Regulatory T cells (Tregs) are potent suppressors of immune responses and are
currently being clinically tested for their potential to stop or control
undesired immune responses in autoimmunity, hematopoietic stem cell
transplantation, and solid organ transplantation. Current clinical approaches aim
to boost Tregs in vivo either by using Treg-promoting small molecules/proteins
and/or by adoptive transfer of expanded Tregs. However, the applicability of
Treg-based immunotherapies continues to be hindered by technical limitations
related to cell isolation and expansion of a pure, well-characterized, and
targeted Treg product. Efforts to overcome these limitations and improve
Treg-directed therapies are now under intense investigation in animal models and
pre-clinical studies. Here, we review cell and protein engineering-based
approaches that aim to target different aspects of Treg biology including
modulation of IL-2 signaling or FOXP3 expression, and targeted
antigen-specificity using transgenic T cell receptors or chimeric antigen
receptors. With the world-wide interest in engineered T cell therapy, these
exciting new approaches have the potential to be rapidly implemented and
developed into therapies that can effectively fine-tune immune tolerance.
