Infections can develop in the neonate The way in which the virus interacts with the maternal immune system, the maternal-fetal interface and the placenta explain these results and also the differences that are Although the exact pathophysiology of CMV is unknown, the severity of the infection and fetal consequences are dependent on Even in the absence of maternal-to-fetal transmission, previous epidemics of many emerging viral threats have resulted in poor Neonates can have sequelae from maternal infections even with full-term development 11, demonstrating that the fetal response to infection is not restricted to effects of Abstract During pregnancy, the maternal immune system must navigate a balance between fetal tolerance and a response to acquired microbial infections. Although many maternal and fetal cell types activate innate immune signalling pathways in response to infections, excessive inflammation can disrupt tolerance, affect placental function This critical window of immune development bridges prenatal immune tolerance with the need for postnatal environmental protection, Researchers discovered that a fetus has a functional immune system that is well-equipped to combat infections in its developing The development of the fetal immune response is a highly complex process. The transfer may Throughout gestation, the maternal-fetal interface must balance the divergent demands of immunotolerance towards the semi-allogenic fetus and immune defense against In contrast to the previous belief that the fetal immune response is inert, it is now thought that the fetal immune response is uniquely tolerant to maternal and allo-antigens, but The maternal-fetal interface is a unique immunological environment that balances fetal tolerance with immune protection and protects both the mother and fetus from infections Maternal immune states arising from pregnancy-associated infections and immunizations can impact these pathways and have long-term consequences on offspring This review article is designed to address the bacterial and viral infections that threaten pregnancy and their possible outcomes. The major infections which can be transmitted from the mother to the fetus and can probably result in Bovine Viral Diarrhea Virus (BVDV) fetal infections occur in two forms; persistent infection (PI) or transient infection (TI), depending on what In this article, we review the complexity of the interaction between various host factors associated with different maternal infections and dynamic Moreover, specific immune adaptations like suppression of humoral and cell-mediated immune systems during pregnancy protect against fetal rejection and at the same This study provides insight into the maternal-fetal immune responses triggered by SARS-CoV-2 and emphasizes the rarity of placental infection. Alterations in systemic maternal immunity and cellular dialogue at the maternal-fetal interface combine to maintain tolerance of Infections in pregnancy may lead to fetal morbidity and mortality. In the present review, we describe the development of the fetal immune response and the role of the We will also discuss how changes in the intrauterine environment as a consequence of maternal immune cell activation contribute to placental diseases and Thus, during the second trimester, immune cells, predominantly lymphocytes, grow in number, mature, and differentiate. Viral infections in pregnancy are major causes of maternal and fetal morbidity and mortality. Moreover, training of the fetal immune Research revealed that foetuses are not as defenceless as once thought; they can actually fight infections from within the womb. Bovine Viral Diarrhea Virus (BVDV) fetal infections occur in two forms; persistent infection (PI) or transient infection (TI), depending on what stage of gestation the fetus is A range of innate immune mechanisms can respond to pathogens in both the decidua and the placenta (3, 4). Here, we review the innate immune pathways involved in the response to teratogenic pathogens at the maternal–fetal interface and their impacts on fetal health and The widely studied maternal immune system to fetal and neonatal immunity is the transfer of immunoglobulin's from mother to fetus. The maternal-fetal Abstract The innate immune system’s recognition of microorganisms through pattern recognition receptors (PRRs) is a fundamental aspect of host defense and microbial .
