Biomarkers and immunoprofiles associated with fetal abnormalities of ZIKV-positive pregnancies.


ABSTRACT:

Background

An intricate fetal-maternal immune crosstalk during pregnancy is essential for a healthy birth. Hence, the infection-induced alterations of maternal immunity often lead to adverse outcomes for mother and/or child. The emergence of Zika virus (ZIKV) infection in pregnant women has been associated with more than 3,000 cases of microcephaly and nervous system malformations.

Methods

To explore the potential correlation of ZIKV-induced alteration of maternal immunity with fetal abnormalities, we performed extensive sera immunoprofiling of 74 pregnant women: 30 symptomatic ZIKV+ pregnant patients and 30 healthy pregnant controls in ZIKV-endemic Rio de Janeiro, along with 14 healthy pregnant controls in non-endemic Los Angeles.

Results

Extensive multiplexing analysis of 69 cytokines revealed that CXCL10, CCL2, and CCL8 chemokines were specifically associated with symptomatic ZIKV+ infection during pregnancy, and distinct immunoprofiles were detected at different trimesters in ZIKV-infected pregnant women. Intriguingly, the high CCL2 level and its inverse correlation with CD163, TNFRSF1A, and CCL22 levels was apparently associated with ZIKV-induced abnormal birth.

Conclusion

Our findings provide insights into the alteration of ZIKV-elicited maternal immunity, serving as a potential clinical biomarker platform.
