includes
promotion and activation. Recently, cell-based treatment as a promising approach to increase cells function and
number has been developed. Cell therapy by chimeric T antigen receptor (CAR-T) cells has shown signifcant
effcacy in the treatment of leukemia, which has led researchers to use CAR-T cells in other diseases like autoimmune diseases. Here, we describe the existing treatments for autoimmune diseases and the available treatments based on Treg, their benefts and restrictions for implementation in clinical trials. We also discussed
potential solutions to overcome these limitations. It seems novel designs of CARs to be new hope for autoimmune
diseases and expected to be a potential cure option in a wide array of disease in the future. Therefore, it is very
important to address this issue and increase information about it. |
