Immune Tolerance Dysfunction in Pregnancy Due to Ambient Air Pollution

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this project is to study the effects of air pollution toxicants on pregnant mothers' immune health during and after pregnancy. Using already collected samples, this study proposes to evaluate changes in immune function in response to air pollution with the use of innovative technologies, to identify the drivers of immune dysfunction and potential modifiable factors, and to determine how these immune findings are associated with pollution exposure and outcomes of disease.
