Article Abstract
Background And Aims: Mother-to-child transmission (MTCT) of HIV remains a significant global health challenge, particularly in resource-limited settings. The virus disrupts maternal-fetal immunity through immune dysregulation, placental barrier impairment, and altered antibody transfer, thereby increasing the risk of vertical transmission.
Methods And Results: This narrative review synthesizes current evidence on the immunological and clinical factors influencing MTCT. It highlights how maternal immune exhaustion, placental inflammation, and suboptimal ART timing contribute to transmission. While widespread use of ART has reduced MTCT rates, persistent challenges include late ART initiation, HIV drug resistance, co-infections, and transmission through breastfeeding. Emerging strategies-such as maternal immune modulation, monoclonal antibody therapies, and tailored ART regimens-show potential for further risk reduction.
Conclusion: To effectively minimize MTCT, comprehensive prevention approaches are essential. These should combine medical interventions with maternal nutrition support, co-infection management, and safe breastfeeding practices under ART coverage. A multifaceted strategy is key to protecting both maternal and infant health.

Innate-like T cells (ILT), including γδ T cells (Vδ2s), Natural Killer T cells (NKTs) and Mucosal-associated Invariant T cells (MAITs), integrate innate and adaptive immunity, playing important roles in homeostatic conditions as well as during infection or inflammation. ILT are present on both sides of the fetal-maternal interface, but our knowledge of their phenotypical and functional features in neonates is limited. Using spectral flow cytometry we characterized cord blood ILT in neonates born to healthy women and women living with HIV.

Maternal-fetal microchimerism is increasingly linked with both inflammatory disorders and immune tolerance phenotypes. However, finding microchimeric cells in target tissues does not establish causality, which require platforms for manipulating these rare and heterogeneous cells. Here, we studied maternal microchimeric cells (MMc) that sustain non-inherited maternal antigen (NIMA) tolerance.

Emerging evidence suggests a potential link between maternal SARS-CoV-2 infection during early pregnancy and the development of congenital heart defects (CHD) in offspring. Although vertical transmission of SARS-CoV-2 is rare, the virus has been associated with placental complications and increased maternal morbidity. Recent studies from China report increased rates of CHD and anomalies such as situs inversus when infection occurs during gestational weeks 4-6, a critical window for cardiac development.

Extracellular Vesicles (EVs) are small, membrane-bound particles released by cells into biological fluids, where they function as mediators of intercellular communication. These vesicles transport a diverse array of bioactive molecules, including proteins, lipids, and nucleic acids, and play essential roles in regulating physiological and pathological processes. Recent research has revealed the significance of EVs in reproductive biology, particularly in the areas of spermatozoa maturation, oocyte development, embryo implantation, and maternal-fetal interactions.

Autoimmune diseases present a clinical challenge for young women of childbearing age since pregnancy can affect their progression and lead to complications for both mother and baby. Systemic lupus erythematosus (SLE) is of particular interest in this context due to its association with an increased risk of spontaneous abortion, foetal death, pre-eclampsia, intrauterine growth restriction, preterm delivery, and various neonatal manifestations, including thrombocytopenia. In this context, autoimmune neonatal thrombocytopenia, caused by the transplacental transfer of maternal autoantibodies, may be the first sign of an undiagnosed autoimmune disease in the mother.
