From conception, a delicate regulation of galectins, a family of carbohydrate‐binding proteins, is established to ensure maternal immune tolerance in pregnancy. Though galectin‐3 (gal‐3), the only chimera‐type galectin, is abundantly expressed at the feto‐maternal interface; the physiological role of this lectin during pregnancy remains to be fully elucidated and requires further investigation.

嵌合型 galectin-3 是滋养层功能的正调节剂，在妊娠期糖尿病中表达失调。

从受孕开始，就建立了对半乳糖凝集素（一个碳水化合物结合蛋白家族）的微妙调节，以确保母体在怀孕期间的免疫耐受性。尽管 galectin-3 (gal-3) 是唯一的嵌合型半乳糖凝集素，但在胎儿-母体界面大量表达；这种凝集素在怀孕期间的生理作用仍有待充分阐明，需要进一步研究。
