Research Abstract

The incidence of colon cancer in mice deficient for IL-10 was not increased by PD-1 deficiency. We have found that PD-1 and AIDA (LAG-3) additively suppressed the activation of T cells upon antigen stimulation. We have analyzed mice deficient for both PD-1 and AIDA (LAG-3) and found that regulatory T cells retained the regulatory function and T cells were biased toward Thl in these mice.
