CXCR3 and infection: As we can see in the Fig 2B, mice treated with isotype control antibody displayed low levels of parasitemia and did not change the already described parasitemia profile after infection with the Y strain of T. cruzi. Interestingly, on day 9 after infection (the peak), the anti-CXCR3 treated group had higher parasitemia compared to the Isotype control group (Fig 2B).
