Galectins (Gal) are characterized by their affinity for galactoside structures on glycoconjugates. This relationship is mediated by carbohydrate recognition domains, which are multifunctional regulators of basic cellular biological processes with high structural similarity among family members. They participate in both innate and adaptive immune responses, as well as in reproductive immunology. Recently, the discovery that galectins are highly expressed at the maternal-fetal interface has garnerd the interest of experts in human reproduction. Galectins are involved in a variety of functions such as maternal-fetal immune tolerance, angiogenesis, trophoblast invasion and placental development and are considered to be important mediators of successful embryo implantation and during pregnancy. Dysregulation of these galectins is associated with abnormal and pathological pregnancies (e.g., preeclampsia, gestational diabetes mellitus, fetal growth restriction, preterm birth). Our work reviews the regulatory mechanisms of galectins in normal and pathological pregnancies and has implications for clinicians in the prevention, diagnosis and treatment of pregnancy-related diseases.

UI MeSH Term Description Entries
D007231 Infant, Newborn An infant during the first 28 days after birth. Neonate,Newborns,Infants, Newborn,Neonates,Newborn,Newborn Infant,Newborn Infants
D010920 Placenta A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES). Placentoma, Normal,Placentome,Placentas,Placentomes
D010929 Placentation The development of the PLACENTA, a highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products between mother and FETUS. The process begins at FERTILIZATION, through the development of CYTOTROPHOBLASTS and SYNCYTIOTROPHOBLASTS, the formation of CHORIONIC VILLI, to the progressive increase in BLOOD VESSELS to support the growing fetus. Hemochorial Placental Development,Hemochorial Placentation,Placental Development,Placental Development, Hemochorial,Placentation, Hemochorial
D011247 Pregnancy The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH. Gestation,Pregnancies
D005260 Female Females
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D014327 Trophoblasts Cells lining the outside of the BLASTOCYST. After binding to the ENDOMETRIUM, trophoblasts develop into two distinct layers, an inner layer of mononuclear cytotrophoblasts and an outer layer of continuous multinuclear cytoplasm, the syncytiotrophoblasts, which form the early fetal-maternal interface (PLACENTA). Cytotrophoblasts,Syncytiotrophoblasts,Trophoblast,Cytotrophoblast,Syncytiotrophoblast
D047928 Premature Birth CHILDBIRTH before 37 weeks of PREGNANCY (259 days from the first day of the mother's last menstrual period, or 245 days after FERTILIZATION). Preterm Birth,Birth, Premature,Birth, Preterm,Births, Premature,Births, Preterm,Premature Births,Preterm Births
D037161 Galectins A class of animal lectins that bind specifically to beta-galactoside in a calcium-independent manner. Members of this class are distiguished from other lectins by the presence of a conserved carbohydrate recognition domain. The majority of proteins in this class bind to sugar molecules in a sulfhydryl-dependent manner and are often referred to as S-type lectins, however this property is not required for membership in this class. Galaptins,Lectins, S-Type,D-Galactoside-Binding Lectin,Galactose-Binding Lectin,Galectin,S-Type Lectin,S-Type Lectins,beta-D-Gal(1-3)D-GalNAc Specific Lectins,beta-D-Galactosyl-Specific Lectin,beta-Galactoside Binding Lectin,Binding Lectin, beta-Galactoside,D Galactoside Binding Lectin,Galactose Binding Lectin,Lectin, D-Galactoside-Binding,Lectin, Galactose-Binding,Lectin, S-Type,Lectin, beta-D-Galactosyl-Specific,Lectin, beta-Galactoside Binding,Lectins, S Type,S Type Lectin,S Type Lectins,beta D Galactosyl Specific Lectin,beta Galactoside Binding Lectin
