Natural killer
Natural killer (NK) cells are regulated by the immune system. In women who have autoimmune issues, the NK cells can react abnormally to an implanting embryo, treating it as an invading cell and signaling for the body to attack it.
Intralipids have been shown to lower the activity of the NK cells component of our immune system.
New research has suggested that women who have experienced recurrent miscarriages or multiple failed IUI or IVF cycles as a result of NK cell activation may benefit from the use of intralipids.
What are Natural Killer Cells?
Natural killer (NK) cells are a subvariety of the white blood cells it’s the basis for the body’s defense mechanism. They fight and safeguard the body against harmful tumors, infections, and bacteria etc. It’s important to observe the role of NK cells when the body is normal and when it’s affected by the disease. It’s amazing to know that each organ in our body has NK cells to protect the organ, and the womb has the most NK cells. Here, NK cells play their role to support the blood supply for the development of the fetus, and to detect if any foreign cells are entering into the body from the father’s cells or egg donations if they are body-friendly. However, if the count of NK cells is more than normal, they are destructive. They impact negatively and begin to attack rather than safeguarding the pregnancy, and leads to abortion or miscarriage. In few cases, extremely high levels of NK cells do not allow the implantation to happen.
