(A,B) Robust tolerance to A, T-independent (NP, n=4) and B, T-dependent antigen (HEL, n=8) in Siglec-G dependent manner. C, STALs displaying a natural α2-3-sialoside (3’-NeuGc) also induce tolerance to NP in a Siglec-G dependent manner (n=4). In all studies, mice were injected at day 0 with either liposomes displaying antigen alone or liposomes displaying antigen and Siglec-G ligand. On day 14 and 28 all mice received a challenge with liposomes displaying antigen alone. Antibody titers were assessed by ELISA. Data represents mean ± s.e.m.
