We first choose to measure the mRNA levels for iNOS, a gene that is transcribed in vivo by cardiomyocytes in response to LPS inoculation [40], as well as those for CCL5, CCL7 and CXCL10, three chemokines transcribed in newborn cardiomyocytes after in vitro infection with T. cruzi [27]. This evidence concerns the gene CXCL10 and infection.
