Article Abstract

As the first T cell immunoglobulin mucin (Tim) family member to be identified, Tim-3 is a powerful immune checkpoint that functions in immunoregulation and induction of tolerance. Conventionally, Tim-3 is considered to play a role in adaptive immunity, especially in helper T cell-mediated immune responses. As researches progress, Tim-3 has been detected in a wider range of cell types, modulating cell function through ligand-receptor interactions and other pathways. Strikingly, Tim-3 plays a pivotal role in maternal-fetal tolerance by regulating immune cell functions and orchestrating the maternal-fetal cross-talk. In this review, we elaborate on the involvement of Tim-3 in immunology, with a focus on its participation in maternal-fetal tolerance to provide new insights into immunoregulation during pregnancy. Our work will be helpful in further understanding the pathogenesis of pregnancy-related diseases and will inspire new strategies for their diagnosis and treatment.

Tolerance to non-inherited maternal antigen is sustained by LysM CD11c maternal microchimeric cells.

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.

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.

The placenta is a complex organ with multiple immune and non-immune cell types that promote fetal tolerance and facilitate the transfer of nutrients and oxygen. The nonhuman primate (NHP) is a key experimental model for studying human pregnancy complications, in part due to similarities in placental structure, which makes it essential to understand how single-cell populations compare across the human and NHP maternal-fetal interface. We constructed a single-cell RNA-Seq (scRNA-Seq) atlas of the placenta from the pigtail macaque ( ) in the third trimester, comprising three different tissues at the maternal-fetal interface: the chorionic villi (placental disc), chorioamniotic membranes, and the maternal decidua.

Decidualization is the transformation of endometrial stromal cells into functionally specialized cells during the early stages of pregnancy. Occurring in mammals that develop invasive hemochorial placentae, decidualization is a pivotal evolutionary adaptation in mammals that supports pregnancy establishment, implantation, and placentation in a limited number of animal species. During decidualization, an endometrial stromal cell undergoes profound genetic, epigenetic, and proteomic changes, allowing it to prevent immunological rejection and fostering the development of a newly implanted embryo.

This study investigated the expression of immune checkpoint molecules on CD4 and CD4 NKT cell subpopulations throughout healthy pregnancy trimesters and in non-pregnant condition to understand their role in maternal-fetal immunotolerance. Using flow cytometry, we found that CD4 NKT cells significantly outnumbered CD4 NKT cells in all investigated groups. In the case of the immune checkpoint molecules, PD-1 receptor expression was significantly lower in CD4 NKT cells compared to CD4 counterpart cells only in non-pregnant women, while the PD-L1 ligand expression on CD4 NKT cells significantly decreased in the third trimester.
