A key concept in fetal immunology is thee induction of tolerance. The fetal imty system must learn to differencish self from non-self with ount mounting harmful responses against maternal tissues.

Biological Mechanisms Underlying thee Association

Several plausible biological mechanisms explain how prenatal exposure to air contenants might increase autoimty disease risk. These mechanisms are nott mutually exclusivy and likely interact in complex ways.

Oxidative Stress andd Inflamation

Air continuaties, sucularly fine particles and ozone, are potent inducers of oksydative stres. Upon inhalation, they generate reactive oxygen species (ROS) in thee lungs and systemaly. In tournant women, this triggers a maternal difficinatory responses specifized bye elevate of cytokines such as IL- 6, TNF- α, and C- reactive protein.

Furthermore, oksydative stress can damage cellular contents, including DNA, proteins, and lipids. In fetal imty cells, this damage may trigger aberrant signaling pathways that promote autoreactivity. The antioksydant capacity of thee fetus is limited, making it especially liable to oksydative insults.

Epigenetics refers to signable changes in genee expression that don not t alter thee DNA sequence itself. DNA methylation, histone modifications, and non-coding RNAs are key epigenetic mechanisms. The environment, including air pollution, can induce epigenetic changes that influence immuno- related genes. During fetal development, epigenetic programming is highly dynamic; errors thi thies process can have lastindices.
