Background
P21 is a secreted protein expressed in all developmental stages of Trypanosoma cruzi. The
Conclusions
Thus, our results shed light on the notion that native P21 is a component related to T. cruzi evasion from the immune response and that CXCR4 may be involved in phagocytosis. P21-His(6) represents an important experimental control tool to study phagocytosis signaling pathways of different intracellular parasites and particles.
