Pregnancy Pathway, Pregnancy — Maternal Immunological Response
Today: Maternal Immunological Response…or…the Mother/Fetus Dance!
Maternal Immune Response During Pregnancy
Back to work! Thank you for your forebearance while we wrote a chapter for a nursing textbook!
During the course of pregnancy, the mother/fetus dance is ongoing. The maternal immune system and the trophoblast cells continue to influence each other even beyond the implantation.
Because the mother’s immune response modulates near the start of each trimester, the fetus is affected to some degree and mounts a response, as well. For a long time it was thought that maternal and fetal DNA material was not exchanged across the placental membrane, however recent findings indicate that there is some exchange of material. Thus, we all carry some portion of our mother’s DNA and our mother carries some of ours.
What is the impact of this chimeric effect? It depends on how well our DNA gets along!
How does this affect the fetus in utero? The fetus may be affected by clotting issues. Depending on maternal health status s/he may be subject to a stronger or weaker immune system.
How does this affect the mother? Women are more likely than men to develop autoimmune disorders (pregnancy playing a role here), and those who bear male offspring are more likely than those who only have girls to have these disorders.
The maternal/fetal dance goes on.…
Be Prepared for Birth!
