Adhesion of Trypanosoma cruzi to host cells employs mechanisms which are complex and not completely understood. Upon infection, host cells release pro-inflammatory cytokines and chemokines in the environment. These had been found to be involved with increasing parasite uptake as well as killing by macrophages and cardiomyocytes. In the present study, we focused on the interaction of murine beta-chemokine CCL2 with trypomastigote forms of T. cruzi. We found that this chemokine directly triggers the chemotaxis and morphogenesis of trypomastigote forms of parasites. Binding assays showed that the interaction of CCL2 with molecules present in trypomastigote forms is abolished by the addition of condroitin 6-sulphate, a glycosaminoglycan. Moreover, we also observed that the parasite glycoproteins are the major players in this interaction. In summary, our study demonstrates a host ligand/parasite receptor interaction that may have relevant implications in the tissue tropism of this important parasitic disease.
