Induction of Indefinite Cardiac Allograft Survival Correlates With Toll-Like Receptor 2 and 4 Downregulation After Serine Protease Inhibitor-1 (Serp-1) Treatment

Abstract

Observed suppressive effects of Serp-1 on early innate immune response components such as TLR-2 and 4, and on adaptive responses such as T-cell intragraft infiltration suggests that Serp-1 may modulate the transition from innate to adaptive immunity, exhibiting a synergistic effect on allograft survival when used in combination with a subtherapeutic dose of CsA.
