In Silico Screening: Tregitopes

Tregitope

Tregitopes are a set of peptides that specifically activate CD4+CD25+FoxP3+ natural regulatory T cells (nTregs). Tregitopes are promiscuous MHC Class II T cell epitopes located in the Fc and framework regions of Fab from IgG. In vitro, co-incubation of antigens with Tregitopes in vitro leads to a suppression of effector cytokine and chemokine secretion, reduced proliferation of effector T cells, and expansion of antigen-specific adaptive Tregs (aTregs). In vivo, co-administration of Tregitopes with a wide range of proteins (such as FVIII, thyroid stimulating hormone receptor, ovalbumin, and autoantigens) leads to suppression of T cell and antibody responses to test antigens.
