Flashcards in Adaptive/Acquired Immunity Deck (17):
antibody generator-substance that binds to a lymphocyte receptor
has the ability to be bound by a specific antibody (Ab)
substance that induces an immune response when injected into an individual
what makes a good antigen (antigenicity)
host genetics, size, route of administration, adjuvant, complexity, foreignness, dose, chemical stability
what are antigen presenting cells (APC)?
macrophages, lymphocytes (B), dendritic cells
adaptive immune response intracellular antigens
cellular immune response, T lymphocytes, cytotoxic T cells
adaptive immune response extracellular antigens
humoral immune response, B lymphocytes, antibodies
what do T cells provide immunity to?
intracellular bacteria, intracellular virus, fungi, protozoa, tumors
when is the only time that T cells recognize an antigen?
when it is presented on the surface of APC by self MHC molecules
what response processes are mediated by T cells?
infected cells are killed, infected cells are activated and destroy the intracellular organism
