Innate and Adaptive Immune Systems in Physiological and Pathological Pregnancy

Area of Science:

• Immunology
• Reproductive Biology
• Maternal-Fetal Medicine

Background:

• Pregnancy requires dynamic immunological adaptations for successful fetal development.
• Maternal immune tolerance towards the semi-allogeneic fetus is a critical aspect of pregnancy.
• Understanding these immune shifts is vital for both maternal and neonatal health.

Purpose of the Study:

• To provide a comprehensive review of innate and adaptive immunological changes during pregnancy.
• To elucidate the roles of specific immune cells in physiological and pathological pregnancy.
• To identify current challenges and future research directions in pregnancy immunology.

Main Methods:

• Literature review synthesizing current knowledge on pregnancy immunology.
• Analysis of immune cell functions in both normal and complicated pregnancies.
• Identification of knowledge gaps and future research avenues.

Main Results:

• Pregnancy is characterized by orchestrated immunological shifts essential for fetal acceptance.
• Both innate and adaptive immune systems undergo significant, dynamic alterations.
• Specific immune cells play crucial roles in maintaining pregnancy homeostasis and responding to pathology.

Conclusions:

• Immune adaptations are fundamental to successful pregnancy, involving tolerance mechanisms.
• Further research into pregnancy immunology can guide therapeutic interventions for improved maternal and infant outcomes.
• Addressing current challenges will advance the understanding and management of pregnancy-related conditions.
