immune thrombocytopenic purpura	An autoimmune disorder in which the immune system destroys platelets. The destruction of platelets leads to abnormal blood clotting and easy or excessive bruising and bleeding. The exact cause of idiopathic thrombocytopenia purpura is unknown; however, the disorder may develop with a viral infection, including HIV.
immunity	Protection against disease caused by infectious microorganisms or by other foreign substances. There are two main types of immunity: innate and acquired.
immunization	Giving a vaccine to stimulate a person's immune response. Vaccination can be intended either to prevent a disease (a preventive vaccine) or to treat a disease (a therapeutic vaccine)
immunocompetent	When the body is able to produce a normal immune response.
immunocompromised	When the body is unable to produce an adequate immune response. A person may be immunocompromised because of a disease or an infection, such as HIV, or as the result of treatment with drugs or radiation.
immunodeficiency	Inability to produce an adequate immune response because of an insufficiency or absence of antibodies, immune cells, or both. Immunodeficiency disorders can be inherited, such as severe combined immunodeficiency; they can be acquired through infection, such as with HIV; or they can result from chemotherapy.
immunogenicity	The ability or the extent to which a substance is able to stimulate an immune response.
immunoglobulin	A protein produced by B lymphocytes (B cells) in response to an antigen. Antibodies bind to and help destroy antigens.
immunologic	Pertaining to the immune system.
immunologic failure	A type of HIV treatment failure. There is no consensus on the definition of immunologic failure. However, some experts define immunologic failure as the failure to achieve and maintain adequate CD4 counts despite viral suppression.
immunomodulator	A natural or synthetic substance that modifies (activates, enhances, or suppresses) the immune response or the functioning of the immune system.
immunomodulatory therapy	Use of immunologic agents such as antibodies, growth factors, and vaccines to modify (activate, enhance, or suppress) the immune system in order to treat disease. Immunotherapy is also used to diminish adverse effects caused by some cancer treatments or to prevent rejection of a transplanted organ or tissue.
immunosuppression	When the body's ability to mount an immune response to fight infections or disease is reduced. Immunosuppression may result from certain diseases, such as HIV/AIDS, or as a result of radiotherapy or chemotherapy. Immunosuppression may also be deliberately induced by drugs used to prevent rejection of transplanted organs.
immunotherapy	Use of immunologic agents such as antibodies, growth factors, and vaccines to modify (activate, enhance, or suppress) the immune system in order to treat disease. Immunotherapy is also used to diminish adverse effects caused by some cancer treatments or to prevent rejection of a transplanted organ or tissue.

in utero	In the uterus (womb) In utero also refers to the length of time that a fetus is in the uterus of the pregnant female.
in vitro	In an artificial environment outside the body, such as in a test tube in a laboratory.
