a Two simplified complementary shapes characterized by the points (xP,yP) and (xP,−yP), respectively, in the peptide lattice. b Simplified graphical representation of the difference between the ERS and the CRS models. Dark blue: area allocated to regulatory T cells; Green: area for potential infection specific T cells; Intensity of the colors represent the density of T cells in the area (a darker color means larger density)
