Adoptive immunity acts in a host after their immunological components are withdrawn, their immunological activity is modified extracorporeally, and then reinfused into the same host. [1] [2] This process in its former part is analogous to adoption: a child is once adopted out from their home, grown up, and then returned to their home of birth. Transferred immunological components include immune cells such as T lymphocytes or tumour-infiltrating lymphocytes, [1] NK cells, macrophages, or B cells. [3]
There seems to be some variation in usage of this term.
The term is used almost synonymously for " passive immunity" in some situations, [7] however, passive immunity acts among xenogeneic hosts; for example, in snake venom immunotherapy, antivenom IgG is obtained from sensitized horse and inoculated to humans. [8]
The following terms might indicate procedures involving similar immunological transfer processes.[ citation needed]
