免疫耐受指的是免疫活性细胞在接触抗原性物质时人的自身的免疫系统表现出的一种无应答状态。母体免疫耐受机制这些年一直是许多学者都在细心研究的热点问题。胚胎是作为半异己的移植物存在于母体,对母体来说具有抗原性。根据免疫学抗原抗体反应的原理推断,母体对胚胎这一外来物能够产生免疫反应,该免疫反应很有可能会导致流产,但是最终胚胎都完好的存在于母体,说明胚胎在母体内存在免疫耐受现象。胚胎能够完好的存在于母体说明母体免疫系统受到一定的抑制,但是又能够对胚胎产生适度的免疫抵抗,这两者之间存在一种微妙的平衡关系。研究发现母体对胚胎的这一免疫耐受现象与许多因素有关。
Immune tolerance refers to a non-responsive condition in which the immune-competent cells exhibit their own immune system when exposed to antigenic substances. Maternal immune tolerance mechanism These years has been a hot issue that many scholars are carefully studying. The embryo is present as a hemizygotic graft in the mother and is antigenic to the mother. According to the principle of immunological antigen antibody reaction, the maternal body can exert an immune response to the foreign body of the embryo. This immune reaction is likely to cause miscarriage, but the final embryo is intact in the mother, indicating that the embryo has immune tolerance in the mother By the phenomenon. Embryos can exist intact in the mother that the mother’s immune system is a certain degree of inhibition, but also able to moderate embryonic immune resistance, there is a delicate balance between the two. The study found that maternal immune tolerance to the embryo with many factors.
