Of the 21 analytes that were evaluated, 9 analytes (angiopoietin, CCL3, CCL5, CCL7, CCL12, CXCL10, and TNF-α) were significantly changed in response to infection in both non-pregnant and pregnant mice, and more robust response was, in general, noted in non-pregnant mice (Fig. 4a–g, p < 0.05). Here, CCL3 is linked to infection.
