Many specific diseases directly or indirectly cause immunosuppression.
Dysfunction of the immune system can cause autoimmune diseases, inflammatory diseases and cancer. Immunodeficiency occurs when the immune system is less active than normal, resulting in recurring and life-threatening infections.

The disease is characterized by hypogammaglobulinemia, frequent infections and the occurrence of autoimmune diseases. In individuals, the disease may manifest itself differently, with in some cases only a partial reduction in the number of Tregs , in others the ability to bind CTLA-4 ligand has been reduced, resulting in disruption homeostasis ...
