The inability of the body to develop antibodies to invading bacteria may result from infection with HIV, which invades white blood cells—primarily monocytes, macrophages, and helper T lymphocytes. Multiomic immune clockworks of pregnancy, given the pivotal role for the transcription factor CREB in immune cell survival, it is possible that the increased basal CREB signaling tone observed early in pregnancy confers a survival advantage on peripheral NK cells, allowing them to contribute, as mature or precursor cells, to the pool of decidual NK cells. Blood is taken to determine if antibodies are being produced. Abnormal numbers of certain cells can indicate an immune system defect.

If a high number of sperm antibodies come into contact with a man’s sperm, it may be hard for the sperm to fertilize an egg.

However, even if alternatives exist to avoid the use of radioactivity (22), such tests remain cumbersome and difficult to implement. These antibodies help protect the body against infection by attaching to specific invading microorganisms, toxins, or other foreign substances (antigens), marking them for destruction. Disorders of the immune system can result in autoimmune diseases, inflammatory diseases and cancer, according to the NIH. Stem cell transplantation uses stem cells from a donor, usually a parent or relative, to build a normally functioning immune system.
