Autoimmune Lymphoproliferative Syndrome (ALPS) is an inherited disorder of the immune system that affects both children and adults. In ALPS and related disorders with defective cell kill and proliferation pathways, unusually high numbers of white blood cells, called lymphocytes, accumulate in the lymph nodes, liver, and spleen, which can lead to enlargement of these organs. ALPS can also cause a variety of autoimmune problems such as anemia (low red blood cell count), thrombocytopenia (low platelets), and neutropenia (low neutrophil count). Lymphocytes infiltrating the bone marrow, lungs, liver, and brain can also lead to clinical symptoms. The ALPS Unit aims to better understand these rare diseases of lymphocyte apoptosis and immune homoeostasis, to find their genetic causes, and to uncover new ways to treat them. Its ultimate goal is to find a cure for these disorders of the immune system.
