Specific Response to Infection Flashcards
immune response
the specific response of the body to invasion by pathogens
lymphocytes
small leucocytes with very large nuclei that are vitally important in the specific immune response of the body; they make up the main cellular components of the immune system; they are made in the white bone marrow of the long bones
B cells
lymphocytes that are made and mature in the bone marrow; once they are mature, they are found in the lymph glands and free in the body
immunoglobins
antibodies
B effector cells
lymphocytes that area made and mature in the bone marrow which divide to form the plasma cell clones
plasma cells
cells that produce antibodies to particular antigens at a rate of around 2000 antibodies per second
B memory cells
lymphocytes that are made and mature in the bone marrow and that provide the immunological memory to a specific antigen; they allow the body to respond very rapidly to the same pathogen carrying the same antigen a second time
T cells
lymphocytes made in the bone marrow that mature and become active in the thymus gland
T killer cells
lymphocytes that mature in the thymus gland and produce chemicals that destroy pathogens
T helper cells
lymphocytes that mature in the thymus gland and are involved in the process that produces antibodies against the antigens on a particular pathogen
opsibubs
chemicals which bind to pathogens and label them, so they are more easily recognised by phagocytes
T memory cells
very long-lived cells which constitute part of the immunological memory
major histocompatibility complex (MHC) proteins
proteinss that display antigens on the cell surface membrane
antigen-presenting cell (APC)
a cell displaying an antigen/ MHC protein complex
clone
a group of genetically identical cells which are all produced from one cell
