Adoptive Immunity Further evidence of adoptive immunity was obtained with the demonstration in 1969 that human liver and kidney recipients acquired new immunoglobulin (Gm) types of donor specificity. From: Transplantation of the Liver (Third Edition), 2015 Related terms: • Virus • T Cell • Cytokine • Humoral Immunity • Vaccine Efficacy • Monospecific Antibody • Immune Response • Mouse F.S. Dhabhar, in Encyclopedia of Stress (Second Edition), 2007 Cell-mediated immunity CMI can be adoptively transferred from an immunized organism to naïve organism by the transfer of T cells and primarily involves cell-mediated clearing mechanisms. Intracellular infectious agents such as certain bacteria (e.g., Listeria monocytogenes or Mycobacterium tuberculosis) and viruses require a CMI response for their elimination. This response involves T helper (Th) cells which recognize infected cells with the help of specialized antigen-presenting cells (APC). On antigen recognition, Th cells release cytokines and chemokines, and they orchestrate a series of reactions involving cytolytic T cells (CTL), macrophages, and NK cells. These cells move to the site of infection and lyse or phagocytose infected cells and destroy them. In addition to their protective effects, CMI responses are also involved in harmful reactions such as organ transplant rejection, graft versus host disease, and certain autoimmune diseases. Delayed type hypersensitivity (DTH) is a form of CMI in which the macrophage is the maj...

Have you ever wondered how your recovery time for the common cold, the flu, or small infections seems to get shorter after you’ve been exposed and successfully recovered the first time? The adaptive immune system, also called acquired immunity, uses specific antigens to strategically mount an immune response. Unlike the innate immune system, which attacks only based on the identification of general threats, the adaptive immunity is activated by exposure to pathogens, and uses an immunological memory to learn about the threat and enhance the immune response accordingly. The adaptive immune response is much slower to respond to threats and infections than the innate immune response, which is primed and ready to fight at all times. Both B cells and T cells are lymphocytes that are derived from specific types of stem cells, called multipotent hematopoietic stem cells, in the bone marrow. After they are made in the bone marrow, they need to mature and become activated. Each type of cell follows different paths to their final, mature forms. After formation and maturation in the bone marrow (hence the name “B cell”), the naive B cells move into the lymphatic system to circulate throughout the body. In the lymphatic system, naive B cells encounter an antigen, which starts the maturation process for the B cell. B cells each have one of millions of distinctive surface antigen-specific receptors that are inherent to the organism’s DNA. For example, naive B cells express antibodies on...

Adoptive immunity acts in a host after their immunological components are withdrawn, their immunological activity is modified extracorporeally, and then reinfused into the same host. There seems to be some variation in usage of this term. • Transferred components are immune cells and autologous as above. • Transfer of immune cells is made between different individuals of • Transfer of cells are made between • Transfer of cells are made between allogeneic hosts. • Transferred components include cells as well as immune molecules such as immunoglobulins between allogeneic hosts. The term is used almost synonymously for " Immunological terms with an adjective " adoptive" [ ] The following terms might indicate procedures involving similar immunological transfer processes.

What is the immune system? The immune system protects your child's body from outside invaders. These include germs such as bacteria, viruses, and fungi, and toxins (chemicals made by microbes). The immune system is made up of different organs, cells, and proteins that work together. There are 2 main parts of the immune system: • The innate immune system. You are born with this. • The adaptive immune system. You develop this when your body is exposed to microbes or chemicals released by microbes. These 2 immune systems work together. The innate immune system This is your child's rapid response system. It is the first to respond when it finds an invader. It is made up of the skin, the eye's cornea, and the mucous membrane that lines the respiratory, gastrointestinal, and genitourinary tracts. These all create physical barriers to help protect your child's body. They protect against harmful germs, parasites (such as worms), or cells (such as cancer). The innate immune system is inherited. It is active from the moment your child is born. When this system recognizes an invader, it goes into action right away. The cells of this immune system surround and cover the invader. The invader is killed inside the immune system cells (called phagocytes). The acquired immune system The acquired immune system, with help from the innate system, makes special proteins (called antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocyte...

The term "adaptive" as used in immunology is problematic as acquired immune responses can be both adaptive and maladaptive in the physiological sense. Indeed, both acquired and innate immune responses can be both adaptive and maladaptive in the evolutionary sense.
