- The programmed death ligands 1 (PD-L1) and 2 (PD-L2) that bind to programmed death 1 (PD-1) have been involved in peripheral tolerance and in the immune escape mechanisms during chronic viral infections and cancer. However, there are no reports about the role of these molecules during Trypanosoma cruzi infection. We have studied the role of PD-L1 and PD-L2 in T. cruzi infection and their importance in arginase/ inducible nitric oxide synthase (iNOS) balance in the immunomodulatory properties of macrophages (M/). In this work, we have demonstrated that expression of the PD-1/PD-L pathway is modified during T. cruzi infection on M/s obtained from peritoneal cavity. The M/s from T. cruziinfected mice suppressed T-cell proliferation and this was restored when anti-PD-1 and anti-PD-L1 antibodies were added. Nevertheless, anti-PDL2 antibody treatment did not re-establish T-cell proliferation. PD-L2 blockade on peritoneal cells from infected mice showed an increase in arginase expression and activity and a decrease in iNOS expression and in nitric oxide (NO) production. Additionally, interleukin-10 production increased whereas interferon-c production was reduced. As a result, this microenvironment enhanced parasite proliferation. In contrast, PD-1 and PD-L1 blockage increased iNOS expression and NO production on peritoneal M/s from T. cruzi-infected mice. Besides, PD-L2 knockout infected mice showed an increased in parasitaemia as well as in arginase activity, and a reduction in NO production. Taken together, our results demonstrate that PD-L2 is involved in the arginase/iNOS balance during T. cruzi infection having a protective role in the immune response against the parasite.
